Each API Call will return in a Response Object, unimportant, if the Call was successfull or not or to which API Section it belongs. The Response Object will consist of a Metadata Part, a Data Part (for Single Items and Item List Calls) and an optional Paging Part (for Item List Calls only).
Every successfull API Call will have a "result" Object, that contains the Result for this Call. Technically, there are three different API Types, who all return slightly different Result Types.
Please notice, that we cannot outline the concrete Structure of each API Call. As the Concept of Streamtypes and Output Modifiers makes it impossible to create an exhausting Description of every possible Result Data Set.
An API Call for a single Media Item, for example
/videos/byid/123. The Result Data will be an Object, which represents the Media Item.
An API Call for a list of Media Items, for example
/videos/all. The Result Data will be an Array, which represents the Media Item.
An API Call, that produces an Object within nexxOMNIA. This may be a Call to the Management API, but also Interaction Calls operate like this. In this Case, the Result Data will only consist of a Status String and mostly some Details of the created Object (for example, the ID of a new Comment).
