+* Objects created in the Docusign platform as a result of an API call
 
 Each scenario in the sample app illustrates a different use case, such as creating an envelope from a template or creating a Connect configuration and receiving a Connect event. A scenario consists of a series of API calls. You can execute them one by one to see how each call is constructed, or you can run the entire scenario and review the results.
