# APIs {% hint style="warning" %} **Important Update** The fully supported API is under development and will be extended in the coming weeks and months. The previous beta API is now **deprecated**. While it remains operational for the time being, we recommend transitioning to the new API as soon as possible to take advantage of new features, improved performance, and long-term support. {% endhint %} ## Getting Started To start using the API, you will need to: * Obtain an **access token** to authenticate requests. * Learn how to navigate **error handling, pagination**, **filtering** and **sorting** to efficiently retrieve data. See the [Getting Started](https://docs.kpnthings.com/kpn-things/general-functions/apis/getting-started-with-the-api) guide for details. ## Resources: The API is organized around key resources. Each resource has its own dedicated reference page generated from the OpenAPI specification: * [Connector Bindings](https://docs.kpnthings.com/kpn-things/general-functions/apis/connector-bindings) * [Devices](https://docs.kpnthings.com/kpn-things/general-functions/apis/devices) * [Device Groups](https://docs.kpnthings.com/kpn-things/general-functions/apis/device-groups) * [Downlinks](https://docs.kpnthings.com/kpn-things/general-functions/apis/downlinks) * [Projects](https://docs.kpnthings.com/kpn-things/general-functions/apis/projects) ## Additional information * [Getting Started ](https://docs.kpnthings.com/kpn-things/general-functions/apis/getting-started-with-the-api)(authentication, pagination, filtering, sorting) * [Beta API (Deprecated)](https://docs.kpnthings.com/kpn-things/general-functions/apis/beta-api-deprecated) ## SSL certificate information The SSL server certificates of KPN Things and GRIP are signed by Sectigo and Certsign respectively.
