Hi @Shalabh Agarwal​ when you gave the exam? mostly it will take max of 24 hours to get the credentials in the wallet as per my previous experiences. If it is more than that, then raise a ticket using the link https://www.databricks.com/company/contact .Choose "Training Course and Certification" under the "Contact Reason" section and provide the detailed explanation in the "Message" section and submit the ticket.
