I am trying to figure out how to modify the ack deadline for a push subscription message. The problem is, I don't have the ack Id which is a required argument for the modify_ack_deadline function. The message which is being pushed to the endpoint doesn't seem to have the acknowledgement id in it. So my question is, how do I get a hold of this acknowledgement id if it's even possible?
There is no way to modify the ack deadline when using a push subscription. The message must be acknowledged within the subscription's configured ack deadline. If extending the ack deadline is needed, the a pull subscription must be used.
