Google BigQuery is enterprise data warehouse for large-scale data analytics. You can connect Gtmhub to any table in a BigQuery dataset and create a Gtmhub entity based on in.


Gtmhub uses a service account with OAuth 2.0 authentication/authorization flow. Before you establish a connection to your BigQuery data set you need to make sure that the Gtmhub Service Account for Google API has been added to your project and assigned the necessary permissions. We recommend that you use a custom role and assign this role to the service account.

Creating a custom role in Google Cloud Platform

To create a custom role log in to your Google Cloud Platform account and navigate to the Console. Select the project where you want to create the custom role, then from the menu choose IAM & Admin > Roles

  • Click the Create Role button
  • Fill in details for the role you will be creating.
  • Add the following permissions:
  • Click the Create button.

Adding Gtmhub Service Account to Cloud Platform project

In the IAM & Admin management console go to the IAM section. Click on the Add button to add the Gtmhub Service account, then use as the user email. Finally set the custom role created earlier.

How to connect

  • In Gtmhub, navigate to Setup > Data Sources screen
  • Click the Add new data source button
  • From the Choose a connector dialog, select Google BigQuery from Databases tab

Enter the necessary information to connect to your BigQuery dataset:

  • Project ID - this is the ID of the project where your dataset lives
  • Dataset ID - this is the ID of the dataset you wish to connect to

Click on the Connect button. If Gtmhub has been granted the necessary permissions to read data from BigQuery you will be able to choose the table you want to pull data from. In this example we will use a table named employees.

Select the table you want. Then choose its sync schedule.
