When setting up a Promo Campaign, you may want to limit the number of Guests who are able to use the code. The Number of Guests field found on step 2 of setting up a promo campaign will restrict the number of times the promo code is allowed to be used.
In this example, the promo code will be valid for the first 600 times it is used. After that, it will be invalid for guests who attempt to use it.
If using Directly processed at POS, do note there is no way to limit the use of the promo code to one time per guest. If you'd like more control over the usage of the code, please see this guide on using the Unlock rewards on Mobile App promo setting:
How can promo code uses be limited to one use per guest?
