You will instantly be able to use Alipay, Apple Pay, or Google Pay in KodyPay if you already have them on your phone. Provided they're available on your device, KodyPay will detect their presence, meaning you don't need to worry about adding them manually.
If any aren't automatically there, you can activate them in the KodyPay app's settings. Once added, you can simply select your preferred payment method when checking out via KodyPay.
