Start here
New to Push Cash? Begin with the Quickstart in order to create an API key and start processing simulated payments in the sandbox environment. From there, Card Payments is the foundation of most integrations.Build your integration
The core integration guides cover everything needed to accept and pay out money. Start with Card Payments; the others layer on additional payment methods and the asynchronous updates that keep your system in sync.Card Payments
The core flow end to end: register a user and collect their card, authorize a transaction, handle authentication, and retrieve the result. Includes details on enabling stored credentials, withdrawals, and refunds.
Webhooks
Receive signed, asynchronous notifications of final payment results so your transaction state stays accurate and reliable.
Apple Pay
Let users pay from your web cashier with the cards in their Apple Wallet, authorized with Face ID or Touch ID.
ACH Save
Recover eligible declined card transactions by retrying them over ACH through an authenticated bank flow.
Card Payments and Webhooks form the core of most integrations. Add Apple Pay and ACH Save as your product needs them.
