API’s returning the proper data values and understanding how to consume APIs can be a daunting task. Familiarity with the technical aspect of the applications used to support API’s will greatly reduce the time spent refactoring your application. Anypoint Exchange (also called WashU API Portal), and Postman are the two applications you will use to achieve that goal.
Integrators will also require a strong understanding of the data, what it means, and how to manipulate it in order to build a successful integration.
The Help Document page will provide that context. It separated by Technical and Functional documentation.
