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
merchantValidationEvent.complete(validationData); merchantValidationEvent.complete(merchantSessionPromise);
Parameters
validationData
ormerchantSessionPromise
- An object containing the data needed to complete the merchant validation process, or a
Promise
which resolves to the validation data.
Return value
undefined
.
Exceptions
This exception may be passed into the rejection handler for the promise:
InvalidStateError
- 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.
Example
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()
.
