The onOffice API (API) processes every valid JSON document (JSON). Indentations, spaces and line breaks have no effect on the processing. To ensure the lowest possible transmission data and the avoidance of possible error sources, the response is delivered without any formatting. The response is also valid JSON.

To better illustrate the JSONs used in the API, they are indented and wrapped if necessary.
