Create a Target transformation in the Mapping Designer to write data to a web service application. When you select a REST V2 connection for a Target transformation in a mapping, the Secure Agent displays operation IDs specified in the swagger specification you configure in the connection. You must select an operation based on the object configured in the connection. When you want to write data that is in relational format to the web service application, the Secure Agent converts the relational data to a hierarchical format before writing to web service application.
When you configure a REST V2 target, you can select Operations on the Target tab to display the list of valid operations. The Secure Agent creates target fields based on the request message structure of the operation you select on the Target tab.
When you write data to a web service application, the Secure Agent includes all the mapped incoming fields from the source. You can add multiple input sources to write data to a web service application target object and define the primary and foreign key relationships between the input sources before you run the mapping. Each input source appears as separate group in the Field Mapping tab in the target transformation. You can define key relationships in the Field Mapping tab.
Field Mapping in a target transformation
You can map fields that are in a relational structure to the hierarchical structure used by the web service application.
On the Field Mapping tab for the Target transformation, the fields in the Target Fields appear in hierarchical format. The target fields are determined by the request message structure of the operation you select for the Target transformation.
Each source object displays as a group in the Input Fields area. You can select fields in the Input Fields area to map the fields to the request. If the input fields include multiple input groups, map the groups to the corresponding nodes in the request. Be sure to map all of the fields that you require in the request.
The following image shows an example of mapped input fields from the source file with the REST V2 target to update employee details:
