HTTP header ports represent HTTP headers in the request message. You can configure multiple HTTP header ports.
To pass header information to the web service in the request, add the port to the root input group. You can configure one HTTP header port for the root input group. If you add an HTTP header to the root input group, you can configure it as a pass-through port.
An HTTP header port has a port name and an HTTP header name. If an HTTP header name contains a character that is not allowed in a port name, enter an HTTP header name that differs from the port name. For example, you want to pass the header name "Content-Type" to the web service, but the Data Integration Service does not allow the dash character (-) in port names. Enter "Content-Type" as the HTTP header name, but enter "ContentType" as the port name.
To add an HTTP header port, right-click on the root input group and select
