Workday Graph API is for small, self-service transactions that require fetching the exact shape of complex data within a single request. Graph API's ability to consolidate what would normally require multiple REST API calls into a single endpoint significantly reduces network overhead and improves app performance.

To get started, [explore and try the queries and mutations in Workday Graph API](https://developer.workday.com/graph-api-explorer).
