Discover and Explore APIs in SAP API Business Hub

From SAP Cloud Platform API Management, all the APIs available in SAP API Business Hub can be discovered via the Discover tab.

  • Logon to your SAP Cloud Platform, API Management account (say https://account.hanatrial.ondemand.com/cockpit).
  • Navigate to the Services tab, search for API Management service tile and click to open SAP API Management service.

 

 

  • Click on the link Access API Portal to open API Portal.

  • Navigate to the Discover from the hamburger icon

 

  • SAP API Business Hub is integrated into SAP Cloud Platform API Management and therefore all the APIs and Policy templates available in SAP API Business Hub can be easily discovered and consumed in SAP Cloud Platform API Management.
  • Click on SAP S/4 HANA Cloud tile to view all SAP S/4 HANA Cloud APIs.

  • Search and Select for Read Planned Orders APIs in SAP S/4 HANA Cloud APIs.

  • Click on Copy to copy the Read Planned Orders API into SAP Cloud Platform API Management tenant and connect it to your own SAP S/4 HANA Cloud tenant.

 

  • Enter your SAP S/4 HANA Cloud tenant host and port ( default port is 443) in Copy API wizard and click on OK to copy the selected Read Planned Orders API. This would create an API Proxy connecting the Read Planned APIs API to your SAP S/4 HANA Cloud tenant.

  • API Proxy is created by default in Undeployed state. Select Deploy action to deploy the newly copied Read Planned Orders API Proxy.

 

  • Click on the API_PLANNED_ORDERS API Proxy to test the API Proxy. Select the RESOURCES tab and click on GET operation view all planned orders from your SAP S/4 HANA Cloud tenant.
