Unlock Brand Recognition in Emails: Free #BIMI #API from AvatarAPI.com

https://www.avatarapi.com/

Email marketing is more competitive than ever, and standing out in crowded inboxes is a constant challenge. What if there was a way to instantly make your emails more recognizable and trustworthy? Enter BIMI – a game-changing email authentication standard that’s revolutionizing how brands appear in email clients.

What is BIMI? (In Simple Terms)

BIMI stands for “Brand Indicators for Message Identification.” Think of it as a verified profile picture for your company’s emails. Just like how you recognize friends by their profile photos on social media, BIMI lets email providers display your company’s official logo next to emails you send.

Here’s how it works in everyday terms:

  • Traditional email: When Spotify sends you an email, you might only see their name in your inbox
  • BIMI-enabled email: You’d see Spotify’s recognizable logo right next to their name, making it instantly clear the email is legitimate

This visual verification helps recipients quickly identify authentic emails from brands they trust, while making it harder for scammers to impersonate legitimate companies.

Why BIMI Matters for Your Business

Instant Brand Recognition: Your logo appears directly in the inbox, increasing brand visibility and email open rates.

Enhanced Trust: Recipients can immediately verify that emails are genuinely from your company, reducing the likelihood they’ll mark legitimate emails as spam.

Competitive Advantage: Many companies haven’t implemented BIMI yet, so adopting it early helps you stand out.

Better Deliverability: Email providers like Gmail and Yahoo prioritize authenticated emails, potentially improving your delivery rates.

German Vehicle #KBA #API: Complete Guide to German Car Data Lookup Using KBA Numbers

https://www.kbaapi.de/
Audi R8 Spyder 5.2 FSI quattro in Kupferzell

Germany represents Europe’s largest automotive market and home to world-renowned manufacturers like BMW, Mercedes-Benz, Audi, and Volkswagen. Unlike most vehicle registration APIs that use license plates, the German Vehicle API operates using KBA numbers (Kraftfahrt-Bundesamt codes) – unique identifiers registered with the Federal Motor Transport Authority. (https://www.kbaapi.de/)

Understanding the German KBA System

The Kraftfahrt-Bundesamt (KBA) is Germany’s Federal Motor Transport Authority, responsible for vehicle type approvals and maintaining the central database of vehicle specifications. Every vehicle model sold in Germany receives a unique KBA number that identifies its exact specifications, engine type, and technical details.

What is a KBA Number?

A KBA number consists of two parts in the format HSN/TSN:

  • HSN (Herstellerschlüsselnummer) – Manufacturer key number
  • TSN (Typschlüsselnummer) – Type key number

Together, these numbers uniquely identify a specific vehicle model variant, including engine specifications, body type, and equipment levels.

Where to Find KBA Numbers

KBA numbers can be found in several locations on German vehicle documentation:

  • Vehicle Registration Certificate (Part 1) – Fields 2.1 and 2.2
  • Vehicle Registration Document – Boxes 2 and 3
  • Certificate of Conformity – Technical documentation
  • Insurance Documents – Often included in policy details

German Vehicle API Features

The German endpoint provides comprehensive technical specifications for vehicles registered in Germany:

Available Data

When querying German vehicle records using KBA numbers, you can retrieve:

  • Make and Model – Complete manufacturer and model designation
  • Engine Specifications – Power in both KW and horsepower (PS)
  • Engine Capacity – Displacement in cubic centimeters
  • Fuel Type – Petrol (Benzin), diesel, electric, or hybrid classifications
  • Technical Period – Years of manufacture for this specification
  • Representative Images – Visual identification of the vehicle type

Sample Response Format

{
  "Description": "ALFA GIULIETTA Spider 1.3 [196101 - 196212] (59kW 80hp Otto AR 00508)",
  "CarMake": {
    "CurrentTextValue": "alfa romeo"
  },
  "CarModel": {
    "CurrentTextValue": "GIULIETTA SPIDER"
  },
  "MakeDescription": {
    "CurrentTextValue": "alfa romeo"
  },
  "ModelDescription": {
    "CurrentTextValue": "GIULIETTA SPIDER"
  },
  "PowerKW": 59,
  "PowerHP": 80,
  "EngineSize": 1281,
  "Fuel": "Benzin"
}

API Implementation

Endpoint Usage

The German Vehicle API uses the /CheckGermany endpoint and requires two parameters:

  1. KBA Number – In HSN/TSN format (e.g., “4000/305”)
  2. Username – Your API authentication username

Basic Implementation Example

// JavaScript example for German KBA lookup
async function lookupGermanVehicle(kbaNumber, username) {
  const apiUrl = `https://www.regcheck.org.uk/api/reg.asmx/CheckGermany?KBANumber=${kbaNumber}&username=${username}`;
  
  try {
    const response = await fetch(apiUrl);
    const xmlText = await response.text();
    
