Typical Use Scenarios
The KaTe RESTful Adapter for SAP Integration Suite solves the most common challenges in REST API integration with SAP – whether in the cloud, on-premise, or in hybrid environments.
Software development is increasingly shifting to mobile platforms, hyperscalers, or container environments. These rely on the Open API standard for API management, security (JWT, OAuth2), and automation.
Our adapter facilitates the integration of SAP into API-first strategies of the non-SAP world – whether in SAP BTP, with hyperscalers like AWS, Azure, or GCP, or in containerized development environments.
Regulated industries such as telecommunications (TMF), banking (Open Banking), or utilities (market data exchange) rely on standardized Open APIs. Our approach significantly reduces the development and operating costs of such APIs – while utilizing existing developer skills and requiring minimal investments.
With the KaTe RESTful Adapter, you maximize the efficiency and security of your API integrations, protect existing investments, and build seamless bridges between SAP and modern API standards – to meet the increasing demands for integrating modern technologies and drive your digital transformation forward.
SAP has strongly committed to OData over the years, which can be described via Open API definitions. However, the following challenges often arise in hybrid environments or API management solutions:
- › SAP Specifics: Clients have to deal with XCSRF token management or SAP-specific attributes.
- › Internal Links: API management solutions deliver responses with internal links, which poses security risks and makes use by OData clients difficult.
The KaTe RESTful Adapter solves these problems efficiently: Links are automatically rewritten to frontend URLs, and XCSRF tokens are processed automatically.

Discover IntegraMonFrequently Asked Questions
Answers to the most important questions about the KaTe RESTful Adapter for SAP Integration Suite.
What is the KaTe RESTful Adapter for SAP CPI?
As a powerful middleware component, the KaTe RESTful Adapter for SAP Integration Suite connects SAP systems with REST APIs according to the Open API standard. It supports OpenAPI 3.x and Swagger 2.0 and enables 1:1 migration of existing interfaces from SAP Process Orchestration – drastically reducing development times.
What advantages does the adapter offer in API development?
The adapter offers the following development advantages:
- Drastically reduced time required for JSON/XML translation and HTTP status routing
- Existing ESR objects become Open APIs with just a few clicks
- ABAP Proxies can be generated from Open API definitions (API First)
- Established frameworks like ABAP Proxy generation and monitoring can continue to be used
Is the adapter compatible with SAP BTP and hybrid landscapes?
Yes. The adapter supports OAuth2 endpoints on the public internet as well as on-premise via SAP Cloud Connector. It is fully compatible with SAP BTP, SAP Cloud Integration, and the SAP Edge Integration Cell. Hyperscalers like AWS, Azure, and GCP are directly supported.
How does security work in the RESTful Adapter?
Because security is a top priority in enterprise environments, the adapter blocks non-compliant API calls and supports:
- OpenID / JWT Authentifizierung
- Custom OAuth2 (cloud and on-premise via Cloud Connector)
- NTLM-Authentifizierung
This makes OAuth2 calls fully traceable – no black box. All authentication flows are visible in the SAP Integration Suite Monitor.
How are monitoring and debugging implemented?
All API operations and statuses are searchable and visible without overhead through automatic indexing of key/values of API operations in the SAP Integration Suite Monitor. HTTP status codes, OAuth2 flows, and API endpoints can be viewed directly in the monitor – without additional configuration.
Which SAP platforms are supported?
The KaTe RESTful Adapter runs on all current SAP platforms:
- SAP Integration Suite (Cloud Integration / CPI)
- SAP Business Technology Platform (BTP)
- SAP Edge Integration Cell (EIC) – for hybrid on-premise/cloud scenarios
- SAP Process Orchestration (PO) – via the separate SAP PO version of the adapter
How does ABAP Proxy generation work?
With the KaTe Launchpad Generator, ABAP Proxy structures can be generated directly from Open API definitions. Existing ESR objects from SAP PO can be used as a basis, so no new development is required. The generated proxies are fully compatible with SAP ABAP development environments.
How does automatic XCSRF token handling work?
SAP OData services require XCSRF tokens for write operations. The KaTe RESTful Adapter handles token management fully automatically, so OData clients can use SAP APIs without SAP-specific knowledge. Internal links are rewritten to frontend URLs in the process.
How does the installation and commissioning work?
Installation takes place in just a few steps directly in your SAP Integration Suite. After requesting the 30-day trial, you will receive access to the adapter within 48 hours. Our team will support you during onboarding, so initial productive scenarios run quickly.
What licensing models are available for the RESTful Adapter?
The KaTe RESTful Adapter is available with a 30-day free trial – after that, flexible licensing models are available. Because every corporate environment has different requirements, we would be happy to advise you individually on licensing options and prices. Contact us at info@kate-group.com.
