The CMSi API is a set of web services based upon the Odata open standard. It allows CMSi data to be exported and imported into other systems via a standard HTTP requests and is typically used by web sites, mobile applications or other systems that need to create, read, update or otherwise interact with CMSi data. The API is available for all plugin modules to CMSi (for example the Property and Agreements module, Observations and Vegetation module) and is part of the core CMSi system.
