The document discusses RESTful Adapter's support for OpenAPI 2.0 specifications. It allows generating WSDL definitions from OpenAPI descriptions to enable integration with SAP Process Orchestration. The process involves configuring an OpenAPI receiver channel, generating the WSDL/XSD artifacts, and importing them into the Enterprise Service Repository. This simplifies REST API integration by eliminating the need to deal with JSON/XML transformations or configure request parameters manually.

1. RESTful Adapter + OpenAPI 2.0
Stay relevant and produtive with REST APIs

2. RESTful Adapter - stay relevant in the API age
What is Open API 2.0?
• „The“ Open API Description format
• Language agnostic API description
• Good cross language Code generation support for REST
client/servers
• Supported by all big vendors/open source contributors and
now also by SAP PO via KaTe RESTful adapter
https://www.openapis.org/

3. RESTful Adapter - OpenAPI 2.0 Support
KaTe RESTful adapter – OpenAPI 2.0 Support (v 1.0.7)
- Extends „Code Generation“ for OpenAPI to SAP PO/SAP PI*
- WSDL Generation as ESR Content
- No time spent on XML/JSON transformation
- No time spent on path configurations / headers / query attributes
- Works with extension of proven KaTe RESTful Message structures „out
of the box“
- Simply configure a receiver channel and generate the ESR
artefacts for invocation

4. How it works (3 simple steps)
• 1.) Configure the base path of your OpenAPI in a receiver
channel with „Open API“ mode + Authentication
• 2.) Generate the WSDL (or XSD‘s) for your OpenAPI
description
• 3.) Import the generated artefacts to ESR and build your
scenario (or use our Developer tools for first tests)

Summary
• Simple „1 minute“ integration of OpenAPIs
• No guess work for JSON / Paths / Parameters, ASMA‘s, simply
mapping it with our proven Metadata approach
• The „rest“ is taken care of by our adapter as it should be in a
state of the art API integration extension (XML/JSON, URIs
etc)
