Telegram Bot API (С#)

Bot%20API .NET%20Standard NuGet

Typed .NET client for the Telegram Bot API. The library targets .NET Standard 2.0 and uses System.Text.Json for request and response contracts.

Installation

dotnet add package Endfix.Telegram.BotAPI

Features

  • strongly typed Bot API methods, parameters and response models;
  • polymorphic JSON serialization for Telegram union types;
  • JSON and multipart/form-data requests;
  • local file uploads, Telegram file IDs and attach:// references;
  • long polling and webhook examples;
  • unit tests for serialization and transport contracts.

Initialization

Each bot is given a unique authentication token when it is created. Store the token in User Secrets or an environment variable; do not put it in appsettings.json or source control. You can learn about obtaining tokens and generating new ones in this document.

var api = new BotApiClient(
    "<token>",
    new HttpClient(new SocketsHttpHandler { PooledConnectionLifetime = TimeSpan.FromSeconds(5), MaxConnectionsPerServer = 10 }) { Timeout = TimeSpan.FromMinutes(5) }
);

Examples

The example projects include placeholder configuration files. Replace the placeholders locally or use User Secrets before running them.

Download file

Use this method to get basic information about a file and prepare it for downloading. For the moment, bots can download files of up to 20MB in size.

var message = await api.SendDocumentAsync(chatId: 1234567890, document: new InputDocumentFile("path to file"));

var file = await api.GetFileAsync(fileId: message.Document!.FileId);

var fileBytes = await api.GetFileBytesAsync(filePath: file.FilePath!);

File.WriteAllBytes("path to downloaded file", fileBytes);

Tests

Run the local test suite with:

dotnet test Telegram.BotAPI.sln

Telegram integration tests are disabled unless their environment variables are configured. They can send real messages and are intended for a dedicated test bot and chat.

Status

The project follows the Telegram Bot API release it targets. The public API may change when Telegram adds or revises API methods and types.
