# Welcome

Welcome to Switch platform Developer Documentation.

{% hint style="warning" %}
**Readings are moving to the Metering API.** If you send readings through the Switch API today, see [Migrating from the Switch API](/metering-api/migrating-from-the-switch-api.md).
{% endhint %}

This documentation has everything you need to build your own integrations with the Switch platform, through the Switch API, the Metering API and the OpenADR 3 VTN API.

You can find the user documentation of the Switch app [here](https://user.switchmarket.se/).
