Connect to Census

Census is a reverse ETL platform that syncs customer data from you lakehouse into downstream business tools such as Salesforce, HubSpot, and Google Ads.

You can integrate your Databricks SQL warehouses and Databricks clusters with Census.

Connect to Census using Partner Connect

To connect your Databricks workspace to Census using Partner Connect, see Connect to reverse ETL partners using Partner Connect.


Partner Connect only supports SQL warehouses for Census. To connect a cluster to Census, connect to Census manually.

Connect to Census manually

This section describes how to connect an existing SQL warehouse or cluster in your Databricks workspace to Census manually.


For Databricks SQL warehouses, you can connect to Census using Partner Connect to simplify the experience.


Before you connect to Census manually, you need the following:

  • A cluster or SQL warehouse in your Databricks workspace.

  • The connection details for your cluster or SQL warehouse, specifically the Server Hostname, Port, and HTTP Path values.

  • A Databricks personal access token. To create a personal access token, do the following:

    1. In your Databricks workspace, click your Databricks username in the top bar, and then select Settings from the drop down.

    2. Click Developer.

    3. Next to Access tokens, click Manage.

    4. Click Generate new token.

    5. (Optional) Enter a comment that helps you to identify this token in the future, and change the token’s default lifetime of 90 days. To create a token with no lifetime (not recommended), leave the Lifetime (days) box empty (blank).

    6. Click Generate.

    7. Copy the displayed token to a secure location, and then click Done.


    Be sure to save the copied token in a secure location. Do not share your copied token with others. If you lose the copied token, you cannot regenerate that exact same token. Instead, you must repeat this procedure to create a new token. If you lose the copied token, or you believe that the token has been compromised, Databricks strongly recommends that you immediately delete that token from your workspace by clicking the trash can (Revoke) icon next to the token on the Access tokens page.

    If you are not able to create or use tokens in your workspace, this might be because your workspace administrator has disabled tokens or has not given you permission to create or use tokens. See your workspace administrator or the following:


    As a security best practice, when you authenticate with automated tools, systems, scripts, and apps, Databricks recommends that you use personal access tokens belonging to service principals instead of workspace users. To create tokens for service principals, see Manage tokens for a service principal.

Steps to connect
