Authenticate via OAuth Authentication
Use the OAuth authentication standard to connect to Google BigQuery. You can authenticate with a user account or with a service account. A service account is required to grant organization-wide access scopes to the adapter. The adapter facilitates these authentication flows as described below.
Authenticate with a User Account
Authenticate with a Service Account
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. See
Creating a Custom OAuth App in the Getting Started section to create and authorize an app. You can then connect to Google BigQuery data that the service account has permission to access.
After setting the following connection properties, you are ready to connect:
• InitiateOAuth: Set this to GETANDREFRESH.
• OAuthJWTCertType: Set this to "PFXFILE".
• OAuthJWTCert: Set this to the path to the .p12 file you generated.
• OAuthJWTCertPassword: Set this to the password of the .p12 file.
• OAuthJWTCertSubject: Set this to "*" to pick the first certificate in the certificate store.
• OAuthJWTSubject: Set this to the email address of the user for whom the application is requesting delegate access. Note that delegate access must be granted by an administrator.
• OAuthJWTIssuer: In the service accounts section, click Manage Service Accounts and set this field to the email address displayed in the service account Id field.
• DatasetId: Set this to the Id of the dataset you want to connect to.
• ProjectId: Set this to the Id of the project you want to connect to.
When you connect the adapter completes the OAuth flow for a service account.
1. Creates and signs the JWT with the claim set required by the adapter.
2. Exchanges the JWT for the access token.
3. Saves OAuth values in OAuthSettingsLocation to be persisted across connections.
4. Submits the JWT for a new access token when the token expires.
