Hello, I have an application that takes an image, and converts the image to a pattern for knitting. I'm using flask to create a website that allows users to upload the image and generates them a GUID. I'm intending to integrate paypal's Buy Now button mechanism, but I'm having trouble figuring out how to feed my GUID through the html form generated by paypal. I've tried using the "Advanced variables" which says the option will be included in the HTML, but the button code that gets generated doesn't have anything different. The documentation for this under the "Learn more" link also leads to a dead end. Can someone point me to a possible solution for my use case? It would be ideal if I could just feed the GUID as a transaction label or metadata to paypal. I just need a little push in the right direction or an example to get going. Thanks, Brandon
