Hi,

My guess atm, is that you have more than one whatsapp trigger node in n8n? Can you check other workflows as this could be why.

Best regards,

Samuel

Hi I think I know the issue.

Try to run an HTTP node with the configuration below. Just replace the orange parts with your specific values. And then import with the cURL import button. It will return your active webhook. I think n8n doesn’t delete webhooks once they have been created so you need to do it yourself.

curl 'https://graph.facebook.com/<API_VERSION>/<WHATSAPP_BUSINESS_ACCOUNT_ID>/subscribed_apps' \
-H 'Authorization: Bearer <ACCESS_TOKEN>'

You can then send another http request to delete the one. And then make a new trigger.

Ok we are getting closer. So the webhook is probably gone. Make a new trigger in n8n and copy the callback url.

it gives me the error in the following image + Whats the verify token ?

OK I think I found the culprit. You have to make a new credential. The old one is n8n should be deleted and recreated.

i deleted the credintals and entered them again idont know how to solve the callback problem

Is your workflow activate and are you using the production url?

[kerolos_nader]

know i returned to the same problem

[Grot]

That is really something…

The cUrl I gave you earlier, did you run it and did it give any output? I feel like there is something missing. So just to recap, you have tried to set up a new app but it gives the same error.

To help you further I would need to test it myself. I will create a account later in the day if nobody else chimes in.

But try to run the cURL and report back with the results. I’m pretty sure it the old one isn’t deleted if facebook returns that output.
