  Concept: Workday Query Language (WQL)

Workday Query Language (WQL) enables you to use SQL-like syntax to access Workday data using data sources and fields instead of reports. WQL enables you to query Workday for data and explore:

-   Data sources.
-   Data source filters.
-   Fields.


## <a id="d379e330"></a>Enabling WQL

To use WQL from an external system you need to register an API client for your tenant. Register it in your tenant using the <b>Register API Client for Integrations</b> task. You don't have to register an API client when you're using WQL in a Workday Extend or Orchestration app.

When you register the API client for WQL, select <i>System</i>from the <b>Scope (Functional Areas)</b> prompt.

When you manage the refresh token, select a Workday account that has access to execute reports. The API calls use this account.

## <a id="d379e351"></a>Security

To use WQL, you need access to the <i>Workday Query Language</i> domain in the System functional area. You can only view and use data sources and fields that you have security access to within a WQL query.

## <a id="d379e363"></a>WQL and RaaS Usage Metrics Report

Integration developers with security access to the <i>Manage: All Custom Reports</i> domain in the System functional area can use this report to monitor usage trends for API requests over time. The report displays WQL and Reports as a Service (RaaS) executions for outbound integrations. It returns counts for a rolling 90 days by dimensions, such as time and source of request. The report uses the <b>WQL/RaaS Usage Metrics</b> report data source.

<b>Note:</b> You can only view report results in your Production tenant.