    // Parse XML response
    const parser = new DOMParser();
    const xmlDoc = parser.parseFromString(xmlText, "text/xml");
    const jsonData = xmlDoc.getElementsByTagName("vehicleJson")[0].textContent;
    const vehicleInfo = JSON.parse(jsonData);
    
    return {
      make: vehicleInfo.MakeDescription.CurrentTextValue,
      model: vehicleInfo.ModelDescription.CurrentTextValue,
      powerKW: vehicleInfo.PowerKW,
      powerHP: vehicleInfo.PowerHP,
      engineSize: vehicleInfo.EngineSize,
      fuel: vehicleInfo.Fuel,
      description: vehicleInfo.Description
    };
  } catch (error) {
    console.error('German KBA lookup failed:', error);
    return null;
  }
}

// Usage example
lookupGermanVehicle("4000/305", "your_username")
  .then(data => {
    if (data) {
      console.log(`Vehicle: ${data.make} ${data.model}`);
      console.log(`Power: ${data.powerKW}kW (${data.powerHP}hp)`);

Comparison with License Plate Systems

Why KBA Numbers Instead of License Plates?

The German system’s use of KBA numbers instead of license plates reflects several key differences:

Technical Precision:

  • KBA numbers identify exact technical specifications
  • License plates only identify individual vehicles
  • Multiple vehicles can share the same KBA specifications

Privacy Protection:

  • KBA lookups don’t reveal personal ownership information
  • License plate systems often include owner data
  • Complies with strict German data protection laws (GDPR)

Standardization:

  • KBA numbers are consistent across all German states
  • License plate formats vary by region and time period
  • Technical specifications remain constant regardless of registration location

Alternative: German License Plate Availability

For developers specifically needing German license plate availability checking, a separate service is available through RapidAPI. However, this service only checks if a license plate combination is available for registration, not vehicle specifications.

Data Coverage and Limitations

Coverage Scope

  • Complete KBA Database – All vehicles approved for German market
  • Historical Data – Vehicles from 1960s onwards
  • Technical Accuracy – Official specifications from Federal Motor Transport Authority
  • Regular Updates – Database maintained with current approvals

Limitations

  • KBA Number Required – Cannot lookup by license plate
  • German Market Only – Covers vehicles approved for German sale
  • Technical Focus – Provides specifications, not ownership data
  • Import Vehicles – Limited data for non-German market vehicles

Getting Started with German KBA API

# Usage example
result = lookup_usa_vehicle("ABC1234", "CA", "your_username")
print(result)

Rate Limiting and Credits

The USA Vehicle API operates on a credit-based system:

  • Each successful lookup consumes one credit
  • Failed lookups (no data found) typically don’t consume credits
  • Monitor your credit balance to avoid service interruptions
  • Consider implementing local caching for frequently accessed data

Data Validation

Before making API calls, validate input parameters:

function validateUSALookup(plateNumber, state) {
  // Valid US state codes
  const validStates = [
    'AL', 'AK', 'AZ', 'AR', 'CA', 'CO', 'CT', 'DE', 'FL', 'GA',
    'HI', 'ID', 'IL', 'IN', 'IA', 'KS', 'KY', 'LA', 'ME', 'MD',
    'MA', 'MI', 'MN', 'MS', 'MO', 'MT', 'NE', 'NV', 'NH', 'NJ',
    'NM', 'NY', 'NC', 'ND', 'OH', 'OK', 'OR', 'PA', 'RI', 'SC',
    'SD', 'TN', 'TX', 'UT', 'VT', 'VA', 'WA', 'WV', 'WI', 'WY',
    'DC', 'GU', 'PR', 'VI'
  ];
  
  if (!plateNumber || plateNumber.length < 2 || plateNumber.length > 8) {
    return { valid: false, error: "Invalid plate number length" };
  }
  
  if (!validStates.includes(state.toUpperCase())) {
    return { valid: false, error: "Invalid state code" };
  }
  
  return { valid: true };
}

Limitations and Coverage

Data Availability

  • Coverage varies by state based on data sharing agreements
  • Some states may have limited historical data
  • Newer registrations typically have more complete information
  • Commercial vehicles may have different data availability

Privacy Considerations

  • The API provides vehicle specifications, not personal owner information
  • All data returned is from publicly available vehicle registration records
  • Comply with local privacy laws when storing or processing vehicle data
  • Consider data retention policies for cached information

Filling the Gaps: Introducing NicheVinDecoder – A Specialized #VIN Library for Forgotten Vehicles

When was the last time you tried to decode a VIN for an RV, specialty trailer, or electric scooter only to get a frustrating “manufacturer not found” error? If you’ve worked with vehicle data beyond mainstream cars and trucks, you’ve probably hit this wall more times than you’d care to count.

