Variable: webhookVerifyHandler

const webhookVerifyHandler: RequestHandler;

Defined in: src/webhook/meta.ts:46 

GET /webhook/meta — Meta’s verification handshake.

Remarks

Meta sends hub.mode=subscribe, hub.verify_token=<our-token>, and hub.challenge=<random>. We echo the challenge only when the token matches. Otherwise return 404 so an enumeration scan can’t distinguish a real webhook endpoint from anything else.
