Messaging API reference

# Common specifications

Common specifications for Messaging API, such as the domain name of endpoints, response when a request succeeds or fails, and rate limit.

# Webhooks

When an event occurs, such as when a user adds your LINE Official Account as a friend or sends a message, the LINE Platform sends an HTTPS POST request to the webhook URL (bot server).

The webhook URL is configured for each channel in the LINE Developers Console.
