Looker Integration
Connect Looker to Census and sync data directly from Looker Looks.
Census supports connecting to an existing Looker environment, which allows you to build Looker Looks with Looker's powerful visual builder and then sync the data to any of your business apps.
Census compiles your models on the fly whenever a sync is scheduled so your data and your models are always up to date. Here's a quick video of the instructions that we've covered in the write-up below.
Set up
To connect Looker to your Census instance, you'll need two things:
An existing Census data source connection that matches the data source used by Looker. See the below section on about permissions.
Looker API3 credentials for the user that has access to the Looks you plan to use in Census.
To create new API3 credentials, you'll need to visit the Admin > Users page, select the desired user and click the Edit button and then the Edit Keys button on the user's profile page. You'll need to note both the Client ID and Client Secret values to provide to Census. The Looker documentation provides more details on how to find and create keys.
You'll also need the URL of your Looker instance. You should be able to simply pull that directly from your browser URL bar. For example, if the URL is https://censususer.looker.com/ then the subdomain is censususer.
If you're using a self-hosted instance of Looker, provide the full URL as well as the port number of your API, for example https://yourlooker.yourcompany.com:443. The port number may be 443 or 19999 depending on when your Looker instance was created, or it may be another value if you've overridden the default. See Looker documentation for more details.
Connecting Census to Looker
Now back in Census, select Sources from the left navigation bar and, if you have multiple warehouse connections, click on the Projects button of the one that matches your Looker instance. Once you've clicked on Projects, pick the Looker tab. You'll see a Connect Looker button to start the process. From here, simply provide your subdomain, the client id and client secret.
Once saved, you should see all of your Looker Looks!
Note: Looks that are in development mode are not shared in the Looker API so only Looks that have been published will appear in Census.
Required data warehouse permissions
Census and Looker both maintain their own data warehouse credentials and connections which means each can have different permissions. However, Census requires the same permissions your Looker Looks use within Looker. If Census is missing some permissions that Looker has, you may see a permissions error in Census when attempting to preview the model or use it in a sync.
Unsupported features
Totals & Row Totals
Looker will autogenerate additional SQL queries when Totals or Row Totals are selected. These features are not supported for syncs from Census, and therefore the related SQL will not be imported to Census.
We will add the following as the last line of your SQL when this occurs.
