I usually get emails on my email Id which I use to schedule a certification saying - Congrats, you passed and few more details on accessing certificate, transcript, badge etc..
Anyway, please note that, Microsoft Certification / Exam related questions are currently not supported on this forum. It's better to reach out to experts in a dedicated forum over here:
