Efficient Integration and Development of REST APIs with SAP CPI and Open API Standard

The KaTe RESTful Adapter significantly reduces development times and operational costs when creating or utilizing REST APIs based on the Open API Standard in conjunction with SAP PO or SAP CPI.

Benefits of the RESTful Adapter for SAP CPI:

Development Benefits:

• Efficient Data Processing: Automates the creation and translation of data structures, API routing, status codes, and XML/JSON conversion.
• State-of-the-Art API Standards: Supports OpenAPI 3.0 and Swagger 2.0 for comprehensive API descriptions in sender and receiver channels.
• ABAP Integration: Simplifies the generation of ABAP classes or reuse of existing interfaces from PO ESR for backend service implementation in SAP.
• Quick and Efficient: Works seamlessly with your existing tools with minimal effort.
• Seamless Integration: Simplifies the connection of cloud, on-premise, and hybrid systems to efficiently streamline business processes.
• Easy Migration: APIs can be migrated from SAP PO to SAP CPI/Integration Suite effortlessly (±1-2 minutes per API).
• Flexibility and Scalability: Ideal for building flexible integration architectures with SAP CPI or SAP Integration Suite.

Security Benefits:

• Protection Against Unauthorized Access: Blocks non-compliant API calls.
• Flexible Authentication: Supports integration with enterprise-specific identity management solutions and provides additional authentication methods like NTLM, custom OAuth2, or JWT.

Business Benefits:

• Cost Savings: Reduces development costs by shortening development times and utilizing existing skills.
• Sustainable Investments: Reuse ESR content as Open APIs to preserve existing investments.
• No Complex Custom Development: Avoids time-consuming custom programming.

API-First Development: Bridging Old and New Worlds

Software development is increasingly shifting to mobile platforms, hyperscalers, or container environments, all of which leverage the Open API Standard for API management, security (JWT, OAuth2), and automation.

The KaTe RESTful Adapter facilitates seamless SAP integration with API-first strategies from non-SAP ecosystems—whether on SAP BTP, hyperscalers like AWS, Azure, or GCP, or in containerized development environments.

OData Support

SAP has strongly committed to OData, which can be described via Open API definitions. However, challenges often arise in hybrid environments or API management solutions:

• SAP Specifics: Clients need to manage XCSRF tokens or deal with SAP-specific attributes in OData definitions.
• Internal Links: API management solutions may return responses with internal links, creating security risks and hindering OData clients from working directly.

The KaTe RESTful Adapter resolves these issues efficiently: Links are automatically rewritten to frontend URLs, and XCSRF tokens are handled automatically.

Regulated industries such as telecommunications (TMF), banking (Open Banking), or utilities (market data exchange) require standardized Open APIs for data exchange. Our approach significantly reduces the development and operational costs of such APIs while leveraging existing developer skills and requiring minimal investment.

The KaTe RESTful Adapter maximizes the efficiency and security of your API integrations, protects existing investments, and builds seamless bridges between SAP and modern API standards. With this future-proof solution, you are well-equipped to meet the increasing demands of integrating advanced technologies and driving your digital transformation forward—enhancing your SAP landscape to its full potential.
