When you configure a Source transformation, select the REST V2 connection and choose an operation to represent a web service source.
You can select an operation for the source through the connection. Configure the request message using the request message template. You can parameterize the input values in the request XML. Configure the paging attributes.
You can view the response structure in the field mapping. When you map the elements from the response structure to the output fields, the Secure Agent creates the output groups, along with the primary and foreign keys for the field names. When you deploy the mapping in a
task and run the task, the Secure Agent reads the data from web service.
