WhatsApp Webhook API: Delivery Status & Inbound Events
If your backend only “fires and forgets,” you do not have a messaging integration — you have a hope.
Why webhooks matter
Delivery and read-adjacent statuses, failures, and customer replies arrive asynchronously. Polling burns quota and still misses races. Webhooks close the loop into orders, auth, and tickets.
Verify and acknowledge fast
Validate signatures, return 2xx quickly, and process work in a queue. Slow endpoints cause retries and duplicate side effects if you are not idempotent.
Map events to business state
Failed OTP → allow resend. Delivered shipping notice → update timeline. Inbound “cancel” → create a support task with the full transcript link.
Inbox plus API
Not every reply belongs in your CRM automation. High-touch chats should surface in a shared inbox while webhooks keep systems in sync.
