The POST /{{envID}}/flowExecutions/{{flowExecutionID}} operation creates a FIDO2 platform device. This operation uses the application/vnd.pingidentity.device.create+json custom media type as the content type in the request header, and the request specifies a device type, rp.id, and rp.name in the request body. The nickname property is optional.
