Use this endpoint to simulate a button click. Use the message_id and the button payload (found at data["card"]["buttons"][idx]) as the callback when a user clicks on a button.

This endpoint is useful when integrating buttons into your own custom app.

🚧
Button validation
The text, action, flow, data, type must be consistent with the original button constructed in your flow.

Example webhook payload containing a button

Tip: Use the button JSON as the payload
You can take the button JSON payload and use as the params of the endpoint.
