To obtain credentials, you will need the following:
  • Project Id
  • Service Account Private Key JSON
As you can see below, Alloy will need this information to make queries to your Pub/Sub instance. You’ll want to copy/paste that information in Alloy once you have it. In this guide, we’ll explore how to obtain these keys.

How to get the Service Account Private Key JSON

First things first, if you don’t have a service account yet, create a service account following Google’s Documentation here. Then follow the steps in Google’s Documentation here on how to create a private key in JSON format. See sample below showing how a private key in JSON format looks like.
