# API versioning

**We are constantly improving our API with new features and enhancements. However, we ensure that these changes will not affect your application. If we make significant changes to an endpoint, we will release a new version of the API.**

**Current API Version: V1**

**We consider the following changes to be backward compatible:**

* Adding new endpoints to the API
* Adding new optional parameters to the request
* Changing a required parameter to optional
* Adding new properties to existing API responses
* Adding new events to webhooks (this means your webhook endpoint should handle unknown event types, for example, by ignoring them with a status 200 response)

**We will notify you by email whenever a change is made.**
