How to Receive WhatsApp Events with Wawp on n8n

The Wawp Trigger node in n8n is the perfect starting point for any WhatsApp automation. It acts as a webhook that listens for real-time events from your Wawp account, allowing you to build workflows that react instantly to user actions.

Step 1: Add the Wawp Trigger Node

First, you need to add the Wawp Trigger node to the beginning of your n8n workflow.

Open Canvas Open your active n8n workflow canvas.

Search Node Search for Wawp Trigger in the available node panel inventory.

Initialize Trigger Click on the node to instantiate it directly onto your canvas.

Add Wawp Trigger Interface — **Wawp Trigger Initialization**

Required Connectivity: The webhook URL must be globally accessible via the internet. Wawp cannot send events to a local environment (localhost) link. This feature works exclusively with n8n Cloud or public-facing self-hosted instances.

Once added, open its settings container to grab your distinct endpoint identifiers:

Test URL: Dedicated unique link used strictly for temporary construction testing.
Production URL: Master live pipeline URL consumed following deployment release.

Step 2: Configure Webhook in Wawp

Define where outbound event streams should target within Wawp's administrative boundaries.

Dashboard Access Log into your official Wawp account dashboard and find your active instance.

Trigger Config Locate and click the Webhook toggle visible on your core number instance card.

Add Callback Choose Add New Webhook from the popup modal.

Inject URL Paste your explicit Production URL extracted from n8n into the endpoint input field.

Save Setup Define desired Retry Policies and subscription scopes before hitting Save.

Step 3: Verify & Active Execution

Finalize tests confirming live callback relay functionality works flawlessly.

Arm Listener Head back to n8n and hit Execute Workflow. The server now sits actively listening for input payloads.

Send Pulse Grab your smartphone and manually send a standard WhatsApp message to your tied number.

Monitor Feedback Verify the visual nodes immediately illuminate in execution green within n8n indicating valid traffic lock.

Execution Payload Visuals — **n8n Live Execution View**

Troubleshooting Alert: Should connection loops experience latency errors or rejection, navigate to the trigger node and actively disable the Respond 200 override option.

Advanced Branching Logic

The native Wawp Trigger excels as a multi-output logic distribution switch. Instead of messy redundant webhooks, one trigger efficiently routes disparate payload paths including standard chats or group joins like message and group.v2.join automatically through parallel processing channels.
