may I reframe that just a bit? It sounds like you want to use a pubsub url as the target url endpoint. Not “instead of” a target url. But “as” the target url.

as you know, all the resources managed under google cloud have a restful API. Connecting to a pubsub topic (publishing content to a topic!) via http is just a matter of using the appropriate url and payload. Here’s the pubsub doc to help you.

it should be like creating any other API proxy in Apigee.

there is one flourish: in Apigee x, you can use the GoogleAuthentication element to manage the authentication to the upstream pubsub endpoint. Search around for this, it will be easy to find details.
