Notes

  • Status: Beta
  • LINE requires a public HTTPS webhook URL.
  • LINE’s free tier allows 500 messages/month. Paid plans remove the limit.
  • The webhook URL must be verified in the LINE Developer Console.
  • LINE’s Messaging API uses POST webhooks - profClaw verifies the X-Line-Signature header.
