Hello JP, The architecture for push subscriptions does not seem to require such a magic URL as the in case of UrlFetch, as there is no user-configurable firewall involved in the delivery path. "The Pub/Sub server sends any messages for your subscription to the webhook address you have configured. " In other words the firewall you have in mind would not affect your webhook directly. You can read more related detail on the "Push Subscriber Guide" documentation page <https://cloud.google.com/pubsub/docs/push>, "Receiving Push Messages" subtitle.
To directly reply to your question, the architectural use of a webhook makes extra firewall configuration unnecessary, in this case. -- You received this message because you are subscribed to the Google Groups "Google App Engine" group.
