WhatsApp Business Cloud API C# Wrapper Library for .NET Developers

A Wrapper for Whatsapp Business Cloud API hosted by Meta.

Official API Documentation: Meta for Developers

Sell Product and Services: Product Message Configuration

Account Metrics: Account Metrics Configuration for analytics and conversation analytics

QR Code Message Management: QR Code Messages for WhatsApp Business

WhatsApp Flows: Setting up WhatsApp Flows

WhatsApp Cloud API Error Codes: Error Codes

Take note: Sending a message to a phone number format 00[Country Code] xx xx xx using the prefix 00 before the country code will make the cloud API return an invalid parameter error (#100) (Credits @Tekkharibo)

Take note: Downloading media from the generated Whatsapp media URL will require one to specify the app name and version value to be set as useragent for the download media function to work. It is included as properties for the config class. (Credits @atmtrujillo)

Capabilities

Note: This package is WIP. The capabilities of Cloud API will be reflected soon. Feel free to contribute!

Installation

PackageManager: PM> Install-Package WhatsappBusiness.CloudApi
DotNetCLI: > dotnet add package WhatsappBusiness.CloudApi

Setting yourself for successful WhatsApp Business Cloud Api integration

Before you proceed kindly acquaint yourself with WhatsApp Business Cloud Apis by going through the Docs in Meta's developer portal if you like.

Obtain a Temporary access token for the meta developers portal.
Ensure your project is running on the minimum supported versions of .Net
WhatsAppBusinessCloudAPi is dependency injection (DI) friendly and can be readily injected into your classes. You can read more on DI in Asp.Net core here. If you can't use DI you can always manually create a new instance of WhatsAppBusinessClient and pass in an httpClient instance in it's constructor. eg.

// When Dependency Injection is not possible...

//create httpclient instance
var httpClient = new HttpClient();

httpClient.BaseAddress = WhatsAppBusinessRequestEndpoint.BaseAddress;
	
//create WhatsAppBusiness API client instance
var whatsAppBusinessClient = new WhatsAppBusinessClient(httpClient, whatsAppConfig); //make sure to pass httpclient and whatsAppConfig instance as an argument

I would recommend creating WhatsAppBusinessClient using Dependency Injection. [Optional] You can use any IOC container or Microsoft DI container in your legacy projects.

// Adding Dependency Injection into legacy projects

public static IServiceProvider ServiceProvider;


// To be used in the main application startup method
void Application_Start(object sender, EventArgs e)
{
  var hostBuilder = new HostBuilder();
  hostBuilder.ConfigureServices(ConfigureServices);
  var host = hostBuilder.Build();

  ServiceProvider = host.Services;
}

void ConfigureServices(IServiceCollection services)
{
   services.AddHttpClient<IWhatsAppBusinessClient, WhatsAppBusinessClient>(options => options.BaseAddress = WhatsAppBusinessRequestEndpoint.BaseAddress);
   //inject services here
}

Registering WhatsAppBusinessClient & Set the BaseAddress -Dependency Injection Method in ASPNETCORE

Install WhatsappBusiness.CloudApi Project via Nuget Package Manager Console or Nuget Package Manager GUI.

For ASPNETCORE projects

In Program.cs add the namespace...

using WhatsappBusiness.CloudApi.Configurations;
using WhatsappBusiness.CloudApi.Extensions;

Inside ConfigureServices method add the following

WhatsAppBusinessCloudApiConfig whatsAppConfig = new WhatsAppBusinessCloudApiConfig();
whatsAppConfig.WhatsAppBusinessPhoneNumberId = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessPhoneNumberId"];
whatsAppConfig.WhatsAppBusinessAccountId = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessAccountId"];
whatsAppConfig.WhatsAppBusinessId = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["WhatsAppBusinessId"];
whatsAppConfig.AccessToken = builder.Configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["AccessToken"];
builder.Services.AddWhatsAppBusinessCloudApiService(whatsAppConfig);

