I'm trying to integrate the Whatsapp Cloud API to a chatbot.
I went through the entire procedure highlighted here but whithout success: https://forum.promptchat.com/d/30-whatsapp-business-platform-fb-cloud-api-integration-to-promptchat
First of all, it is important to highlight that my app on Meta for Developers was validated, being successfully tested using the Glitch example webhook.
However, when trying to configure the Callback URL for promptchat, the Meta app does not connect. The image below shows the error when trying adding it.
As the procedure for configuring the APP was the same with the test I did on Glitch, I'm not sure if there's anything wrong I am doing in promptchat.
I appreciate some help.
