Working with Meta webhooks (WhatsApp / Instagram / Facebook) is a different kind of challenge.
Meta allows only one webhook endpoint per app per product, and that single endpoint has to handle many different events—messages, delivery updates, status changes, and more.
The complexity isn’t just in processing the events, it’s in the setup across different platforms:
🔹 Facebook Page webhooks can be tested in a dev mode right away.
🔹 Instagram requires switching to live mode before the webhook becomes active.
🔹 WhatsApp demands advanced access before you can even start testing with real numbers.
Each platform plays by its own rules.
To build a reliable system, I had to:
✅ Host a dedicated server to inspect real-time webhook calls.
✅ Log and analyze every incoming request from each platform.
✅ Create a flexible routing logic that cleanly separates and processes every event in real time.
It’s a perfect example of how backend work isn’t just writing APIs—it’s about orchestrating different requirements into one seamless flow.
