WhatsApp Webhook, Made Simple.
Go from setup to receiving your first real-time WhatsApp notification in minutes. We handle the WhatsApp webhook complexity of deliverability, security, and scalability, so you can focus on your code.
What is a WhatsApp Webhook?
In very simple language, a WhatsApp webhook is a way for the WhatsApp Business Platform to send real-time data to an application when specific events occur, such as receiving a new message or a message status change.
Instead of an application constantly "polling" WhatsApp for updates, the platform automatically sends an HTTP notification to a URL, making the process more efficient. This allows for real-time automation, such as instantly storing incoming messages in a database or triggering automated replies.
The 3 Steps of WhatsApp Webhook Delivery
Here's exactly what happens from the moment a user sends a message to when your application receives the webhook notification.
Step 1: WhatsApp Event Occurs
A user sends a WhatsApp message to your business number. The WhatsApp Cloud API immediately captures this event and prepares to notify your application.
Step 2: SendZen Processes & Secures
SendZen receives the event, verifies the signature to ensure authenticity, filters based on your preferences, and queues it for reliable delivery with automatic retry mechanisms.
Step 3: Delivered to Your Endpoint
Your application receives the verified webhook payload in real-time. You can now process the message, trigger automations, or update your database, all within milliseconds of the original event.

Get Real-Time WhatsApp Events, Instantly.
The WhatsApp Webhook provided by Facebook is the foundation of interactive messaging. Instead of constantly asking the API for updates, WhatsApp pushes notifications to your application in real-time as events happen.
Think of it this way: It's like getting a text message the moment it arrives, instead of checking your mailbox every 5 minutes.
Incoming Messages
Triggered when a new message arrives from a user. Supports text, media, and interactive messages.
Auto-response or chatbot logic
Delivery Status
Real-time updates on message delivery status. Track when messages are sent, delivered, and read.
Analytics or CRM sync
Template Status
Notifications when WhatsApp template approval status changes. Stay informed about template updates.
Manage campaign templates
Error Events
Alerts when message delivery fails. Get notified immediately when issues occur for quick resolution.
Retry or fallback mechanisms
The Complete WhatsApp Webhook API Toolkit for Developers.
Building webhooks is more than just an endpoint. A basic endpoint might work for a test, but production-grade webhooks require a surprising amount of infrastructure to get right. We built the infrastructure developers deserve-reliable, secure, and ridiculously easy to integrate.
Zero-Config WhatsApp Webhook Setup
Your WhatsApp webhook URL is automatically configured and secured the moment you complete the WhatsApp Embedded Signup. No manual WhatsApp webhook setup in the Meta dashboard needed.
Guaranteed Delivery with Automatic Retries
Deploy with confidence. If your endpoint is temporarily unavailable, we'll keep trying to deliver the notification for up to 24 hours with exponential backoff.
Powerful Filtering & Flexible Endpoints
Reduce noise and server load. Choose exactly which events you want to receive (e.g., only incoming messages) and direct them to any URL.
Developer Dashboard with Event Logs
Full visibility into your webhook activity. Inspect payloads, view delivery attempts, and replay any event with a single click for easy testing and debugging.
Built for Builders, By Builders.
With clean SDKs and predictable payloads, integrating our WhatsApp webhook API is a joy, not a chore. Get WhatsApp webhook examples in PHP, Python, Node.js, and more.
Verified, Secure, and Reliable
Your data deserves protection, every webhook is signed, verified, and encrypted.
HTTPS Only
All webhooks use encrypted HTTPS connections to ensure data integrity and confidentiality.
HMAC SHA256 Signature
Each payload is signed with HMAC SHA256 to verify authenticity before processing.
GDPR Compliant
No data logging by default. Full compliance with privacy regulations and data protection standards.
Monitor and Debug in Real Time
View delivery logs, replay failed events, and monitor webhook health, all from a single dashboard.
Webhook Activity Logs
Complete history of every webhook delivery with timestamps, status codes, and response times.
Filter & Search
Filter by event type, response code, or date range to quickly find what you're looking for.
Replay Events
Resend any webhook event to your endpoint with a single click for testing and debugging.
Webhook Fanout: SendZen provides webhook fanout to multiple endpoints, allowing you to send the same event to multiple destinations simultaneously. This enables you to trigger automations accordingly. For example, you can send events to n8n, Zapier, or any other workflow automation tool.
