  description: 'This Kontakt.io API provides direct access to all Kio Cloud Device Management resources. It allows integrating device administration functionality into 3rd-party applications without the need to build all underlying logic from the ground up.


    ## Authentication


    All requests must include a **JWT Bearer token** in the `Authorization` header, obtained via the [OAuth2 Client Credentials flow](https://developer.kontakt.io/docs/entity-management-integration-api/0255c5646ab01-authentication-o-auth2-client-credentials-flow).


    > **Deprecated:** The `Api-Key` header is still accepted for backward compatibility but is deprecated and will be removed. Do not use it for new integrations.


    Each API call requires the `Accept` header with the API version. **By default, set to the current stable version:** `application/vnd.com.kontakt+json;version=10`
