A package for effortlessly bootstrapping Telegram Bots in .NET WebAPI projects.
Supports both Polling and WebHook workflows with a unified interface and minimal configuration.

• Easy Setup: Register all bot services with a single extension method for IServiceCollection.
• Unified Handler Base: Implement your bot logic by inheriting from TgBotPlayUpdateHandlerBase, handling only the events you care about.
• Flexible Connection Methods: Switch between Polling and WebHook modes by changing an option—no code changes required.
• Automatic Reflection-based Event Subscription: Only the handler methods you implement are subscribed—no manual registration.
• WebAPI Integration: Out-of-the-box API endpoints for Telegram WebHook, configurable controller route and name.
• Health Checks: (If implemented in your project) for bot and webhook status.
• Customizable Options: Easily customize polling intervals, webhook refresh intervals, endpoint URLs, and security.

Install the NuGet package:

dotnet add package TgBotPlay.WebAPI

Create a class that inherits from TgBotPlayUpdateHandlerBase and override only the update handlers you need:

public class MyBotHandler : TgBotPlayUpdateHandlerBase
{
 public MyBotHandler(ILogger<MyBotHandler> logger) : base(logger) { }
 protected async Task OnMessage(Message message)
 {
 // Handle incoming messages
 }
 protected async Task OnCallbackQuery(CallbackQuery query)
 {
 // Handle callback queries
 }
}

Available handler methods include:

• OnMessage(Message message)
• OnEditedMessage(Message message)
• OnChannelPost(Message message)
• OnEditedChannelPost(Message message)
• OnBusinessConnection(BusinessConnection connection)
• OnBusinessMessage(BusinessMessage message)
• OnEditedBusinessMessage(BusinessMessage message)
• OnDeletedBusinessMessages(DeletedBusinessMessages messages)
• OnMessageReaction(MessageReaction reaction)
• OnMessageReactionCount(MessageReactionCount reactionCount)
• OnInlineQuery(InlineQuery query)
• (and more—see base class for the full list)

builder.Services.AddTgBotPlay<MyBotHandler>(options => options
 .WithToken("telegram bot token")
 .AsPollingClient()
 // Customize other options as needed
);

TgBotPlay automatically sets up controller endpoints for receiving updates:

• POST TgBotPlay/ — Main webhook endpoint for Telegram updates
• POST TgBotPlay/HookUp — Start webhook service
• POST TgBotPlay/HookDown — Stop webhook service

The controller route and endpoint name can be customized using WithController(...) in options (Defaults to TgBotPlay).

• Polling: .AsPollingClient()
• Webhook: .AsWebHookClient("<host name(ex. https://xyz.com)>")

No other code changes are required!

• WithController(string name, string template) — Customize controller name and route template.
• WithPollingInterval(double seconds = 5d) — Set polling interval in seconds.
• WithWebHookRefreshInterval(double minutes = 60d) — Set how often webhook is refreshed.
• SetDropPendingUpdates(bool dropPendingChanges = false) — Set how pending messages are processed when bot starts.

You can simply add TgBotPlay Health Checks like this in your Program.cs or Startup.cs:

builder.Services.AddHealthChecks()
 .AddTgBotPlayHealth();

• Reflection-based Handler Registration:
  Only the update handler methods you implement in your handler class are registered for Telegram events.
• WebHook Management:
  WebHook endpoints are exposed via ASP.NET controllers and can be invoked for health and lifecycle management.
• Automatic Dependency Injection:
  All dependencies are provided via DI; simply inject what you need in your handler or controllers.
• Proper Scope Management: Proper scopes are created and managed for webhook and polling workflows internally.

builder.Services.AddTgBotPlay<MyBotHandler>(options => options
 .WithToken("telegram bot token")
 .AsWebHookClient("host name(ex. https://xyz.com)")
 .WithController("TgBotPlay", "TgBotPlay/[action]")
 .WithWebHookRefreshInterval(30) //minuets
);

builder.Services.AddTgBotPlay<MyBotHandler>(options => options
 .WithToken("telegram bot token")
 .AsPollingClient()
 .WithPollingInterval(5) //seconds
);
