DeprecatedThis feature is no longer recommended. Though some browsers might still support it, it may have already been removed from the relevant web standards, may be in the process of being dropped, or may only be kept for compatibility purposes. Avoid using it, and update existing code if possible; see the compatibility table at the bottom of this page to guide your decision. Be aware that this feature may cease to work at any time.

Non-standard This feature is non-standard and is not on a standards track. Do not use it on production sites facing the Web: it will not work for every user. There may also be large incompatibilities between implementations and the behavior may change in the future.

Secure contextThis feature is available only in secure contexts (HTTPS), in some or all supporting browsers.

The MerchantValidationEvent() constructor creates a new MerchantValidationEvent object. You should not have to create these events yourself; instead, just handle the merchantvalidation event.

merchantValidationEvent = new MerchantValidationEvent(type, options);

Parameters

type: A DOMString which must be merchantvalidation, the only type of event which uses the MerchantValidationEvent interface.
options Optional: An optional dictionary which may contain zero or more of the following properties:

methodName Optional A DOMString containing the payment method identifier for the payment handler being used. This is an empty string by default. validationURL Optional The URL from which to retrieve payment handler specific verification information used to validate the merchant. This is an empty string by default.

Return value

A newly-created MerchantValidationEvent providing the information that needs to be delivered to the client-side code to present to the user agent by calling complete().

Exceptions

TypeError: The string specified as validationURL could not be parsed as a URL.
RangeError: The specified methodName does not correspond to a known and supported merchant or is not a well-formed standard payment method identifier.
