With your instance deployed, redirect users to:
https://YOUR_HANDSHAKE_INSTANCE_URL/auth/HANDLER_ID/redirectWhere HANDLER_ID is either battlenet or the value passed to the optional id argument of the Battlenet() factory. (See Options below.)
Handshake will take each user through the Battle.net OAuth flow and before sending them back to you, at the URL specified by the callback_uri query parameter.
Modify your app/options.ts file to include the Battlenet() handler like so:
import { Battlenet, HandshakeOptions } from "handshake";
 
const config: HandshakeOptions = {
  handlers: [
    Battlenet({
      clientId: string,
      clientSecret: string,
    });
  ],
}
 
// ...Adapted from next-auth.
Consult the reference to learn about HandshakeOptions.
