Zest supports two primary payment processors:
Stripe (recommended): The most commonly used option, suitable for most brands. Stripe powers credit card payments, Apple Pay, Google Pay, and ACH Direct Debit.
Adyen: Fully supported as an alternative for brands that require it. Brands provide their API credentials (Merchant Account, Checkout API Key, Client Key) and Zest renders the Adyen payment module at checkout.
Other processors like Authorize.net have direct integrations available for some configurations.
Square, PayPal, and Chase Payment Toolkit are not supported.
