How to Test a Telegram Bot Webhook

Telegram bot webhooks are easier to debug when you first point Telegram at a public inbox, inspect update payloads, and only then connect your bot handler.

Steps

1. Create a webhook URL in WebhookPilot.
2. Register it with Telegram using setWebhook.
3. Send a message to the bot.
4. Inspect the update payload and identify the fields you need.

Example

curl "https://api.telegram.org/bot<token>/setWebhook?url=https://your-domain.com/hook/telegram-test"

Common mistakes

• Exposing a local development port directly
• Logging the entire bot token
• Assuming every update has the same shape

FAQ

Can I inspect images or files?

You can still inspect metadata, headers, and payload size even when the body is not plain JSON text.

Why use an inbox first?

It lets you understand the real update structure before writing parsing logic.

Use Webhook payload examples as a reference for common shapes.
