Authentication

You can configure the Service Account authentication method to access Google BigQuery. Select the Service Account authentication method and configure the authentication-specific parameters.
Service Account authentication requires, at a minimum, your Google BigQuery service account email, service account key, and project ID.
The following table describes the basic connection properties for Service Account authentication:
Property
Description
Service Account Email
Required. The client_email value from the Google service account key JSON file.
Service Account Key
Required. The private_key value from the Google service account key JSON file.
To use the private key from the JSON file, enter the entire block of text found within the double quotation marks in the private_key field, starting with -----BEGIN PRIVATE KEY-----\n and ending at -----END PRIVATE KEY-----\n.
Project ID
Required. The project_id value from the Google service account key JSON file.
If you have created multiple projects with the same service account, enter the ID of the project that contains the dataset that you want to connect to.
Note: If you want to validate the credentials for the Service Account Email, Service Account Key, and Project ID fields when you test the connection, set the flag CredentialValidation:true in the Provide Optional Properties field under advanced settings.
