Describe the problem/error/question

Whatsapp trigger is not working properly. I have set the developer account and set all the credentials eventhough it throws me the error.

What is the error message (if any)?

Hey @R-Soorya

Thank you for reaching out! It looks like this issue might be more of a support request rather than a bug report. For general support, troubleshooting, or questions, we recommend raising your request on our community support forum.

The forum is a great place to connect with both our team and other community members who can help out. You might even find answers to similar questions there!

As a starting point it looks like the error is coming back from WhatsApp and they are unhappy with something. I would start by making sure the webhook url is correct and that it isn't localhost

We’ll go ahead and close this issue to keep the tracker focused on bug reports. Feel free to join the conversation on the forum, and let us know if you have any further concerns or questions.

Thanks again for being part of the n8n community!
