# Adding a New Version of a Certificate via API

## Overview

To replicate the "Add New Version" feature seen in the UI through the API, you must create a new certificate version linked to a previous certificate.

## How to Create a New Version

1. Include the `previous_certificate_id` in the FormData when creating a new certificate.
2. The system verifies that the API key owner matches the owner of the previous certificate.
3. If verified, a new certificate is created with an incremented version number.
