Upload pdf and generate qr code for the file

[frankwanglinked]

Hi, there. I got below request thinking of how to come up with a solution, anyone have any ideas?

Want to save a form with a pdf file uploaded, then:

1- auto generate a id# for the pdf file.

2- and use some API to generate qr code by using this id#

3- then put the qr code into the pdf file which means will edit the pdf file.

4- can serach or download the new pdf
