We apologize for the expired test data in sandbox. Our tech team is currently working to update the database. Can you please send an email to firstname.lastname@example.org to request for a working test PAN for sandbox testing? I can't share it in the public forum unfortunately. If your project is ready to be promoted to the higher environment for extensive testing, please submit a Go Live request and you will be provided with real test PANs in cert. environment. Thanks.
