+## Creation workflow
 
 The creation workflow is a bit more complex than reading some data from the API, mainly because we rarely manage data via XML format. In most use cases the user is presented with a human understandable component, like a form, and the data entered is then processed. Besides we need to make sure that the XML sent to the webservice is understandable and complete.

+## Update workflow
 
 The update workflow is quite similar to the [creation workflow](/1.7/development/webservice/tutorials/6-create-resource/#creation-workflow), the main difference is that the initial input is not a blank XML but an existing one, so we use the `get()` method to get a prefilled XML, and then we can update its fields.
