In the reward wizard, choose the approved categories (for example Swag, Food, Amazon, gift cards — or all merchants). Already sent? Open the reward and use "Edit categories" — changes apply to every recipient immediately.

Recipients see the approved categories on their reward. Purchases outside them are declined at the merchant — the most common confusion is "the merchant isn't approved" versus "the merchant is approved but the balance is too low", both shown in the decline reason on their transaction ("Why was my transaction declined?").

If your organization has turned off gift cards, Amazon, or the Perk Card entirely, those options stay hidden regardless of the categories a reward allows — see "What can my team spend on?" in your organization settings.
