Installation

Available via NuGet package Bot.Builder.Community.Adapters.Infobip.Messages

Install into your project using the following command in the package manager:

PM> Install-Package Bot.Builder.Community.Adapters.Infobip.Messages

Usage

Prerequisites

To use the Messages API, you need:

1. An Infobip account with Messages API access
2. API credentials (API key, base URL)
3. Configured channels (WhatsApp, SMS, etc.)
4. Webhook endpoint configuration

Contact Infobip support for account setup and channel configuration.

Configuration

You can configure the adapter using appsettings.json:

{
  "InfobipApiKey": "your-api-key",
  "InfobipMessagesApiBaseUrl": "https://api.infobip.com",
  "InfobipAppSecret": "your-app-secret",
  "InfobipMessagesApiKey": "your-messages-api-key"
}

Wiring up the Adapter

1. Create an Adapter Class

public class InfobipMessagesAdapterWithErrorHandler : InfobipMessagesAdapter
{
    public InfobipMessagesAdapterWithErrorHandler(
        InfobipMessagesAdapterOptions options, 
        IInfobipMessagesClient client, 
        ILogger<InfobipMessagesAdapterWithErrorHandler> logger)
        : base(options, client, logger)
    {
        OnTurnError = async (turnContext, exception) =>
        {
            // Log any leaked exception from the application
            logger.LogError($"Exception caught : {exception.Message}");

            // Send a catch-all apology to the user
            await turnContext.SendActivityAsync("Sorry, it looks like something went wrong.");
        };
    }
}

2. Create a Controller

[Route("api/infobip/messages")]
[ApiController]
public class InfobipMessagesController : ControllerBase
{
    private readonly InfobipMessagesAdapter Adapter;
    private readonly IBot Bot;

    public InfobipMessagesController(InfobipMessagesAdapter adapter, IBot bot)
    {
        Adapter = adapter;
        Bot = bot;
    }

    [HttpPost]
    public async Task PostAsync()
    {
        // Delegate the processing of the HTTP POST to the adapter
        await Adapter.ProcessAsync(Request, Response, Bot);
    }
}

3. Register Dependencies in Startup.cs

public void ConfigureServices(IServiceCollection services)
{
    services.AddMvc().SetCompatibilityVersion(CompatibilityVersion.Version_2_1);

    // Create the Bot Framework Adapter with error handling enabled
    services.AddSingleton<IBotFrameworkHttpAdapter, AdapterWithErrorHandler>();

    // Add dependencies for Infobip Messages Adapter
    services.AddSingleton<InfobipMessagesAdapterOptions>();
    services.AddSingleton<IInfobipMessagesClient, InfobipMessagesClient>();

    // Add Infobip Messages Adapter with error handler
    services.AddSingleton<InfobipMessagesAdapter, InfobipMessagesAdapterWithErrorHandler>();

    // Create the bot as a transient
    services.AddTransient<IBot, YourBot>();
}

Message Handling

Incoming Messages

The adapter automatically converts incoming messages to Bot Framework activities:

• Text messages ? Message activity with Text property
• Media messages ? Message activity with Attachments
• Location messages ? Message activity with GeoCoordinates entity
• Contact messages ? Message activity with contact entities
• Interactive messages ? Message activity with Value containing user selection
• Button/List replies ? Message activity with structured Value object
• Flow responses ? Message activity with flow data in Value
• Delivery reports ? Event activity with name "DELIVERY"
• Seen reports ? Event activity with name "SEEN"

Outgoing Messages

Send messages using standard Bot Framework activities:

// Text message
await turnContext.SendActivityAsync("Hello, world!");

// Message with quick reply buttons
var reply = MessageFactory.SuggestedActions(
    new[] { "Option 1", "Option 2", "Option 3" },
    "Choose an option:");
await turnContext.SendActivityAsync(reply);

