Hi @JosephKa2
Ultimately your integration needs to be updated to use OAuth Server-to-Server credentials. There are two ways to get there -
Route#1 Directly migrate to OAuth Server-to-Server credentials in the next 30 days
This is a viable route and will not involve creating a new certificate pair. However, make sure you can complete the migration before your existing certificate expires. (per the email you received)
Route#2 First refresh the certificate to give yourself more than 30 days, and then migrate to OAuth Server-to-Server credentials by Jan 27, 2025
This option is preferable if you cannot complete the migration before the existing certificate expires.
Both these approaches will avoid any integration downtime.
Thanks
