TheOpen Collaboration Services (OCS) is an open and vendor-independentREST andWebDAV based API designed to make it easy to connect apps to a content collaboration platform.[1]
The OCS API provides basic file handling features such as file access, sharing, versioning and commenting. It also supports communication (chat, video calls), calendaring, tasks and more.
The OCS API allows for the integration of web communities and web-based services into desktop and mobile applications. It allows the exchange of relevant data from asocial network between the site and clients such as other websites and applications or widgets running locally on the user's machine or mobile device. The protocol is designed so that all applications can access multiple services providing OCS APIs.
The initialAPI design was done byopenDesktop.org as part of the Social Desktop, especially as a cross-desktopbackend provider.[2] The API was standardised byfreedesktop.org so that third-party providers are able to implement OCS API. Currently,Nextcloud implements and develops the OCS API, with parts also supported in various other projects and by many third party apps and tools.[3]
Non-KDE environments using the API in the past included theMaemo Downloads application store[4] and Apps forMeeGo.[5]
The OCS API documentation[6] lists several modules. Here are the key OCS modules:
The OCS API Viewer[7] is aNextcloud app where you can interactively discover APIs and try them out on your own instance from the browser.
For example, if you wanted to update a (file) share, you can go to file_sharing –> shareapi –> update a share and add the file ID. Hit “Send API request” and you can see the response from the server, and how the share was created. On top of that, it shows you code snippets for many different programming languages for executing this request.
