Purpose

If an access token is not provided or expires at the time of connection, the access token generated using refresh token is used to authenticate to a Google BigQuery instance when using OAuth 2.0.

See "Generating OAuth credentials" to know how to obtain a refresh token.

Notes

  • If a value for the AccessToken property is not specified, the driver uses the value of the RefreshToken property to generate an access token to make a connection.
  • If both AccessToken and RefreshToken values are not specified, the driver cannot make a successful connection.
  • If both AccessToken and RefreshToken values are specified, the driver uses the AccessToken value. However, if the AccessToken value has expired, it uses the RefreshToken value to generate a new AccessToken value.
