Consume Remote Services in a Full-Stack CAP ApplicationConsume Remote Services in a Full-Stack CAP ApplicationExtending the Developer's Guide application with a remote S/4HANA service — connectivity, importing the Business Partner API, and running against it. SAP publishes this as four separate paths: mock server or real S/4HANA Cloud, times Cloud Foundry or Kyma. One entry covers all four, because the difference between them is which backend and which runtime, not what you learn.SAP
Extend SAP SuccessFactors on SAP BTP with the SAP Cloud Application Programming ModelExtend SAP SuccessFactors on SAP BTP with the SAP Cloud Application Programming ModelTwelve tutorials, about two hours, building a side-by-side extension of SuccessFactors on BTP. The spine is remote services: importing the SuccessFactors OData service definitions into a CAP model, then treating them as entities the extension reads and writes through, rather than as an API called from a handler. Indexed as one entry because the parts only make sense in order.SAP

Add MCP capabilities to a CAP serviceAdd MCP capabilities to a CAP serviceA fifteen-minute walkthrough of turning a plain CAP service into an MCP server: annotate the service with @mcp, install @cap-js/mcp, and it is served alongside OData at /mcp/<path>. The part worth reading it for is what happens next — cds watch writes the endpoint into the local agent's own configuration file, so OpenCode or Claude Code can call the service without anyone editing JSON by hand. It is built on the tiny-sample facet, so there is nothing to prepare, and it shows the protocol traffic rather than only the result. Written while the adapter was in beta, and it says so.published 2026-08-13

Build a Business Application Using CAP for JavaBuild a Business Application Using CAP for JavaThe Java counterpart to the Node.js path — eight tutorials, around two and a half hours, from a generated project to a running service. Worth having indexed separately rather than folded in with the Node.js one: the runtimes diverge most in exactly the places a first application touches, and following the wrong path is a slow way to find that out.SAP

Develop a Full-Stack CAP Application Following SAP BTP Developer's GuideDevelop a Full-Stack CAP Application Following SAP BTP Developer's GuideThe eight-part path SAP's own Developer's Guide prescribes: a CAP service, Fiori Elements over it, custom logic, authorization, tests, and the preparation deployment needs. It is the closest thing to an official answer to 'what does a whole CAP application look like', which is why it sits under reference applications rather than under any one of the capabilities it touches.SAP
