@Dnyaneshwar Surywanshi - Thank you for your post and I apologize for the delayed response!
Generating and submitting PIN is supposed to be a manual operation, like OTP and was primarily intended to be a portal only multi-user authentication experience. Since REST API is present, theoretically you could have SDKs generated out of it but it is not meant to be used programmatically.
May I know the end-to-end scenario that you are planning to implement?
