About Versioning

Latest Version


Versioning System

The API is versioned based on Semantic Versioning 2.0.0. You can request any major version number when making requests to the API and you will recieve a response from the most recent minor/patch issue within that version.

i.e. If versions 0.0.0, 0.1.0, 0.1.1, and 1.0.0 exist and you request version 0, you will recieve a response from 0.1.1.

For all versions 1.0.0 onwards, minor and patch version changes will always be backwards compatible and will not invalidate previous code which uses the API. Non-backwards-compatible updates will come in the form of major version updates and you will have to explicitly start requesting the new version once you are sure that your application is ready.

Requesting a Version

Request a version of the API by including an Accept HTTP header in the form: application/vnd.ents24.com.vX or application/vnd.ents24.com.vX+json where ‘X’ is the version number you want to request.

e.g. application/vnd.ents24.com.v1

If the Accept header is unspecified then we will serve API version 0.


Here you can find details of changes between versions of the API, in order to assist in migrating your app from one version to another.
