# Get a control app's model
By getting an app's model, or payload descriptions, you can see its control parameters in detail, including data types of the control node fields. With this data, you can integrate the Singular API into your app or platform.
To get a control app's model:
1. [Get the control app's app token](/rest-api/how-to-guides/get-a-control-apps-api-token.md).
2. Send a `GET` request to the endpoint for [Get a control app's model](/rest-api/api-reference/get-control-app-details/get-a-control-apps-model.md), `https://app.singular.live/apiv2/controlapps/:appToken/model` , replacing `:appToken` with the app token for your app instance.
The response should look like this:
The control app's model:
