I keep getting an error with the Telegram trigger. I created the bot correctly, as everything works fine on other services. Please help me solve this problem. When I run the trigger test, this error keeps popping up and I can't continue the process.

Here are the main reasons this happens and how to fix it:

1. Your webhook URL must be HTTPS and publicly accessible

  • Telegram only accepts HTTPS URLs with a valid SSL certificate.

  • Localhost (http://127.0.0.1:xxxx) or non-HTTPS endpoints won’t work.

  • Check that your Railway app is deployed and running, and the URL in the error (https://primary-production-…up.railway.app/webhook…) is accessible in a browser.

Try opening that exact link in your browser — you should see at least some response. If it 404s or times out, Telegram will reject it.

2. Only one webhook per bot

  • If you previously set a webhook for the same bot (maybe in another service), Telegram won’t overwrite it unless you explicitly reset it.

  • Run this in a browser (replace <BOT_TOKEN> with yours):

https://api.telegram.org/bot<BOT_TOKEN>/deleteWebhook

Then retry setting it up in your Railway trigger.

3. Correct format of the webhook endpoint

  • Telegram requires the endpoint to be just a URL, no query string weirdness, no fragments.
    Example:

    https://your-app.up.railway.app/webhook/<BOT_TOKEN>

  • Some automation platforms auto-generate a webhook path. Make sure your server actually handles POST requests at that path.

4. Bot token in the right place

  • Make sure your Railway environment variables include BOT_TOKEN, and that your code (or the trigger config) is inserting it correctly.

  • If the token is missing, Telegram might see the webhook as malformed.

Quick test to verify your webhook URL
Run this in your browser or curl (replace with your bot token & URL):

https://api.telegram.org/bot<BOT_TOKEN>/setWebhook?url=https://your-app.up.railway.app/webhook

If Telegram responds with {"ok":true,"result":true,"description":"Webhook was set"} → then your URL is valid.