The standard NHTSA VIN decoder works brilliantly for Ford, Toyota, and GM vehicles. But what happens when you’re dealing with a Highland Ridge travel trailer, a Segway electric scooter, or a custom-built utility trailer? You’re often left with nothing but the basic World Manufacturer Identifier and a lot of guesswork.

That’s exactly the problem that led us to create NicheVinDecoder – an open-source .NET library specifically designed to decode VINs from the manufacturers that traditional decoders leave behind.

The Problem: A Tale of Two VIN Decoders

Picture this scenario: You’re building an application for an RV dealership. A customer walks in with a 2023 Highland Ridge Open Range travel trailer, VIN number 58TBM0BU8P3A13051. You run it through a standard VIN decoder and get:

Manufacturer: Highland Ridge RV (maybe)
Model Year: 2023
Everything else: Unknown

But with NicheVinDecoder, that same VIN reveals:

Manufacturer: Highland Ridge RV
Model Year: 2023
Model: Open Range 330BHS Travel Trailer
Body Style: RV Trailer [Standard] Enclosed Living Quarters
Trailer Type: Ball Pull (Travel Trailer)
Axle Configuration: Two Axles (Tandem)
Length: 38 ft - less than 40 ft
Plant Location: 3195 N. SR 5, Shipshewana, IN 46565
Model Code: A1 (330BHS)
Sequential Production Number: 3051

The difference is dramatic. Instead of generic data, you get actionable information that can drive business decisions, inventory management, and customer service.

🔗 Check out NicheVinDecoder on GitHub

Who This Library Is For

NicheVinDecoder isn’t trying to replace existing VIN decoders – it’s designed to complement them. It’s perfect for developers working with:

RV and Trailer Industry

  • Dealership management systems
  • Insurance applications
  • Parts lookup systems
  • Rental platforms

Specialty Vehicle Markets

  • Electric vehicle fleets
  • Industrial equipment tracking
  • Custom manufacturer databases
  • International vehicle imports

Data Integration Projects

  • Vehicle history reports
  • Fleet management systems
  • Auction platforms
  • Compliance tracking

The Technical Architecture

We built NicheVinDecoder with extensibility as the core principle. The library uses a factory pattern that automatically detects which decoder to use based on the World Manufacturer Identifier (WMI):

csharp

// Simple usage
var result = VinDecoder.Decode("58TBM0BU8P3A13051");

if (result.IsValid)
{
    Console.WriteLine($"Manufacturer: {result.Manufacturer}");
    Console.WriteLine($"Model: {result.Model}");
    Console.WriteLine($"Plant: {result.AdditionalProperties["PlantLocation"]}");
}

Each manufacturer decoder inherits from BaseVinDecoder and implements the specific VIN structure for that manufacturer. This means adding support for a new manufacturer is as simple as creating a new class and defining their VIN format.

Current Coverage and Growing

As of today, NicheVinDecoder supports six manufacturers across diverse vehicle types:

ManufacturerVehicle TypesExample ModelsHighland Ridge RVTravel Trailers, Fifth WheelsOpen Range, Mesa Ridge, Go PlayBrinkley RVLuxury Fifth WheelsModel Z, Model GAppalachian TrailersUtility TrailersCar Haulers, Equipment TrailersNine Tech (Segway)Electric ScootersA-Series, B-SeriesXPO ManufacturingCommercial TrailersDry Freight VansLoad Glide TrailersAluminum TrailersFlatbed Trailers

But here’s where it gets exciting – this is just the beginning.

🚀 Contribute to NicheVinDecoder

Real-World Impact

We’re already seeing NicheVinDecoder make a difference in production environments:

RV Dealership Systems: Dealers can now automatically populate inventory details, generate accurate listings, and provide instant vehicle history to customers.

Insurance Applications: Underwriters can access precise vehicle specifications for accurate risk assessment and premium calculation.

Fleet Management: Companies managing specialized vehicle fleets can track detailed asset information for maintenance scheduling and compliance reporting.

The Open Source Advantage

One of the most exciting aspects of NicheVinDecoder is its open-source nature. Every manufacturer decoder is built using publicly available VIN specifications, and we encourage the community to contribute.

Adding a new manufacturer is surprisingly straightforward:

  1. Research the VIN Structure: Gather the manufacturer’s VIN specification
  2. Create the Decoder Class: Implement the decoding logic
  3. Add Unit Tests: Ensure reliability with comprehensive tests
  4. Submit a Pull Request: Share your work with the community

We’ve made the contribution process as smooth as possible with detailed documentation, code templates, and examples.

