JavaScript Example: Processing a Payment {#uc-getting-started-cs-js-payment-example}
====================================================================================

Payment is initiated when `Unified Checkout` captures the customer's payment information by calling the `unifiedPayment.complete()` function and passing the transient token. IMPORTANT

> If you are updating an existing ` Unified Checkout ` configuration to use the complete mandate, you must update your JavaScript to include the unifedPayment.complete() function.

```
try {
    const accept = await Accept(captureContext);
    const up = await accept.unifiedPayments(sidebar);
    const tt = await up.show(showArgs);
    const completeResponse = await up.complete(tt);

    console.log(completeResponse); // merchant logic for handling complete response
} catch (error) {
    // merchant logic for handling issues
    console.error("something went wrong: " + error);
}
}
```

When you include this in your capture context, `Unified Checkout` is leveraged to initiate payment and any follow-on services that you include in your capture context request. Alternatively, you can call the payment APIs directly. See [Authorizations with a Transient Token](/docs/cybs/en-us/digital-accept-flex/developer/all/rest/digital-accept-flex/uc-intro/uc-auth-tokens.md "").
