Data Source Access Requirements:

Before authenticating the connector, please make sure you have gone through the rights and permissions required for this data source. To learn more, please refer to these guides:

Access requirements for user account:


For Dataset, you will need both BigQuery Data Viewer and BigQuery User role levels.

For Project, you will need only a BigQuery User role level. 


  • BiqQuery Data Viewer
    When applied to a dataset, this role provides permissions to:
    • Read the dataset's metadata and list tables in the dataset.
    • Read data and metadata from the dataset's tables.
  • BigQuery User
    Provides permissions to run jobs, including queries, within the project. The user role can enumerate their own jobs, cancel their own jobs, and enumerate datasets within a project. Additionally, allows the creation of new datasets within the project; the creator is granted the BigQuery Data Owner role for these new datasets.
