MerchantValidationEvent: complete() method
Secure context
The MerchantValidationEvent method complete() takes merchant-specific information previously received from the validationURL and uses it to validate the merchant.
All you have to do is call complete() from your handler for the merchantvalidation event, passing in the data fetched from the validationURL.
Syntax
complete(validationData)
complete(merchantSessionPromise)
Parameters
validationDataormerchantSessionPromise- : An object containing the data needed to complete the merchant validation process, or a
Promisewhich resolves to the validation data.
- : An object containing the data needed to complete the merchant validation process, or a
Return value
None (undefined).
Exceptions
This exception may be passed into the rejection handler for the promise:
InvalidStateErrorDOMException- : Returned if the event did not come directly from the user agent, but was instead dispatched by other code. Another payment request is currently being processed, the current payment request is not currently being displayed to the user, or payment information is currently being updated.
Examples
In this example, we see the client-side code needed to support merchant validation for a payment request called payRequest:
payRequest.onmerchantvalidation = (event) => {
const validationDataPromise = getValidationData(event.validationURL);
event.complete(validationDataPromise);
};
function getValidationData(url) {
// Retrieve the validation data from the URL
// …
}
This code sets up a handler for the merchantvalidation event. The event handler calls a function, getValidationData(), which retrieves the data from the validation URL, then passes that data (or a promise to deliver the data) into complete().
