Is there a way to access the delivery status as a response from the Yellow.ai notification API call itself?

No, there isn't a direct way to access the delivery status as part of the response from the Yellow.ai notification API call. You need to use webhook URL to receive delivery status updates.

The delivery status is asynchronous. This means that we don't have a precise timeframe for when a message will be delivered or read. Consequently, waiting for an unknown duration is not a feasible approach to obtain the delivery status within the API call response.

If a user replies to a WhatsApp notification with quick reply buttons and triggers a flow using /quick-reply-event, will the /quick-reply-event be triggered again for subsequent quick reply interactions within the same flow?

No, the /quick-reply-event is specific to WhatsApp notifications and will only be triggered for replies to those notifications. It will not be triggered again for subsequent quick reply interactions within the same flow.
