# Tooling API Changed Calls and Resources

These resources are new or have changes.

## Changed REST Resources

Filter Test Discovery API results by test category

Make a GET request to the existing `/services/data/v66.0/tooling/tests` resource.

The new query parameter is `category`. Existing categories are `apex` and `flow`.

Previously, you could filter tests only by namespace prefix and test method visibility. Filtering by test category is helpful in orgs with large test suites across different namespaces.")
