If you understand webhooks, you can connect WA.Expert to anything. That is not an exaggeration.
Webhooks are the integration mechanism that makes WA.Expert a platform rather than just a messaging tool. Understanding them — how they work, how to design them, and how to troubleshoot them — is the single technical skill that unlocks the most advanced implementations.
The good news: webhooks are conceptually simple. Event occurs → HTTP POST request fires → receiving system acts on the data. That is the whole thing.
A webhook is a doorbell. When the button is pressed (event), an electrical signal fires (HTTP POST), and the bell rings inside (receiving system acts). You don't keep checking the door — the bell tells you when something happened. That is webhook architecture.
WA.Expert → external system
When a form is submitted in WA.Expert (chatbot input, Flow completion), WA.Expert fires a webhook to a URL you provide — delivering data as a JSON payload to your system.
External system → WA.Expert
When an event happens in your external system (new order, payment received), your system fires a webhook to WA.Expert's API, which triggers the appropriate WhatsApp message.
Payload design
JSON body should contain: event type, timestamp, unique identifier, relevant data fields. Minimise payload size — send only what the receiving system needs to act.
Error handling
Every webhook needs: retry logic (auto-retry 3x on failure), logging (every payload logged), dead letter queue (failed retries flagged for manual review). No data silently lost.
🔑 Non-coder's webhook toolkit: Make.com, Zapier, and n8n receive webhook payloads and route data between systems visually — no code required. For most client implementations, these are faster and more maintainable than custom code.

Question 1 of 5
What is a webhook in plain terms?
✅ Event → HTTP POST → data delivered to receiving URL → receiving system acts. Simple concept, very powerful application.
❌ A webhook is an event-triggered notification. Event occurs → POST fires → data arrives → receiving system acts. Conceptually simple, architecturally powerful.
Question 2 of 5
Shopify store wants every new order to trigger a WhatsApp confirmation. How does this work technically?
✅ Shopify webhook → WA.Expert API → template sent. Event-driven, real-time, zero manual intervention at any order volume.
❌ Shopify webhook → WA.Expert API → WhatsApp template is the architecture. Event-driven, real-time, no human step.
Question 3 of 5
What should a well-designed webhook payload for a WA.Expert task submission include?
✅ Event type + timestamp + unique ID + user identifier + relevant data fields. Everything the receiving system needs to act correctly. Nothing unnecessary.
❌ Minimum viable payload: event type, timestamp, unique ID, user ID, specific data fields. Keep payloads lean — only what the receiving system needs.
Question 4 of 5
A webhook fires but the receiving system is temporarily down. What should happen?
✅ Retry + dead letter queue. Webhooks without retry logic lose data during outages. Dead letter queues ensure failed deliveries are never silently dropped.
❌ Retry + dead letter queue is the production pattern. 3 retries at increasing intervals, then manual review queue. No data silently lost.
Question 5 of 5
Non-technical client wants to connect WA.Expert to Google Sheets without writing code. Recommended approach?
✅ Make.com or Zapier. No-code webhook routing that connects WA.Expert to any tool visually. Most standard integrations can be built this way in 30 minutes.
❌ Make.com or Zapier is the answer. No-code webhook routing platforms. Standard integrations without custom code — accessible to non-technical teams.
