LINE

LINE Messaging API Webhook

The inbound event surface of the Messaging API, published by LINE as an OpenAPI type-definition document. LINE delivers CallbackRequest envelopes to the bot server's configured HTTPS endpoint, carrying an events[] array of 20+ polymorphic event types (message, follow, unfollow, join, leave, postback, beacon, accountLink, membership, videoPlayComplete and others) over 60 component schemas. Every delivery is signed with a Base64 HMAC-SHA256 of the raw body in the x-line-signature header.
