One-time payments let you charge a customer a single fixed amount. No recurring billing, no subscription logic. The customer pays, gets access, and that’s it.
Onetimepayment

​
How It Works

When a customer completes a one-time checkout, Suby:
1

Processes the payment

The payment is collected across the customer’s chosen method — card, bank, Apple Pay, Google Pay, or stablecoin.
2

Calculates taxes

Applicable taxes are calculated and collected automatically based on the customer’s location.
3

Delivers access

Access is granted based on your configured integration, PayLink, API, Discord, or Telegram.
4

Fires a webhook

A payment.succeeded event is sent to your server if you have a webhook configured.

​
