Email [[email protected]](https://bannx.com/cdn-cgi/l/email-protection#7a1915140e1b190e3a181b14140254191517). Is there an editor we can white-label inside our app? No. The embed puts one design's form, live preview and download in an iframe on your page, and each download is billed to your space. For anything else, call the API from your backend. Can each customer's file carry their own brand? Is there an API key in the image URLs? Can I limit what a key can do? What does it cost? ## Your product's images and PDFs, from one template.
