5. Click on the + Add another role button, click on Select a role. In the Filter box that appears type "BigQuery Data Viewer", then select BigQuery Data Viewer from the list that appears (gives view access to  datasets).

A file with the private key will be downloaded to your computer.

1. In Totango, click Settings from the left nav.
2. Expand Data Management > Customer Data Hub.
3. From the list of active connectors (left), choose Data Warehouses.
4. From the list of available connectors, hover over Google BigQuery, and click Connect (or View Integrations).
   
5. Enter a name and description for the connection (e.g., Company DWH - Customer and Contacts Data). Because you can have multiple connections with a connector (using different authentication profiles), a name and description helps you identify the connection later.
6. Upload the key file that you downloaded in the previous section.
7. Click Test and Save Connection.

You can now set up an integration using the connection.

All data warehouse connectors support SSL encryption. By default, Totango uses SSL encryption during connecting. If the data warehouse server does not support SSL encryption, the connection will use an unencrypted connection to stream data from the data warehouse.
