Follow the quickstart- 1
Create a sandbox account
Sign up with your work email. The sandbox has every product and local method, and nothing in it moves real money.
- 2
Get your test keys
Copy your publishable key for the browser and your secret key for your server. Keep the secret key out of client code and version control.
- 3
Create an order on your server
An order holds the amount, currency, items and destination. We use it to pick methods, quote duties and route the payment.
- 4
Render Checkout Components
Mount the checkout with the order's client secret. It shows the right methods, language and duty-inclusive total for the shopper.
- 5
Handle the order.paid webhook
Fulfil from the webhook, not the browser redirect. Verify the signature, respond quickly, and process the event idempotently.
API playground
Pick an endpoint, edit the request body and send it. Responses are mocked in your browser, with realistic latency and status codes.
POST /v1/orders
Create an order for a cross-border purchase. The response includes a client_secret for the browser.
