**Deprecated API:** All endpoints in this API are deprecated as of April 13, 2026. This API will no longer be available on August 5, 2026. During this phase, the API will continue to function as normal, however, no new updates other than security bug fixes will be made. It is not recommended to use this API. Alternatively, please use the new [CertnCentric APIs](https://centric-api-docs.certn.co/#introduction). To understand the differences between this and the new CertnCentric API, please read our [Legacy migration guide](https://centric-api-docs.certn.co/#legacy-api-migration).

This version of our API documentation is intended for our clients with Partner Accounts. This version provides information about some additional functionality that is unavailable for non-partner accounts. For non-partner clients we recommend using our **Certn API v 1.0** documentation. You can select the **Certn API v 1.0** documentation using the dropdown (top left) or navigate to [Certn API v 1.0](https://docs.certn.co/certn-api-v-1.0/).
