Hi @Vangarah ,
Please ensure that your organization is a partner of ServiceNow to get the CSA voucher without any cost.
If org is partner and still not showing in Voucher section then raise a case from Now learning.
If org is not a partner then you need to purchase the voucher either with learning credits or credit card.
If my response has resolved your query, please consider giving it a thumbs up and marking it as the correct answer!
Thanks & Regards,
Sanjay Kumar
