I have a client who sells software licenses through another website, whose shopping cart they have connected to PayPal, and they wanted an easy way for their customers to purchase these licenses through their Wix site, so I thought that an iframe would be the path of least resistance.
Unfortunately, there is a hiccup in the process that is preventing successful checkout, and I believe it has to do with Wix rerouting the iframe's URL through htmlcomponentservice.com, which I have been told I may need to whitelisted by PayPal ...
Anyone have any insight?
