The following section gives a general introduction to working with yunIO. The information described in the following section is a prerequisite for all subsequent sections.

Starting yunIO #

To access the yunIO Designer, enter the designer-URL in a web browser.
The URL pattern to access the yunIO Designer is http://[host]:[port]. Example: http://localhost:8077.

  • If the yunIO service runs on a local server, replace [host] with localhost.
  • If the yunIO service does not run on the same machine as the browser, replace [host] with the name or IP address of the host on which the service runs.
  • After the installation the yunIO Designer is accessible under the default port 8077.
    You can configure the port under Settings in the yunIO Designer.

Note: Make sure that the yunIO service is running and that the default port 8077 is not blocked by your firewall.

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).
