Test Webhook works but real message events are not delivered

Hi Pabbly Support,

We have a WhatsApp Business App number connected to Pabbly Chatflow using Coexistence.

The number works correctly in the WhatsApp Business mobile app and incoming messages and SMB Echo messages are visible in the Chatflow Inbox.

However, real webhook events are not being delivered to our webhook endpoint for:

• New Message Received
• Message Sent
• Message Received from WhatsApp Business App (SMB Echo)

The “Test Webhook” function works correctly and our endpoint returns HTTP 200.

We have also synced the WhatsApp number successfully.

Subscribe is disabled in the number menu.
Trying Register returns:
“Register endpoint is not available for SMB businesses.”

Could you please check/re-enable the Coexistence webhook subscription / real-time event delivery for this number?

The issue appears to be upstream because messages are visible in Chatflow Inbox, but the real webhook events are not fired.

Hello there,

Thanks for reaching out and for the detailed description.

Based on what you've shared, the most common cause for real-time events (delivered/read/failed status and incoming message events) not reaching Pabbly Chatflow is that the connected WhatsApp number is not subscribed to receive webhook events from Meta. Even when outbound/test messages work, without an active subscription Meta will not push real events back to Chatflow.

Since you are using a WhatsApp Business App number via Coexistence, the Subscribe step is mandatory. You mentioned that Subscribe is currently disabled in the number menu and that Register returns "Register endpoint is not available for SMB businesses." For SMB/WhatsApp Business App numbers the Register action is expected to be unavailable, so the key step here is the Subscribe action rather than Register.

It looks like you haven't set up your account yet. Please complete your account setup so that we can look into the issue.
