Create a Pre-provisioning Template

Function

This API is used by an application to create a pre-provisioning template on the IoT platform. For a device not registered, you can use a pre-provisioning template to automatically register the device information on the IoT platform when the device connects to the platform for the first time.

A pre-provisioning template takes effect only after it is bound to at least one device CA certificate.
An instance can have a maximum of 10 pre-provisioning templates.
This API is supported only by standard and enterprise editions.

Debugging

You can debug this API through automatic authentication in API Explorer or use the SDK sample code generated by API Explorer.
