Use the checkoutUrl returned by POST /v2/buy or POST /v2/sell (API integration), or your constructed referral URL (Referral integration).
function openBanxaCheckout(checkoutUrl) {
window.open(checkoutUrl, '_blank', 'noopener,noreferrer');
}Opening in a new tab keeps your application visible in the background, so the customer can return to it after checkout completes.
function openBanxaCheckout(checkoutUrl) {
window.location.href = checkoutUrl;
}Use this when you prefer a full-page transition. The customer will be redirected back to your redirectUrl on completion.
When the customer finishes (or cancels) checkout, Banxa redirects them to the redirectUrl you specified when creating the order.
Banxa can append order parameters to your return URL on completion, allowing you to read the outcome without an additional API call. Contact your Account Manager to enable this for your account.
When enabled, the following parameters are appended:
| Parameter | Description |
|---|---|
orderId | The Banxa order ID |
orderRef | Banxa's internal order reference |
orderStatus | Final order status |
fulfillmentStatus | Fulfilment status of the order |
paymentStatus | Payment processing status |
identityStatus | KYC/identity status |
fiatAmount | Fiat amount in the order |
fiat | Fiat currency code |
coinAmount | Crypto amount in the order |
coin | Cryptocurrency code |
Tip: To link the customer to the Banxa order status page, append the orderRef value to your return URL — e.g. https://{partnerRef}.banxa.com/status/{orderRef}.
For the authoritative order status, use the order lookup endpoint or webhooks — do not rely solely on return URL parameters.
Set noopener,noreferrer when opening in a new tab to prevent the checkout page from accessing your window object.
async function startBanxaCheckout(orderParams) {
// 1. Create order
const response = await fetch('/api/create-banxa-order', {
method: 'POST',
body: JSON.stringify(orderParams)
});
const { checkoutUrl, orderId } = await response.json();
// 2. Store orderId for later status lookup
sessionStorage.setItem('pendingBanxaOrderId', orderId);
// 3. Redirect customer to checkout
window.open(checkoutUrl, '_blank', 'noopener,noreferrer');
}
