Adyen Payment Gate Failure


If you are integrating the checkout with the Adyen payment gateway and the payment gateway keeps failing, it is most likely due to CORS, Adyen's security policy.

Payment Failed

You can verify the issue by using the Developer Console and finding this error:

To access the Developer Consoler, right-click on the page and select 'Inspect' or 'Inspect Element'. Then switch to the Console tab.


Login to your Adyen account.

Client key should be the same as in the Ventrata dashboard under Supplier Settings > Gateways > [select gateway] and scroll to the bottom of the form.

Go to Developers > API credentials.
Select your company account.
Under Allowed origins, enter the domain where the checkout will be implemented.

In the ws entry, add the domain URLs you will be using.

Press the Add button.
Press the Save changes button.

If you are using Adyen VentrataPayments and encounter this issue, please contact your account manager.
