CustomAllocationDefinition

This tells DPS which webhook to call when using custom allocation.

Name Type Description
apiVersion

string

The API version of the provisioning service types (such as IndividualEnrollment) sent in the custom allocation request. Minimum supported version: "2018-09-01-preview".
webhookUrl

string

The webhook URL used for allocation requests.

DeviceCapabilities

Device capabilities.

Name Type Default value Description
iotEdge

boolean

False

If set to true, this device is an IoTEdge device.

EnrollmentGroup

Enrollment group record.

Name Type Default value Description
allocationPolicy enum:
  • custom
  • geoLatency
  • hashed
  • static

The allocation policy of this resource. This policy overrides the tenant level allocation policy for this individual enrollment or enrollment group. Possible values include 'hashed': Linked IoT hubs are equally likely to have devices provisioned to them, 'geoLatency': Devices are provisioned to an IoT hub with the lowest latency to the device.If multiple linked IoT hubs would provide the same lowest latency, the provisioning service hashes devices across those hubs, 'static' : Specification of the desired IoT hub in the enrollment list takes priority over the service-level allocation policy, 'custom': Devices are provisioned to an IoT hub based on your own custom logic. The provisioning service passes information about the device to the logic, and the logic returns the desired IoT hub as well as the desired initial configuration. We recommend using Azure Functions to host your logic.
