Web service mapping format
An Informatica SOAP web service contains an operation mapping. A SOAP operation mapping contains an Input transformation that parses the XML from a request message. You must add transformations to the web service mapping process the data as required by the client request.
An Informatica REST web service contains a resource mapping. The resource mapping does not read the request query. The REST resource mapping contains a Read transformation instead of an Input transformation. The Read transformation reads a data object in the Model repository to retrieve data to return to the client. By default, you do not have to add a Filter transformation or a Lookup transformation to retrieve the data based on the client query. The REST web service filters the output data after the mapping returns data.
