Hello Nurul,

Thank you for your question. According to the error message, your endpoint does not return a successful response.

Would you be able to provide an example of the response you are receiving?

Thank you!

Hello Nurul,

Thank you for your response. The error message indicates that the endpoint is not reachable or not returning any response. Otherwise, there would be an actual response or an error code.

To resolve this issue, I recommend checking if your endpoint is receiving any requests when you send a data channel request. If it is, then check if it is sending any response back.

For a step-by-step guide on how to implement your flow endpoint, please refer to the documentation: https://developers.facebook.com/docs/whatsapp/flows/guides/implementingyourflowendpoint#setup.

Thank you!

Hi Nurul, I am also working on WhatsApp flows and am stuck in a deadlock and support has also been of no use, can we connect somewhere so I can learn from your experience in working with flows?
