How to use a service #
Web services created with yunIO can be integrated into all cloud applications that support REST API/Swagger (OpenAPI), e.g. Power Automate, Nintex, etc.
To test a service after creation, trigger the URL of the service endpoint under Service (1). The service is then executed in your web browser.
Note: Only services that do not require parameters supplied by a caller will display any SAP results in the browser. For parameterized services, use a tool that supports Swagger/OpenAPI definitions (e.g.Swagger Inspector, Postman) .
To integrate a yunIO web service into a tool that supports Swagger/OpenAPI, copy the code or download the service definition (2).
