Regarding quick view f.i. ==> (belts for sale) [login to view URL] (go over this product and click then on view). See for App Store in SEO shop: [login to view URL] with following credentials an app can be installed to get an impression how everything works: [will pass once we have contact] Over here a REST/JSON connecection (API) has to be done between SEOshop and probably the server of webbing.nl. What then will happen is that when a webshop owner will click "buy app" then a connection will be made between WebshopX and the server of [login to view URL], so the app will be then installed (I do assume that will happen). The quick view (query) we can provide. De API integration and ad tasks has to be done to let work everything smoothly. Add info: –> [login to view URL] For dev/test environment, see below.
