Wild Apricot Payments/AffiniPay
AffiniPay allows users to create "tags" called "Category 1" and "Category 2" in their merchant applications that can be passed through to the AffiniPay process, thereby enabling the merchant application to share custom information about the transaction origination to AffiniPay's reporting and back to the paying customer.
However, Wild Apricot has not implemented hooks in its application to allow its clients (the "merchant") to make use of the tags feature.
It's there for the using, so please, Wild Apricot, get it working for us.
We're aware of the issue, but this is not currently possible
