Hello @JoM03683 ,
The Nift integration provides a great way to engage and re-engage customers, and entice them with gift cards to non-competing businesses as a way of thanking them for purchasing from yours. I'd recommend checking out Nift's FAQ for additional details on how their system and cards work. I'd also recommend checking out this overview about Nift in our Knowledge Base.
If you need assistance troubleshooting your Nift setup, I'd recommend reaching out to thier support directly, as they're the developers of the integration.
