Hi,
As a Microsoft employee, I could schedule for free CKA and CKAD exams. But when I try to purchase one, it’s asked me payment information. Could you help me please ?
Hi @Aminatou_BOUBA welcome to our community!
@Mary_Simpkins works with our training team and may be able to better help you here 
Would training discounts be automatically applied to user accounts from an organization, or would they have to use a code or voucher?
@Aminatou_BOUBA did you use a voucher for the training course?
Hi Henry,
Thank you for the warm welcome.
When I used the voucher, it didn’t recognize it so I don’t know if it’s a special one I need.
Thank you for your support.
Kind Regards,
Aminatou BOUBA
Hi @Aminatou_BOUBA creating a training support ticket will be the best route here, because we will not be able to discuss your voucher code information publically on our forum.
You can access our training support ticketing here:

Hope this helps
Hi Henry, Ok thank you.
Have a good day 
.
Kind Regards,
Aminatou B.