A Community-Driven Future

The beauty of focusing on niche manufacturers is that there’s a passionate community behind each one. RV enthusiasts know Highland Ridge inside and out. Electric vehicle advocates understand every nuance of their chosen brands. Trailer professionals have deep expertise in their specialized equipment.

By tapping into this collective knowledge, NicheVinDecoder can grow to cover hundreds of specialized manufacturers that would never make it into mainstream VIN decoders.

Porting a PHP OAuth Spotler Client to C#: Lessons Learned

Recently I had to integrate with Spotler’s REST API from a .NET application. Spotler provides a powerful marketing automation platform, and their API uses OAuth 1.0 HMAC-SHA1 signatures for authentication.

They provided a working PHP client, but I needed to port this to C#. Here’s what I learned (and how you can avoid some common pitfalls).


🚀 The Goal

We started with a PHP class that:

✅ Initializes with:

  • consumerKey
  • consumerSecret
  • optional SSL certificate verification

✅ Creates properly signed OAuth 1.0 requests

✅ Makes HTTP requests with cURL and parses the JSON responses.

I needed to replicate this in C# so we could use it inside a modern .NET microservice.


🛠 The Port to C#

🔑 The tricky part: OAuth 1.0 signatures

Spotler’s API requires a specific signature format. It’s critical to:

  1. Build the signature base string by concatenating:
    • The uppercase HTTP method (e.g., GET),
    • The URL-encoded endpoint,
    • And the URL-encoded, sorted OAuth parameters.
  2. Sign it using HMAC-SHA1 with the consumerSecret followed by &.
  3. Base64 encode the HMAC hash.

This looks simple on paper, but tiny differences in escaping or parameter order will cause 401 Unauthorized.

💻 The final C# solution

We used HttpClient for HTTP requests, and HMACSHA1 from System.Security.Cryptography for signatures. Here’s what our C# SpotlerClient does:

✅ Generates the OAuth parameters (consumer_key, nonce, timestamp, etc).
✅ Creates the exact signature base string, matching the PHP implementation character-for-character.
✅ Computes the HMAC-SHA1 signature and Base64 encodes it.
✅ Builds the Authorization header.
✅ Sends the HTTP request, with JSON bodies if needed.

We also added better exception handling: if the API returns an error (like 401), we throw an exception that includes the full response body. This made debugging much faster.


🐛 Debugging tips for OAuth 1.0

  1. Print the signature base string.
    It needs to match exactly what Spotler expects. Any stray spaces or wrong escaping will fail.
  2. Double-check timestamp and nonce generation.
    OAuth requires these to prevent replay attacks.
  3. Compare with the PHP implementation.
    We literally copied the signature generation line-by-line from PHP into C#, carefully mapping rawurlencode to Uri.EscapeDataString.
  4. Turn off SSL validation carefully.
    During development, you might disable certificate checks (ServerCertificateCustomValidationCallback), but never do this in production.

using System.Security.Cryptography;
using System.Text;

namespace SpotlerClient
{
 
    public class SpotlerClient
    {
        private readonly string _consumerKey;
        private readonly string _consumerSecret;
        private readonly string _baseUrl = "https://restapi.mailplus.nl";
        private readonly HttpClient _httpClient;

        public SpotlerClient(string consumerKey, string consumerSecret, bool verifyCertificate = true)
        {
            _consumerKey = consumerKey;
            _consumerSecret = consumerSecret;

            var handler = new HttpClientHandler();
            if (!verifyCertificate)
            {
                handler.ServerCertificateCustomValidationCallback = (sender, cert, chain, sslPolicyErrors) => true;
            }

            _httpClient = new HttpClient(handler);
        }

        public async Task<string> ExecuteAsync(string endpoint, HttpMethod method, string jsonData = null)
        {
            var request = new HttpRequestMessage(method, $"{_baseUrl}/{endpoint}");
            var authHeader = CreateAuthorizationHeader(method.Method, endpoint);
            request.Headers.Add("Accept", "application/json");
            request.Headers.Add("Authorization", authHeader);

            if (jsonData != null)
            {
                request.Content = new StringContent(jsonData, Encoding.UTF8, "application/json");
            }

            var response = await _httpClient.SendAsync(request);

            if (!response.IsSuccessStatusCode)
            {
                var body = await response.Content.ReadAsStringAsync();
                return body;
            }

            return await response.Content.ReadAsStringAsync();
        }

        private string CreateAuthorizationHeader(string httpMethod, string endpoint)
        {
            var timestamp = DateTimeOffset.UtcNow.ToUnixTimeSeconds().ToString();
            var nonce = Guid.NewGuid().ToString("N");

