Hello Losant Team!

I want to know if it possible to pull a topic. I am trying to use the GCP Pub/Sub node but it seems to only work with push. I know it might seems weird trying to pull a topic but is there a solution to it?

Thanks! 🙂

Hi @Jonathan_Calderon !

While we don’t support this functionality in a native node, [GCP Pull requests](https://cloud.google.com/pubsub/docs/pull) can be made using their [API endpoint](https://cloud.google.com/pubsub/docs/reference/rest/v1/projects.subscriptions/pull) in conjunction with our [HTTP Node](https://docs.losant.com/workflows/data/http/). I would review Google’s documentation above and ensure you have credentials and parameters configured.

Let us know how it goes!

Hi again Sebastian, sorry but I was trying to use the HTTP Node with the endpoint that the documentation suggest. My problem is the credential, i have the private Key and the client Email where i must put this data in the HTTP node.  
If you can guide me again I would be very grateful.
