# Applications

OAuth applications let you consume the API and build your integrations. Three different types of [API credentials](https://app.gitbook.com/s/-LgByaSP8eKjad-MIuHE/api-credentials) — providing different types of API credentials — are currently available: **sales channel**, **integration**, and **webapp**.

To fully manage your applications and API credentials please leverage the [dedicated endpoint](https://app.gitbook.com/s/xrdVVavnnBMHRCqrLp1y/api-reference/api_credentials) on the Provisioning API.

{% hint style="info" %}
This is a **singleton API**, meaning that only the API credentials within the current scope are retrieved. No need to specify the resource ID. If you need to manage (programmatically or manually) all your API credentials you can leverage our [Provisioning API](https://app.gitbook.com/s/xrdVVavnnBMHRCqrLp1y/api-reference/api_credentials). This endpoint is also **immutable**, meaning that create, update, and delete operations are not allowed.