            var paramString = "oauth_consumer_key=" + Uri.EscapeDataString(_consumerKey) +
                              "&oauth_nonce=" + Uri.EscapeDataString(nonce) +
                              "&oauth_signature_method=" + Uri.EscapeDataString("HMAC-SHA1") +
                              "&oauth_timestamp=" + Uri.EscapeDataString(timestamp) +
                              "&oauth_version=" + Uri.EscapeDataString("1.0");

            var sigBase = httpMethod.ToUpper() + "&" +
                          Uri.EscapeDataString(_baseUrl + "/" + endpoint) + "&" +
                          Uri.EscapeDataString(paramString);

            var sigKey = _consumerSecret + "&";

            var signature = ComputeHmacSha1Signature(sigBase, sigKey);

            var authHeader = $"OAuth oauth_consumer_key=\"{_consumerKey}\", " +
                             $"oauth_nonce=\"{nonce}\", " +
                             $"oauth_signature_method=\"HMAC-SHA1\", " +
                             $"oauth_timestamp=\"{timestamp}\", " +
                             $"oauth_version=\"1.0\", " +
                             $"oauth_signature=\"{Uri.EscapeDataString(signature)}\"";

            return authHeader;
        }

        private string ComputeHmacSha1Signature(string data, string key)
        {
            using var hmac = new HMACSHA1(Encoding.UTF8.GetBytes(key));
            var hash = hmac.ComputeHash(Encoding.UTF8.GetBytes(data));
            return Convert.ToBase64String(hash);
        }
    }
}

✅ The payoff

Once the signature was constructed precisely, authentication errors disappeared. We could now use the Spotler REST API seamlessly from C#, including:

  • importing contact lists,
  • starting campaigns,
  • and fetching campaign metrics.

📚 Sample usage

var client = new SpotlerClient(_consumerKey, _consumerSecret, false);
var endpoint = "integrationservice/contact/email@gmail.com";
var json = client.ExecuteAsync(endpoint, HttpMethod.Get).GetAwaiter().GetResult();

🎉 Conclusion

Porting from PHP to C# isn’t always as direct as it looks — especially when it comes to cryptographic signatures. But with careful attention to detail and lots of testing, we managed to build a robust, reusable client.

If you’re facing a similar integration, feel free to reach out or clone this approach. Happy coding!

🚫 Why AWS SDK for S3 No Longer Works Smoothly with .NET Framework 4.8 — and How to Fix It

In 2024, more .NET developers are finding themselves in a strange situation: suddenly, tried-and-tested .NET Framework 4.8 applications that interact with Amazon S3 start throwing cryptic build errors or runtime exceptions. The culprit? The AWS SDK for .NET has increasingly shifted toward support for .NET Core / .NET 6+, and full compatibility with .NET Framework is eroding.

In this post, we’ll explain:

  • Why this happens
  • What errors you might see
  • And how to remove the AWS SDK altogether and replace it with pure .NET 4.8-compatible code for downloading (and uploading) files from S3 using Signature Version 4.

🧨 The Problem: AWS SDK & .NET Framework 4.8

The AWS SDK for .NET (like AWSSDK.S3) now depends on modern libraries like:

  • System.Text.Json
  • System.Buffers
  • System.Runtime.CompilerServices.Unsafe
  • Microsoft.Bcl.AsyncInterfaces

These dependencies were designed for .NET Core and later versions — not .NET Framework. While it was once possible to work around this with binding redirects and careful version pinning, the situation has become unstable and error-prone.


❗ Common Symptoms

You may see errors like:

Could not load file or assembly ‘System.Text.Json, Version=6.0.0.11’

Or:

Could not load file or assembly ‘System.Buffers, Version=4.0.5.0’

Or during build:

Warning: Unable to update auto-refresh reference ‘system.text.json.dll’

Even if you install the correct packages, you may end up needing to fight bindingRedirect hell, and still not get a working application.


✅ The Solution: Remove the AWS SDK

Fortunately, you don’t need the SDK to use S3. All AWS S3 requires is a properly signed HTTP request using AWS Signature Version 4, and you can create that yourself using standard .NET 4.8 libraries.


🔐 Downloading from S3 Without the AWS SDK

Here’s how you can download a file from S3 using HttpWebRequest and Signature Version 4.

