You can choose one of 2 options for your voucher links. You should consider how you plan to distribute the voucher links and how many people will receive them.
A general voucher link is one shared link that can be used by multiple people.
Use a general link when you’re sending one communication to a large group or printing the voucher link on a flier. You can limit the total number of vouchers when you set up your program.
A unique voucher link can be used by only one person.
A unique link works best when you’re distributing the vouchers to specific people. It provides the best visibility and control over usage.
