Common issues

Here are some common errors and issues with the WhatsApp Trigger node and steps to resolve or troubleshoot them.

Workflow only works in testing or production

WhatsApp only allows you to register a single webhook per app. This means that every time you switch from using the testing URL to the production URL (and vice versa), WhatsApp overwrites the registered webhook URL.

You may have trouble with this if you try to test a workflow that's also published. WhatsApp will only send events to one of the two webhook URLs, so the other will never receive event notifications.

To work around this, you can disable your workflow when testing:

1. Go to your workflow page.
2. From the workflow settings dropdown, click Unpublish to disable the workflow temporarily.
3. Test your workflow using the test webhook URL.
4. When you finish testing, click Publish. The production webhook URL should resume working.
