How it works

With your instance deployed, redirect users to:

https://YOUR_HANDSHAKE_INSTANCE_URL/auth/HANDLER_ID/redirect

Where HANDLER_ID is either line or the value passed to the optional id argument of the Line() factory. (See Options below.)

Handshake will take each user through the LINE OAuth flow and before sending them back to you, at the URL specified by the callback_uri query parameter.

Options

Modify your app/options.ts file to include the Line() handler like so:

import { Line, HandshakeOptions } from "handshake";
 
const config: HandshakeOptions = {
  handlers: [
    Line({
      clientId: string,
      clientSecret: string,
    });
  ],
}
 
// ...

Adapted from next-auth.
