Solved: How to use a Pub/Sub Topic as a target endpoint

christofano · 05-27-2022 01:52 PM

I am not sure if I've been doing right, but I want to call a PubSub Topic instead of a URL Endpoint.

The aim of this is validate data from a public API before send to Topic,

Could Someone help me, please!!

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.
