VizQL Data Service Introduction


🕐 2 min read

The VizQL Data Service provides a programmatic way for you to access your published data outside of a Tableau visualization. With a viz, you perform operations like dragging a pill to rows or columns. This accomplishes two things. It fetches data from the data source, and then creates a visualization of that data.

With VizQL Data Service, you can fetch the data without any need for a visualization.

How does it work?

VizQL Data Service is a standard HTTP service with a Query data source method. You describe your data query in the request body as a JSON object.

What tools do you need?

There are many ways to make API requests. You can create your own or use existing tools like cURL and Postman. See the VizQL Data Service folder in the Tableau APIs Postman collection to help get you started.