Once the WhatsAppBusinessClient is registered, you can pass it and use it in your classes to make API calls to WhatsApp Business Cloud API Server as follows;

public class SendMessageController
{
	private readonly IWhatsAppBusinessClient _whatsAppBusinessClient;
	public SendMessageController(IWhatsAppBusinessClient whatsAppBusinessClient)
	{
		_whatsAppBusinessClient = whatsAppBusinessClient;
	}
	....
	//code omitted for brevity
}

Webhook Subscription

First, you need to setup the callback url and verify the token string for WhatsApp Cloud API to verify your callback url. Verification part

[HttpGet("<YOUR ENDPOINT ROUTE>")]
public ActionResult<string> ConfigureWhatsAppMessageWebhook([FromQuery(Name = "hub.mode")] string hubMode,
                                                                    [FromQuery(Name = "hub.challenge")] int hubChallenge,
                                                                    [FromQuery(Name = "hub.verify_token")] string hubVerifyToken)
{
return Ok(hubChallenge);
}

Receiving Messages

[HttpPost("<YOUR ENDPOINT ROUTE>")]
public IActionResult ReceiveWhatsAppTextMessage([FromBody] dynamic messageReceived)
{
// Logic to handle different type of messages received
return Ok();
}

Reply to Message

TextMessageReplyRequest textMessageReplyRequest = new TextMessageReplyRequest();
textMessageReplyRequest.Context = new TextMessageContext();
textMessageReplyRequest.Context.MessageId = textMessage.SingleOrDefault().Id;
textMessageReplyRequest.To = textMessage.SingleOrDefault().From;
textMessageReplyRequest.Text = new WhatsAppText();
textMessageReplyRequest.Text.Body = "Your Message was received. Processing the request shortly";
textMessageReplyRequest.Text.PreviewUrl = false;

await _whatsAppBusinessClient.SendTextMessageAsync(textMessageReplyRequest);

Verify Webhook X-Hub-Signature-256 (Credits @Tekkharibo)

[HttpPost]
public async Task<IActionResult> GetMessage()
{
    string stringifiedBody;

    string xHubSignature256 = this.HttpContext.Request.Headers["X-Hub-Signature-256"].ToString();

    using (var sr = new StreamReader(this.HttpContext.Request.Body))
    {
        stringifiedBody = await sr.ReadToEndAsync().ConfigureAwait(false);
    }

    string xHubSignature256Result = FacebookWebhookHelper.CalculateSignature(this._configuration.GetSection("WhatsAppBusinessCloudApiConfiguration")["AppSecret"], stringifiedBody);

    if (!String.Equals(xHubSignature256, xHubSignature256Result, StringComparison.InvariantCultureIgnoreCase))
        return this.Unauthorized("Invalid Signature");

    return this.Ok();
}

Verify Webhook X-Hub-Signature-256 (.NET 7 Minimal API) (Credits @sapharos)

app.Use((context, next) =>
{
	context.Request.EnableBuffering();
	return next();
});

// Validation implementation

string stringifiedBody;
string xHubSignature256 = context.Request.Headers["X-Hub-Signature-256"].ToString();
context.Request.Body.Seek(0, SeekOrigin.Begin);
using (var sr = new StreamReader(context.Request.Body))
{
	stringifiedBody = await sr.ReadToEndAsync().ConfigureAwait(false);
}
string xHubSignature256Result = FacebookWebhookHelper.CalculateSignature(_config.GetValue<string("Facebook:AppSecret"), stringifiedBody);
if (!String.Equals(xHubSignature256, xHubSignature256Result,StringComparison.InvariantCultureIgnoreCase))
{
	return Results.Unauthorized();
}

Error handling

WhatsAppBusinessClient Throws WhatsappBusinessCloudAPIException It is your role as the developer to catch the exception and continue processing in your application. The snippet below shows how you can catch the WhatsappBusinessCloudAPIException.

using WhatsappBusiness.CloudApi.Exceptions; // add this to your class or namespace

try
{	
	return await _whatsAppBusinessClient.SendTextMessageAsync(textMessageRequest);
}
catch (WhatsappBusinessCloudAPIException ex)
{
	_logger.LogError(ex, ex.Message);
}
