WhatsApp Business API Debugging

I need an experienced developer to jump into my existing WhatsApp Business API setup, trace whatever is blocking it, and get everything flowing smoothly again. At the moment the integration is unreliable—sometimes messages never leave, delivery callbacks stall, and the API connection occasionally drops. I’m looking for someone who can isolate the root cause, patch the code or server configuration as needed, and prove stability with real-world tests.

To keep us aligned, here’s what I expect you to hand over:

• Fully functional send-and-receive cycle verified with test numbers
• Webhook events firing consistently for all message statuses
• Clean, well-commented code or configuration notes outlining the fix
• Quick guide summarising any credentials, endpoints, or tokens I must refresh

You may work in the language or framework of your choice—as long as it works with Meta’s current Business Cloud API specs—and can run on my cloud host. Please outline your relevant experience with WhatsApp Business API, signal how soon you can begin, and tell me roughly how long the full diagnostic and repair should take.
