Whatsapp Trigger on n8n Cloud Website not working

Hello,

I am trying to use the Whatsapp trigger on n8n Cloud but no matter what I do it just doesn’t detect any message.

I have added the app id and app secret properly, the meta app has whatsapp configured properly, when I click test workflow the webhook on meta developer platform is added correctly, yet when I send a message from my phone to the test number or even when I use the Meta test, the trigger doesn’t detect anything.

I can use the whatsapp business cloud to send messages to my phone properly, but when receiving messages it doesn’t work. I have also tried using the production webhook and activating the workflow, but it still doesn’t work. I tried on 1.83.2, 1.84.0, and 1.84.1 but it still doesn’t work. (Just a note, the Whatsapp Business Cloud node to send messages doesn’t work with expressions on 1.83.2 so I had to update to beta 1.84.0)

There is no error, the trigger just doesn’t detect anything.

Please help, thank you

From my experience using whatsapp trigger recently, there can be two causes. Please check following -

  1. Check if your workflow is active?
  2. Sometimes whatsapp test number does not work properly, can you try with a different number?

If both cases doesn’t work, are you receiving any error?

Hello,
I have exactly the same problem. I indeed suspect an issue with Whatsapp test number… I can not figure out how to change it…
Meta is such complex to use…
Any help would be much appreciated

Once you go to developers.facebook.com => Go to your app => Expand Whatsapp => API Setup and there you should be able to see From and To. From is test number and if you expand To dropdown, you will see an option to manage phone numbers to add them to allowed list.
