The REST API is included in Camunda’s pre-built distributions.It can be accessed via the context /engine-rest and uses the engines provided by the class BpmPlatform.

The default process engine is available out of the box by accessing /engine-rest/engine/default/{rest-methods}or simply /engine-rest/{rest-methods}. Any other shared (i.e., it is globally visible) process engine that is created later is available through /engine-rest/engine/{name}/{rest-methods} without any further configuration.

Authentication is deactivated by default, but can be activated as described in the Authentication section.
