The Test Simulator

Debugging webhook endpoints usually requires sending messages on Telegram and checking remote error logs. With Botlify's built-in Webhook Test Simulator, you can simulate updates instantly inside Bot Studio.

How Simulation Works

  1. Open Bot Studio → Overview or Variables & Cron.
  2. Click Simulate /start Webhook.
  3. Botlify sends an authentic Telegram update payload to your bot's index.php script via local execution.
  4. The simulator displays the full execution output, runtime duration, memory usage, and the last 10 lines of error.log.
Inspect error.log Instantly If your bot code throws a fatal exception or uncaught error, it is recorded in error.log. The studio flags the bot card with a red alert badge so you can resolve issues immediately.
