To pass cookie information to the web service in the request, add the port to the root input group. You can configure one cookie port for the root input group. If you add a cookie port to the root input group, you can configure it as a pass-through port.

To extract cookie information from the response, add a cookie port to an output group. You can configure one cookie port for each output group.

When you project the cookie port to a web service request message, the web service provider returns a cookie value in the response message. You can pass the cookie value to another transformation downstream in the mapping, or you can save the cookie value in a file. When you save the cookie value in a file, you can configure the cookie as input to the REST Web Service Consumer transformation.
