How can I keep the WhatsApp Trigger Node continuously listening for events?

Below is some insight regarding the continuous activation of the WhatsApp Trigger node:

Single Registered Webhook Limitation

WhatsApp allows only one registered webhook per app. When you switch between testing and production (or vice versa), WhatsApp overwrites the previously registered webhook URL. So even if your workflow is set to active, if you run a test, the webhook registration may switch, causing the node to listen only once or only for the last registered URL.

Recommended Workaround

To keep receiving events continuously from WhatsApp in production:

1. Avoid Switching Modes:
   Do not toggle between test and production URLs. Once your workflow is active in production mode, avoid clicking on “Test Workflow.” Instead, let the production webhook handle the events continuously.

2. Disable Workflow When Testing:
   If you need to test, temporarily disable your production workflow so that your testing webhook is the sole receiver. After finishing your tests, re-enable production mode. This avoids conflicts where WhatsApp might send events to the wrong (or an overwritten) webhook URL.

3. Ensure Proper Configuration:

   • If you are on a self-hosted server, verify that your public URL (set via the WEBHOOK_URL environment variable) is correctly configured and uses HTTPS, as required.
   • For cloud-hosted instances, ensure that your credentials and configuration steps are followed as per the WhatsApp Trigger node documentation.

Summary

Because WhatsApp only supports a single webhook URL per app, using the “Test Workflow” button can override your production configuration. For seamless continuous listening, keep your workflow active solely under production mode and avoid frequent mode switching.

Hope this helps in getting your WhatsApp Trigger node to stay ready for incoming events continuously!
