# Deployment

This page explains how the Defendis API evolves over time: versioning guarantees, compatibility expectations, and the practices you should follow to keep production integrations stable.

## Versioning policy

Defendis uses path-based versioning. Current customer API is `/api/v1`

### Backward-compatible changes

We may introduce backward-compatible improvements without changing the version, including:

<CardGroup cols={3}>
  <Card title="Endpoints">
    Adding new endpoints.
  </Card>

  <Card title="Parameters">
    Adding new optional query parameters.
  </Card>

  <Card title="Fields">
    Adding new fields to existing responses.
  </Card>
</CardGroup>

<Info>
  For forward compatibility, ignore unknown response fields and avoid strict JSON parsing that fails on additional properties.
</Info>

### Breaking changes

Breaking changes will be introduced under a new version prefix `/api/v2`.