✔️ The Key Points:

  • You must include the x-amz-content-sha256 header (even for GETs!)
  • You sign the request using your AWS secret key
  • No external packages required — works on plain .NET 4.8

🧩 Code Snippet


public static byte[] DownloadFromS3(string bucketName, string objectKey, string region, string accessKey, string secretKey)
{
var method = "GET";
var service = "s3";
var host = $"{bucketName}.s3.{region}.amazonaws.com";
var uri = $"https://{host}/{objectKey}";
var requestDate = DateTime.UtcNow;
var amzDate = requestDate.ToString("yyyyMMddTHHmmssZ");
var dateStamp = requestDate.ToString("yyyyMMdd");
var canonicalUri = "/" + objectKey;
var signedHeaders = "host;x-amz-content-sha256;x-amz-date";
var payloadHash = HashSHA256(string.Empty); // Required even for GET

var canonicalRequest = $"{method}\n{canonicalUri}\n\nhost:{host}\nx-amz-content-sha256:{payloadHash}\nx-amz-date:{amzDate}\n\n{signedHeaders}\n{payloadHash}";
var credentialScope = $"{dateStamp}/{region}/{service}/aws4_request";
var stringToSign = $"AWS4-HMAC-SHA256\n{amzDate}\n{credentialScope}\n{HashSHA256(canonicalRequest)}";

var signingKey = GetSignatureKey(secretKey, dateStamp, region, service);
var signature = ToHexString(HmacSHA256(signingKey, stringToSign));

var authorizationHeader = $"AWS4-HMAC-SHA256 Credential={accessKey}/{credentialScope}, SignedHeaders={signedHeaders}, Signature={signature}";

var request = (HttpWebRequest)WebRequest.Create(uri);
request.Method = method;
request.Headers["Authorization"] = authorizationHeader;
request.Headers["x-amz-date"] = amzDate;
request.Headers["x-amz-content-sha256"] = payloadHash;

try
{
    using (var response = (HttpWebResponse)request.GetResponse())
    using (var responseStream = response.GetResponseStream())
    using (var memoryStream = new MemoryStream())
    {
        responseStream.CopyTo(memoryStream);
        return memoryStream.ToArray();
    }
}
catch (WebException ex)
{
    using (var errorResponse = (HttpWebResponse)ex.Response)
    using (var reader = new StreamReader(errorResponse.GetResponseStream()))
    {
        var errorText = reader.ReadToEnd();
        throw new Exception($"S3 request failed: {errorText}", ex);
    }
}

}
🔧 Supporting Methods


private static string HashSHA256(string text)
{
using (var sha256 = SHA256.Create())
{
return ToHexString(sha256.ComputeHash(Encoding.UTF8.GetBytes(text)));
}
}
private static byte[] HmacSHA256(byte[] key, string data)
{
using (var hmac = new HMACSHA256(key))
{
return hmac.ComputeHash(Encoding.UTF8.GetBytes(data));
}
}
private static byte[] GetSignatureKey(string secretKey, string dateStamp, string region, string service)
{
var kSecret = Encoding.UTF8.GetBytes("AWS4" + secretKey);
var kDate = HmacSHA256(kSecret, dateStamp);
var kRegion = HmacSHA256(kDate, region);
var kService = HmacSHA256(kRegion, service);
return HmacSHA256(kService, "aws4_request");
}
private static string ToHexString(byte[] bytes)
{
return BitConverter.ToString(bytes).Replace("-", "").ToLowerInvariant();
}


📝 Uploading to S3 Without the AWS SDK
You can extend the same technique for PUT requests. The only differences are:

You calculate the SHA-256 hash of the file content

You include a Content-Type and Content-Length header

You use PUT instead of GET

Let me know in the comments if you’d like the full upload version — it follows the same Signature V4 pattern.

✅ Summary
Feature AWS SDK for .NET Manual Signature V4
.NET Framework 4.8 support ❌ Increasingly broken ✅ Fully supported
Heavy NuGet dependencies ✅ ❌ Minimal
Simple download/upload ✅ ✅ (with more code)
Presigned URLs ✅ 🟡 Manual support

Final Thoughts
If you’re stuck on .NET Framework 4.8 and running into weird AWS SDK issues — you’re not alone. But you’re not stuck either. Dropping the SDK and using HTTP + Signature V4 is entirely viable, especially for simple tasks like uploading/downloading S3 files.

Let me know if you’d like a full upload example, presigned URL generator, or if you’re considering migrating to .NET 6+.

🔍 Fetching #Flickr Profile Information by #Email Using AvatarAPI

As developers, integrating rich user profile data can elevate the experience of our apps, websites, and services. Today, let’s dive into how you can fetch Flickr profile information by email using AvatarAPI, a handy service that consolidates avatar and profile data from multiple platforms — including Flickr.


Why Flickr?

Flickr remains a popular photo-sharing platform with millions of users showcasing their photography. While many apps focus on social media giants like Twitter or LinkedIn, Flickr’s unique focus on imagery and photography makes it valuable for projects centered around visual content or creative communities.


