CX Pay API

Getting Started

Start accepting payments with CX Pay in under 10 minutes.

What is CX Pay?

CX Pay is a payment API with hosted checkout. You create a session, we handle the payment page, and you get a webhook when the money lands. No frontend payment forms, no PCI scope.

Alpha access — you're one of our first merchants. If something feels off, tell us. We'll fix it fast.

The 30-second version

1. POST /checkout-sessions  →  you get a URL
2. Redirect your customer   →  they pay on our hosted page
3. Webhook fires            →  you fulfill the order

That's the entire integration.

What you'll need

  • API Key ID and Secret — your account manager will provide these
  • A webhook endpoint — a URL on your server that can receive POST requests
  • 10 minutes — seriously, that's it

Next steps

  1. How It Works — understand the payment lifecycle (2 min read)
  2. Authentication — set up HMAC signing
  3. Webhooks — receive payment notifications
  4. Create Checkout Session — the main endpoint you'll use

How It Works

The payment lifecycle from checkout to cash — big picture first, then details.
