ID: Nexaweb Studio automatically assigns a restRequest ID as restRequest, with a suffix incremented by one for each additional request of this type created. (Except on The Web Services Request Configuration tab.) Keep the assigned ID or specify your own. Nexaweb Studio uses this ID to identify this restRequest in the nexaweb-webservices.xml file and to identify the dataRequestDefinition in the nexaweb-data.xml file that references this restRequest. Method: Click the arrow in the Method selection box to select an HTTP method for this restRequest to execute, if any. If you do not specify a method, Nexaweb Studio uses the GET method by default. |
