With OutSystems, integration is easy. Developers manage the configurations of integration without the need to write custom code, significantly reducing time and effort and eliminating errors. Integration with SOAP and REST services and SAP systems is built in, and OutSystems generates all the methods and data structures to integrate with the external system. Developers can then use them visually in the application logic. From a developer's perspective, there is almost no difference between invoking an OutSystems method, a REST API, or an SAP BAPI.
