The securePaymentConfirmationAvailability() static method of the {{domxref("PaymentRequest")}} interface indicates whether the Secure payment confirmation (SPC) feature is available.

Syntax

js-nolint
securePaymentConfirmationAvailability()

Parameters

None.

Return value

A {{jsxref("Promise")}} that resolves with an enumerated value indicating whether SPC is available, and if not, a reason for non-availability.

Possible values are:

  • available
    • : SPC is available in the calling frame. This doesn't guarantee that an SPC-compatible credential is available to authenticate against.
  • unavailable-unknown-reason
    • : SPC is not available in the calling frame, for an unknown reason. The browser may return this result instead of a more specific reason, in order to protect user privacy.
  • unavailable-feature-not-enabled
    • : SPC is not available in the calling frame because it is not enabled.
  • unavailable-no-permission-policy
  • unavailable-no-user-verifying-platform-authenticator
    • : SPC is not available in the calling frame, because there is no user-verifying platform authenticator available ({{domxref("PublicKeyCredential.isUserVerifyingPlatformAuthenticatorAvailable()")}} can also be used to discern this information).

Examples

js
async function spcSupport() {
  const support = await PaymentRequest.securePaymentConfirmationAvailability();
  if (support === "available") {
    // Commence SPC payment flow
  } else {
    // Fallback to traditional flows
  }
}
