 This feature can be used as an enhancement for [custom allocation](https://docs.microsoft.com/azure/iot-dps/how-to-use-custom-allocation-policies). For instance, you want to allocate your devices based on the device model without human intervention. In this case, you will use [custom allocation](https://docs.microsoft.com/azure/iot-dps/how-to-use-custom-allocation-policies). You can configure the device to report the model information as part of the [register device call](https://docs.microsoft.com/rest/api/iot-dps/runtimeregistration/registerdevice). DPS will pass the device’s information into to the custom allocation webhook. And your function can decide which IoT Hub this device will go to when it receives device model information. Similarly, if the webhook wishes to return some data to the device, it will pass the data back as a string in the webhook response.
