The {@code DfpUser} class contains all needed information toauthenticate a user as well as generate a valid service for that user. The way in which a service is generated is performed as:
DfpUser user = new DfpUser(email, password, networkCode, applicationName);
ServiceInterface service = user.getService(DfpService.version.serviceName);
The interface {@code Interface} should match that described by{@code DfpService.version.serviceName} or else a{@code ServiceException} will be thrown. For example, if you wished toget the service {@code InventoryService} and you referenced this service by{@code DfpService.v201308.INVENTORY_SERVICE}, your import of {@code InventoryServiceInterface} should be from the package{@code com.google.api.ads.dfp.v201308}.
