Webhook not triggering on “Message: sent, received” events

Hi,
I’ve set up a webhook in Chatflow and enabled the following Webhook Events:
Message: sent, received.

When I click the “Test Webhook” button, I successfully receive the test data on my endpoint.
However, when actual messages are sent or received in the chat, the webhook does not trigger at all — no data is being sent to my webhook URL.

I’ve confirmed that:

• The webhook URL is active and working (it receives the test payload correctly).
• The webhook is enabled in Chatflow.
• The selected events are “Message: sent, received.”

Could you please check why the webhook is not firing for real message events?
Thank you!

As we have checked, we couldn’t find any WhatsApp number connected in Pabbly Chatflow. If [email hidden] is not your Pabbly account email address, please share the correct one.
