Using OAuth Authentication
Use the OAuth authentication standard to connect to Google Analytics. You can authenticate with a user account or a service account. The adapter facilitates this as described below.
Using a User Account to Authenticate to Google Analytics
The user account flow requires the authenticating user to interact with Google Analytics via the browser.
Embedded CredentialsSee Embedded Credentials to connect with the adapter's embedded credentials and skip creating a custom OAuth app.
Instead of connecting with the adapter's embedded credentials, you can register an app to obtain the OAuthClientId and OAuthClientSecret.
When to Create a Custom OAuth AppCreating a custom OAuth app is optional as the adapter is already registered with Google Analytics and you can connect with its embedded credentials. You might want to create a custom OAuth app to change the information displayed when users log into the Google Analytics OAuth endpoint to grant permissions to the adapter.
Using a Service Account to Connect to Google Analytics
Service accounts have silent authentication, without user authentication in the browser. You can also use a service account to delegate enterprise-wide access scopes to the adapter.
You need to create an OAuth application in this flow. You can then connect to Google Analytics data that the service account has permission to access. See Custom Credentials for an authentication guide.
Creating a Custom OAuth App
See Creating a Custom OAuth App for a procedure.
