The Rest API is the best way to interact with your e-shot marketing platform. The REST document provides you with details of the requests that can be made to retrieve or commit data in a simple interface (REST). It includes information on how authentication works, what type of data can be retrieved from the system, and where it’s coming from. For instance: metadata schema defines an external web page as $metadata and gives examples for all possible operations involving this tool such as GET/POST/PUT etcetera!
