Backend and integration rescue
Fix WhatsApp Cloud API Webhook and Production Setup Issues
I fix contained WhatsApp Cloud API integration issues, including webhook verification failures, missing inbound messages, production setup blockers, Meta app configuration problems and unreliable message handling.
Fixed-scope engagements generally start at ₹30,000.
I work on existing systems with a clearly identifiable technical problem. I do not currently take complete application builds, staff-augmentation roles or ongoing production support.

FAQ
Questions buyers usually ask
Why does WhatsApp Cloud API webhook verification fail?
Usually the callback URL, verify token, request handling or app configuration is wrong.
Why are inbound WhatsApp messages not reaching my server?
The webhook may be misconfigured, blocked or parsing the payload incorrectly.
What permissions are needed for WhatsApp Cloud API production setup?
It depends on the exact app and number configuration; I review the required technical setup only.
Can you fix an existing WhatsApp Cloud API integration?
Yes, if the issue is contained and you can share source and environment access.
Can you investigate without production credentials?
Yes, but I will not ask for secrets through the site.
