Enhance the SKYYVA V4 API to support the request payload CSV file format.
Now our V4/integrate rest variant supports JSON and XML as well as CSV format therefore it is possible to pass the Rest envelope XML or JSON or csv to the body of the v4/integrate. This means that for invoking the skyvva API we use only the rest variant ../services/apexrest/skyvvasolutions/v4/Integrate with either XML or JSON or CSV payload.
In the URL of V4 API, the query parameter is added in URL only.
