API Reference

Frontend-Only Checkout Flow

Launch a Paystrator checkout with zero backend code. This flow securely initializes a session (CSRF), creates a checkout session, and redirects customers to The Hosted Checkout Page - all from your page.


When to use

  • You want the fastest path to accept payments.
  • You don’t (yet) have a server or SDK integration.
  • You’re fine with customers completing payment on a hosted page.

How it works (at a glance)

  1. Your page loads a tiny client script.
  2. The script initializes CSRF (cookies/credentials).
  3. On Pay, it creates a checkout using your inputs (amount, description, optional payment type).

    If type isn’t specified, the hosted page shows all available methods for your account; if only one is available, it’s auto-selected.

  4. The browser redirects to the hosted checkout page.

Choose your path

  • Checkout Form – you control the inputs (amount, description, type) with a small HTML form.
  • Checkout Button – one line of HTML renders a “Pay Now” button where the script sits.