What is AvatarAPI?

AvatarAPI is an API designed to fetch user profile avatars and metadata by providing common identifiers such as emails, usernames, or social media IDs. It supports many sources, including Flickr, making it a one-stop shop for profile enrichment.


How to Fetch Flickr Profile Data via AvatarAPI

When you request Flickr profile info through AvatarAPI, the data is returned in XML format, containing a rich set of fields to help you understand the user behind the email address.

Here’s an example snippet of the raw XML you get from AvatarAPI for a Flickr profile:

xmlCopyEdit<?xml version="1.0" encoding="utf-8" ?>
<rsp stat="ok">
  <person id="12345678@N04" nsid="12345678@N04" ispro="0" is_deleted="0" iconserver="2257" iconfarm="3" path_alias="random_alias" has_stats="0" has_adfree="0" has_free_standard_shipping="0" has_free_educational_resources="0">
    <username>Dr. Random</username>
    <realname>Random Name</realname>
    <location />
    <timezone label="Random City, Random State" offset="+00:00" timezone_id="Europe/London" timezone="57" />
    <description>Random Description</description>
    <photosurl>https://www.flickr.com/photos/random_alias/</photosurl>
    <profileurl>https://www.flickr.com/people/random_alias/</profileurl>
    <mobileurl>https://m.flickr.com/photostream.gne?id=12345678</mobileurl>
    <photos>
      <firstdatetaken>2000-01-01 00:00:00</firstdatetaken>
      <firstdate>946684800</firstdate>
      <count>10</count>
    </photos>
  </person>
</rsp>

Breaking Down the XML

  • person attributes:
    • id and nsid: The unique Flickr user ID.
    • ispro: Whether the user has a pro account (1 for yes, 0 for no).
    • is_deleted: Indicates if the account is deleted.
    • iconserver and iconfarm: Used to construct the user’s avatar image URL.
    • path_alias: The user’s Flickr alias, used in URLs.
  • Child elements:
    • <username>: The Flickr username.
    • <realname>: The user’s real name, if provided.
    • <location>: Location info, may be empty.
    • <timezone>: Detailed timezone information with label and offset.
    • <description>: User’s personal description or bio.
    • <photosurl>, <profileurl>, <mobileurl>: URLs to various Flickr profile pages.
    • <photos>: Info about user’s photos:
      • <firstdatetaken>: When the user took their first photo.
      • <count>: Number of photos uploaded.

How to Use This Data

With this data, you can:

  • Display user avatars and profile links inside your app or website.
  • Show contextual user info like location and bio.
  • Highlight photography activity through photo counts and dates.
  • Personalize user experiences by leveraging timezone and locale info.

Constructing the Avatar URL

Flickr stores user icons using a combination of the iconfarm, iconserver, and nsid. The avatar URL can be built as:

bashCopyEdithttps://farm{iconfarm}.staticflickr.com/{iconserver}/buddyicons/{nsid}.jpg

For example, with iconfarm=3, iconserver=2257, and nsid=12345678@N04:

bashCopyEdithttps://farm3.staticflickr.com/2257/buddyicons/12345678@N04.jpg

Wrapping Up

Thanks to AvatarAPI’s support for Flickr, accessing rich profile data by just knowing a user’s email has never been easier. Whether you’re building a photography community platform, enhancing contact profiles, or adding social proof, the Flickr profile data returned by AvatarAPI can help bring your users’ identities to life.

Scam warning: Shaw Holdings Pte ltd

Scam warning!

TL; DR;
If you get approached by this company for investment. It’s a scam. Evidence below
https://drive.google.com/drive/folders/1s8PmzNv9YZQI_C50Tx118cqO9REkJgvu?usp=sharing

I got approached by this company, which in the exchange of 2 emails offered a $1M investment. To good to be true. With zero-due diligence. I’ve been trhough similar processes before, and expect a month’s worth of due dilligence document preparation before getting to the point of an offer.

Anyway, so I did due dilligence on them, and specifically, their director:
NRIC/FIN/Passport No. : S8838988C
Name : CHENG YONG TECK
Nationality/Citizenship : SINGAPORE CITIZEN
Address : 10 MARTIN PLACE, #17-14, MARTIN MODERN, SINGAPORE 237963

The director being involved in a bizarre mix of different companies, including immigration ( link ) , weddings, plastic surgery ( link )  , Weight loss, and engineering companies.

 Specifically, the Plastic surgery business has left lots of people our of pocket, and is connected to the other holding company;  quote “Anyway, both Dore Aesthethics and Dore Clinic are owned by Kate Holdings.The Director is Cheng Yong Teck who lives in Orchard Residences. Born in 1988.”

