About this gig
Need to connect SAP with a web application, mobile app, portal, or another external system?
I develop SAP OData Services and REST APIs using ABAP for SAP ECC and S/4HANA environments.
I can help you expose SAP data, execute business actions, connect external applications, and troubleshoot existing SAP APIs.
My SAP API services include:
- OData V2 service development
- REST API development using ABAP
- SAP Gateway / SEGW services
- CRUD operations and entity handling
- SAP-to-external system integration
- JSON request and response processing
- HTTP-based integrations
- BAPI and RFC integration
- CDS-based data exposure
- APIs for SAP Fiori / UI5 applications
- API testing using Postman
- Error handling and API troubleshooting
- Existing OData / REST API enhancement and debugging
Example integration scenarios:
- SAP Web Portal
- SAP Third-Party System
- External System SAP
- SAP Master Data APIs
- Business Transaction APIs
I focus on clean ABAP implementation, proper validation, structured responses, error handling, testing, and technical documentation.
Please contact me before ordering for complex integrations or multi-system requirements so I can review the scope and confirm the right technical approach.
