# REST endpoint setup

* When retrieving data from a REST endpoint, a Data Point entity (non persistent entity) and the attribute(s) are required.

* Create an export mapping which specifies how the entity relates to the JSON.

* Create a rest API which returns the Http response.

* Then publish the API.
