I am currently setting up an app to enable users to connect WhatsApp, Instagram, and Facebook Messenger. The goal is to allow users to send and receive messages directly from my app. Everything is working fine except for one issue: the webhooks for incoming messages.
To clarify, I am subscribed to various webhooks, and all of them work perfectly both when I click the "test" button and in production, except for the webhooks related to incoming messages from WhatsApp, Instagram, and Facebook Messenger. These incoming message webhooks are not working at all.
The strange part is that even when I manually click the "test" button to send a sample to my server, I do not receive anything. However, if I test other webhooks (non-incoming message ones), they work fine, and I receive the data without any issues.
How can I resolve this issue with the incoming message webhooks? Is there a problem with the app?
Thanks
