REST APIs often include dependency constraints that restrict how two or more parameters can be combined to form valid API calls. These inter-parameter dependencies make it difficult to automatically interact with the services, since API specification languages offer little or no support for them. We carried out a study on 40 industrial APIs and found that 85% of them contain inter-parameter dependencies. More importantly, we classified all the dependencies found (over 600) into seven patterns, serving as the basis for future proposals for modeling and analyzing inter-parameter dependencies automatically.