🔍 Fetching Adobe Profile Information by Email Using AvatarAPI

In the age of personalization and integration, being able to retrieve user profile images and basic information programmatically can be invaluable for CRMs, marketing platforms, and analytics systems. AvatarAPI provides a simple yet powerful way to fetch profile data from various providers, including Adobe, just by using an email address.

In this post, we’ll walk through how to retrieve Adobe profile details using AvatarAPI, including how to interpret the JSON response and especially the RawData payload.


📬 Making the Request

To fetch a user’s Adobe profile via AvatarAPI, you’ll need to send a POST request to:

https://avatarapi.com/v2/api.aspx

Here’s a sample request payload:

{
"username" : "demo",
"password" : "demo___",
"provider" : "Adobe",
"email" : "falecom@sergiolimabroker.com.br"
}

Replace username and password with your actual AvatarAPI credentials.


📦 Sample Response

Here’s what a successful response might look like:

{
"Name": "",
"Image": "https://mir-s3-cdn-cf.behance.net/user/276/63d4f1907178277.60f249006a140.jpg",
"Valid": true,
"City": "",
"Country": "",
"IsDefault": false,
"Success": true,
"RawData": "[{\"type\":\"individual\",\"authenticationMethods\":[{\"id\":\"google\",\"url\":\"https://adobeid-na1.services.adobe.com/renga-idprovider/social/v2/signin/google\"},{\"id\":\"password\",\"url\":null}],\"status\":{\"code\":\"active\",\"reason\":null},\"images\":{\"50\":\"https://mir-s3-cdn-cf.behance.net/user/50/63d4f1907178277.60f249006a140.jpg\",\"100\":\"https://mir-s3-cdn-cf.behance.net/user/100/63d4f1907178277.60f249006a140.jpg\",\"115\":\"https://mir-s3-cdn-cf.behance.net/user/115/63d4f1907178277.60f249006a140.jpg\",\"138\":\"https://mir-s3-cdn-cf.behance.net/user/138/63d4f1907178277.60f249006a140.jpg\",\"230\":\"https://mir-s3-cdn-cf.behance.net/user/230/63d4f1907178277.60f249006a140.jpg\",\"276\":\"https://mir-s3-cdn-cf.behance.net/user/276/63d4f1907178277.60f249006a140.jpg\"},\"hasT2ELinked\":false}]",
"Source": {
"Name": "Adobe"
}
}

🧠 Understanding the Response Fields

  • Image: URL of the profile image, typically hosted on Behance CDN.
  • Valid: Boolean indicating whether a profile was found.
  • IsDefault: Tells you whether the image is a generic placeholder or a custom user-uploaded image.
  • Success: Boolean status of the request.
  • Source: Confirms that the provider is Adobe.
  • RawData: This is a stringified JSON array with more granular details from the provider.

🔍 Deep Dive into RawData

Let’s parse the RawData field for a better understanding:

[
{
"type": "individual",
"authenticationMethods": [
{
"id": "google",
"url": "https://adobeid-na1.services.adobe.com/renga-idprovider/social/v2/signin/google"
},
{
"id": "password",
"url": null
}
],
"status": {
"code": "active",
"reason": null
},
"images": {
"50": "https://...50.jpg",
"100": "https://...100.jpg",
"115": "https://...115.jpg",
"138": "https://...138.jpg",
"230": "https://...230.jpg",
"276": "https://...276.jpg"
},
"hasT2ELinked": false
}
]

Key Elements:

  • type: Usually "individual", indicating a personal profile.
  • authenticationMethods: Shows available login methods for this Adobe account (e.g., Google, password).
  • status: Account status, with code typically being "active".
  • images: Dictionary of image sizes for the profile picture. Useful for responsive UI.
  • hasT2ELinked: Indicates whether the account is linked to two-factor authentication (T2E = Two-step or Two-element?).

🎯 Practical Use Case

If you’re building a user-facing dashboard, you can display a verified profile image directly using the Image field, and optionally allow your backend to parse RawData for more advanced logic, such as:

  • Detecting authentication methods.
  • Validating account status.
  • Choosing image resolution dynamically based on device.

Example (JavaScript):

const profileImgUrl = response.Image;
document.getElementById('avatar').src = profileImgUrl;

🧪 Pro Tip: Parsing RawData

Since RawData is a stringified JSON array, you’ll need to parse it manually:

const rawData = JSON.parse(response.RawData);
console.log(rawData[0].authenticationMethods);

✅ Conclusion

Using AvatarAPI, retrieving Adobe profile details is seamless and efficient. The rich JSON response, especially the RawData, provides developers with a powerful toolkit to enhance user profiles, drive personalization, or even verify identity with minimal effort.
