[Spryng] An AJAX call to https://{sandbox/api}.spryngpayments.com/card does not work in Chrome: «No 'Access-Control-Allow-Origin' header is present on the requested resource»

XMLHttpRequest cannot load https://sandbox.spryngpayments.com/card.
Response to preflight request doesn’t pass access control check: No ‘Access-Control-Allow-Origin’ header is present on the requested resource.
Origin ‘https://localhost.com:900’ is therefore not allowed access.

A response from Spryng:

Excuse me, it’s https://sandbox.spryngpayments.com/v1/card, with ‘v1’
