You can access your business objects and Workday data using Graph API queries and mutations within your Extend app. Submit the queries and mutations within your app by calling the [Graph API endpoint](/wcp_docs/flw1653707569144.html) in pages and orchestrations. When you deploy an Extend app containing business objects, they are automatically added to the Graph API schema, enabling you to submit queries and mutations with your app's business objects.
