# Versioning

How the ComplyAdvantage Mesh API is versioned

A new version of an API endpoint is released whenever a new *backwards incompatible* change is released.

## Backwards-compatible changes

We consider the following changes as backwards compatible:

* New API endpoints
* Addition of a response body where none was present before
* Addition of optional or read-only fields/properties
* Rearrangement of fields in the JSON structure
* Incorporation of new HTTP headers
* Adding new values to an enum
* Integration of additional HTTP methods into existing resources
