SecurePayAPI

Smarter payments for modern merchants. Accept cards from customers around the world, with a checkout built around how your business actually works.

You focus on your product — we'll handle getting you paid. Spin up a payment in a single API call, then let customers pay through a polished drop-in widget or a branded hosted page. Card security and 3-D Secure authentication come built in, so the hard parts are handled for you.

These docs take you from your first test payment to a live checkout your customers trust. Onboard in days, not months — no tricks, no surprises.

How it works

Three steps, and most of the work is already done for you:

1. Create a payment on your server with your secret key — you get back a client_secret.
2. Collect the card in the browser using the embedded widget or a hosted checkout page.
3. Authentication and settlement happen automatically; you're notified of the result.

Your server is always the source of truth for the amount — the browser never decides what a customer is charged.

What you can build

Whatever fits your business — the same building blocks cover all of it:

• A custom checkout on your own pages using the embedded widget.
• A hosted page per product, shareable as a link.
• A catalog of products with prices, coupons and images you manage from your dashboard.

Before you start

You'll need a SecurePayAPI merchant account and a pair of API keys. Create your account, then grab your keys from the Developer section — see API keys for how to use them.
