One account, every app
A customer who has paid with Stack anywhere signs in to your checkout with an email code. Their balance and saved cards are already there.
Stack Docs
Let customers pay with the Stack account they already have. One email code, then one tap, in your app or on your website.
Three lines in your app
Your server creates a payment. Your app opens the Stack sheet with presentPaymentSheet.
Your webhook fulfils the order.
Card, bank and transfer
First-time customers pay by card, bank or bank transfer, and that payment creates their Stack account. Nobody is turned away for having no balance.
Your money, on request
Every payment lands in your Stack balance, net of fees. Pay it out to your bank whenever you like.
