Device enroll API to be used by a device to issue an X509 certificate signed by tenant's [certificate authority](#operation/postBulkNewDeviceRequestCollectionResource). The identifier and enrollment OTP for a device must be first shared as a pre-shared-key (PSK) with Cumulocity using the [bulkNewDeviceRequests](#operation/postBulkNewDeviceRequestCollectionResource) endpoint or [NewDeviceRequests](#operation/postNewDeviceRequestCollectionResource) endpoint for certificate provisioning. Internally, ID and ENROLLMENT_OTP fields will be added to the NewDeviceRegistration list with a status of Accepted, serving as temporary device credentials for device authentication. Device re-enroll API to be used by a device to renew its certificate or replace its certificate with its current credentials (being a password or a JWT token).
