# 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](/kpn-things/general-functions/apis/getting-started-with-the-api.md) 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](/kpn-things/general-functions/apis/connector-bindings.md) * [Devices](/kpn-things/general-functions/apis/devices.md) * [Device Groups](/kpn-things/general-functions/apis/device-groups.md) * [Downlinks](/kpn-things/general-functions/apis/downlinks.md) * [Projects](/kpn-things/general-functions/apis/projects.md) ## Additional information * [Getting Started ](/kpn-things/general-functions/apis/getting-started-with-the-api.md)(authentication, pagination, filtering, sorting) * [Beta API (Deprecated)](/kpn-things/general-functions/apis/beta-api-deprecated.md) ## SSL certificate information The SSL server certificates of KPN Things and GRIP are signed by Sectigo and Certsign respectively. Both certificate providers are trusted by default by most operating systems. If required for your security implementation, all certificate files of the chain can be downloaded here: * Sectigo R46 root CA: * Sectigo R36 intermediate CA: * certSIGN ROOT CA G2: * certSIGN Public Web CA: --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
