PaymentRequest: canMakePayment() method
Limited availability
This feature is not Baseline because it does not work in some of the most widely-used browsers.
Secure context: This feature is available only in secure contexts (HTTPS), in some or all supporting browsers.
The PaymentRequest method
canMakePayment() determines whether or not the request
is configured in a way that is compatible with at least one payment method supported
by the user agent.
You can call this before calling
show() to provide a streamlined user experience
when the user's browser can't handle any of the payment methods you accept.
For instance, you might call canMakePayment() to determine if the browser
will let the user pay using Payment Request API, and if it won't, you could fall back to
another payment method, or offer a list of methods that aren't handled by Payment
Request API (or even provide instructions for paying by mail or by phone).
Syntax
canMakePayment()
Parameters
None.
Return value
A Promise to a boolean value that resolves to true
if the user agent supports any of the payment methods supplied when instantiating the
request using the PaymentRequest
constructor. If the payment can't be processed, the promise receives a value of
false.
Note:
If you call this too often, the browser may reject the
returned promise with a DOMException.
Examples
In the following example, is excerpted from a demo that asynchronously builds a PaymentRequest object for
both Apple Pay and Example Pay. It wraps the call to canMakePayment() in
feature detection, and calls an appropriate callback depending on the resolution of the
Promise.
async function initPaymentRequest() {
const details = {
total: {
label: "Total",
amount: {
currency: "USD",
value: "0.00",
},
},
};
const supportsApplePay = new PaymentRequest(
[{ supportedMethods: "https://apple.com/apple-pay" }],
details,
).canMakePayment();
// Supports Apple Pay?
if (await supportsApplePay) {
// show Apple Pay logo, for instance
return;
}
// Otherwise, let's see if we can use Example Pay
const supportsExamplePay = await new PaymentRequest(
[{ supportedMethods: "https://example.com/pay" }],
details,
).canMakePayment();
if (supportsExamplePay) {
// show Example Pay support
return;
}
// Otherwise, make payments using HTML form element
}
