WhatsApp Cloud Business API Integration (.NET Core, with Use Example) | Communication Tools

WhatsApp Cloud Business API Integration for .NET Core is a developer-ready toolkit that helps you connect your apps and services to WhatsApp using the Cloud-hosted API. Ship production-grade messaging (alerts, OTPs, order updates, customer care) fast with clean C# code samples, a reusable service layer, and a plug-and-play webhook receiver. Ideal for SaaS teams, agencies, and enterprises that need reliable, scalable WhatsApp messaging in their .NET stack.

🚀 Feature Highlights

• ⚙️ Clean .NET Core SDK Layer – Typed request/response models, interfaces, and services for Messages, Media, Contacts.
• 🧩 Drop-in Webhook Receiver – Ready-made controller for message status, inbound messages & verification handshakes.
• 📲 Templates & Session Messages – Send pre-approved template messages and manage customer-care session replies.
• 🔐 Secure Auth & Secrets – Environment-based config, bearer tokens, and signature validation helpers.
• 🧪 End-to-End Use Example – Working sample app (Minimal APIs + HttpClient) with send, media upload, and webhook demo.
• 📈 Observability Hooks – Built-in logging scopes and extensible policies for retries/timeouts.
• 🌍 Production-Ready Patterns – DI-friendly, SOLID code structure, async/await, and Polly-style resilience (optional).
• 🔄 Lifetime Free Updates – Ongoing improvements under GPL; wpshop.net provides limited email support.

📜 Detailed Overview

This package shortens the path from “sandbox token” to “first production message.” You get a lightweight IWhatsAppClient abstraction, typed models for common endpoints (messages, media, contacts), a verification-ready webhook controller, and an executable sample that demonstrates sending a template message, replying within a session, and processing delivery/read events. The code is framework-agnostic across the .NET Core ecosystem (e.g., .NET 6/7/8) and follows familiar patterns (Dependency Injection, Options, HttpClientFactory) so your team can scale features without wrestling the raw HTTP surface.

🛠️ Installation Guide

1. Download the package from your wpshop.net account and extract it.
2. Open the solution in Visual Studio / Rider / VS Code (.NET 6+ recommended).
3. Configure environment variables (user secrets or appsettings.json):
   • WhatsApp:BaseUrl (Cloud API endpoint)
   • WhatsApp:PhoneNumberId
   • WhatsApp:BusinessAccountId
   • WhatsApp:AccessToken (temporary or system user token)
   • WhatsApp:VerifyToken (for webhook verification)
4. Run the sample project: dotnet run. Use the included endpoints to send a test message.
5. Expose your webhook (e.g., via HTTPS or tunneling) and register the callback URL in your app settings on the Meta dashboard.
6. Verify the webhook: when Meta calls your endpoint, respond with the challenge as implemented in the sample controller.
7. Deploy to your environment (IIS, Azure App Service, Linux containers) and plug the service into your app’s workflow (orders, OTP, alerts).

📚 Use Example (Minimal API Snippet)

// Program.cs (excerpt)
builder.Services.Configure<WhatsAppOptions>(builder.Configuration.GetSection("WhatsApp"));
builder.Services.AddHttpClient<IWhatsAppClient, WhatsAppClient>();
var app = builder.Build();

app.MapPost("/send-template", async (
    IWhatsAppClient client,
    SendTemplateRequest req) =>
{
    var result = await client.SendTemplateAsync(req);
    return Results.Ok(result);
});

app.MapGet("/webhook", (HttpRequest http, IOptions<WhatsAppOptions> opts) =>
{
    // Verification handshake
    var mode = http.Query["hub.mode"];
    var token = http.Query["hub.verify_token"];
    var challenge = http.Query["hub.challenge"];
    if (mode == "subscribe" && token == opts.Value.VerifyToken)
        return Results.Text(challenge!);
    return Results.Unauthorized();
});

app.MapPost("/webhook", async (WebhookUpdate update, ILogger<Program> log) =>
{
    // Handle inbound messages & statuses
    log.LogInformation("Webhook: {@update}", update);
    return Results.Ok();
});

app.Run();