// Media message
var attachment = new Attachment
{
    ContentType = "image/jpeg",
    ContentUrl = "https://docs.microsoft.com/en-us/bot-framework/media/how-it-works/architecture-resize.png",
    Name = "Bot Framework Architecture"
};
var imageMessage = MessageFactory.Attachment(attachment);
await turnContext.SendActivityAsync(imageMessage);

// Hero card (converted to appropriate format per channel)
var heroCard = new HeroCard
{
    Title = "Card Title",
    Subtitle = "Card Subtitle",
    Text = "Card description text",
    Images = new List<CardImage> { new CardImage("https://example.com/image.jpg") },
    Buttons = new List<CardAction>
    {
        new CardAction(ActionTypes.OpenUrl, "Open URL", value: "https://example.com"),
        new CardAction(ActionTypes.PostBack, "Click Me", value: "button_clicked")
    }
};
var heroCardMessage = MessageFactory.Attachment(heroCard.ToAttachment());
await turnContext.SendActivityAsync(heroCardMessage);

Callback Data

Add custom data to track messages:

var callbackData = new Dictionary<string, string>
{
    {"orderId", "12345"},
    {"userId", "user123"}
};

var activity = MessageFactory.Text("Your order has been processed!");
activity.AddInfobipCallbackData(callbackData);
await turnContext.SendActivityAsync(activity);

Retrieve callback data from delivery reports:

if (turnContext.Activity.Type == ActivityTypes.Event && 
    turnContext.Activity.Name == "DELIVERY")
{
    var callbackData = turnContext.Activity.GetInfobipCallbackData();
    if (callbackData != null)
    {
        var orderId = callbackData.GetValueOrDefault("orderId");
        var userId = callbackData.GetValueOrDefault("userId");
        // Process delivery report...
    }
}

?? Payload Format Validation

The adapter ensures all messages use the correct format with ALL CAPS for channels and content types:

{
    "messages": [
        {
            "sender": "sender-id",
            "channel": "WHATSAPP",
            "destinations": [
                {
                    "to": "user-conversation-id"
                }
            ],
            "content": {
                "body": {
                    "type": "TEXT",
                    "text": "Hello World"
                }
            }
        }
    ]
}

?? Quick Start with Sample Bot

1. Navigate to the sample directory:

   cd samples/Infobip\ Messages\ Adapter\ Sample
   

2. Update appsettings.json with your real Infobip credentials:

   {
     "InfobipApiKey": "your-actual-api-key",
     "InfobipMessagesApiBaseUrl": "https://2kdgrw.api.infobip.com",
     "DefaultSender": "sender-id",
     "EnablePayloadLogging": true
   }
   

3. Run the sample bot:

   dotnet run
   

4. Connect Bot Framework Emulator to http://localhost:5000/api/messages

5. Test commands that make real API calls:

   • "help" - Show all available test commands
   • "test whatsapp" - Send via WhatsApp with real API call and logging
   • "test sms" - Send via SMS with real API call and logging
   • "test buttons" - Interactive buttons with real API integration
   • "debug payload" - Show expected payload format
   • "status" - Show current configuration

6. Check console output for real API request/response logging:

   === INFOBIP MESSAGES API REQUEST ===
   Endpoint: https://2kdgrw.api.infobip.com/messages-api/1/messages
   Payload: {"messages":[{"channel":"WHATSAPP",...}]}
   ===================================
   

Example Test Bot Usage

// The sample bot demonstrates real library usage:

// Test different channels with real API calls
await turnContext.SendActivityAsync("Type 'test whatsapp' to send via WhatsApp");
await turnContext.SendActivityAsync("Type 'test sms' to send via SMS");
await turnContext.SendActivityAsync("Type 'debug payload' to see format");

// Check console output for payload logging:
// === INFOBIP MESSAGES API REQUEST ===
// Endpoint: https://2kdgrw.api.infobip.com/messages-api/1/messages  
// Payload: {"messages":[{"channel":"WHATSAPP",...}]}
