When you create a Source transformation, configure an XML request message for the operation that you want to perform in the web service application.

Use the

Request Message Editor

to create a request message. The request message is in XML format. You can use the sample request message for the operation and then customize the request message to specify the data that you want to enter into the data flow.

To customize your request, copy the request message from the sample template to the

Request Message Editor

pane where you can edit the XML message and add the attributes for the request. Remove unnecessary and empty tags from the request message to avoid operation failure.

If you have not defined the request body or parameters in the OpenAPI specification, the request message template displays a static field named Request_Port. Copy the request message from the sample template to the

Request Message Editor

pane where you can edit the XML message and add the attributes for the request.

Header fields, path parameters, and query parameters appear as fields in source, target, midstream transformations.
