Webchat Widget API

The API behind the Line chat widget. Use it to embed Line chat in your own front end instead of loading /widget/v1.js.

Two credentials are involved. The public key identifies the widget and is safe to ship in client code. POST /session exchanges it for a short-lived session token that authorises the rest of the conversation.

Every request is checked against the widget's allowed-domains list using the Origin header, so calls must come from a browser on an authorised domain. Requests are rate limited per visitor, per IP and per organisation.
