Which Cisco DNA Center RESTful PNP API adds and claims a device into a workflow?

The `api/v1/onboarding/workflow` API likely manages workflow definitions or statuses, but not the act of adding and claiming a *device* into a workflow.

The `api/v1/onboarding/pnp-device/import` API call in Cisco DNA Center is specifically designed to facilitate the Plug and Play (PnP) process by allowing devices to be imported and claimed into an onboarding workflow, linking them for configuration and management.

The `api/v1/onboarding/pnp-device` API might be used for general PnP device operations (e.g., listing or managing device details), but `import` specifically implies the action of adding and claiming.

The `api/v1/file/config` API is used for file and configuration management, not for the onboarding and claiming of PnP devices.
