 * [Custom allocation policies](concepts-custom-allocation.md) can use the device payload to help select an IoT hub for a device or set its initial twin. For example, you may want to allocate your devices based on the device model. In this case, you can configure the device to report its model information when it registers. DPS will pass the device’s payload to the custom allocation webhook. Then your webhook can decide which IoT hub the device will be provisioned to based on the device model information. If needed, the webhook can also return data back to the device as a JSON object in the webhook response. To learn more, see [Use device payloads in custom allocation](concepts-custom-allocation.md#use-device-payloads-in-custom-allocation).
 
-* [IoT Plug and Play (PnP)](../iot-develop/overview-iot-plug-and-play.md) devices *may* use the payload to send their model ID when they register with DPS. You can find examples of this usage in the PnP samples in the SDK or sample repositories. For example, [Node.js PnP temperature controller](https://github.com/Azure/azure-iot-sdk-node/blob/main/device/samples/javascript/pnp_temperature_controller.js).

 * [IoT Central](../iot-central/core/overview-iot-central.md) devices that connect through DPS *should* follow [IoT Plug and Play conventions](..//iot-develop/concepts-convention.md) and send their model ID when they register. IoT Central uses the model ID to assign the device to the correct device template. To learn more, see [Device implementation and best practices for IoT Central](../iot-central/core/concepts-device-implementation.md).
