New account

TIP
  • When creating an account with restricted access, you must provide at least one of your topic name or subscription name. Authentication will fail if both values are missing.
  • Once created, you cannot change the authentication type of a Google PubSub base connection. To change the authentication type, you must create a new base connection.

If you are creating a new account, select New account, and then provide a name and an optional description for your new PubSub account.

The new account interface for the Google PubSub source in the sources workflow

The PubSub source allows you to specify the type of access that you want to allow during authentication. You can set up your account to have either project-based authentication or topic and subscription-based authentication. Project-based authentication allows you to grant access to the root-level project in your account, while topic and subscription-based authentication allows you to restrict access to a particular PubSub topic and subscription.

To create an account with access to your root PubSub project folder. Select Google PubSub authentication credentials as your authentication type and provide your project ID and credentials. When finished, select Connect to source and then allow some time for the new connection to establish.

NOTE
Principal (roles) assigned to a PubSub project are inherited in all of the topics and subscriptions created inside a PubSub project. If you want a principal (role) to have access to a specific topic, then that principal (role) must also be added to the topic’s corresponding subscription as well. For more information, read the PubSub documentation on access control.
