This area of CiviCRM code and documentation is a work-in-progress. Not all features
will be documented and the core code underlying this area may change from version
to version.
The Order API is intended to be used as the primary API for adding, updating, and deleting orders.
An 'order' is a non-CiviCRM term that corresponds to how CiviCRM uses its contribution object in terms of handling the full life-cycle of a purchase of memberships, event registrations or making a donation. Unlike most APIs, there is no table directly associated with the Order API.
