Hello,
we have built website which enables customers to create their own products and upload them to our server to manufacture.
Right now we are choosing proper e commerce solution, and while ecwid looks nice enough, we re not sure about the custom possibilities with it.
Would it possible lets say, that upon uploading of the file unique string is generated, which refer to the file and gets somehow "fed" to the checkout, so we know which order references which upload?
Hope the question is somehow clear, any help greatly appreciated.
thx,
miro
