FAQs
Do I need a static IP?
Not required for Cloud API, but your endpoint must be reachable via HTTPS.
How do I secure the webhook?
Use signature verification/verify tokens and HTTPS. Reject unverifiable requests.
Can I retry failed deliveries?
Meta may retry; you should handle idempotency. Implement your own retry/backoff for internal processing failures.
