We´re running into a case that needs to sign the invoices using a digital certificate and we´re wondering if this would be possible in Bubble and if anyone can point us into a direction from where to start.
The thing is that whenever a user saves an invoice, it needs to be signed with the user´s digital certificate. Because in Spain is something that is going to be mandatory using certificates such as the FNMT one like Xataka guys explain in their post of digital certificates.
From what I can understand of the underlying tech (it mentions Mozzila and Internet Explorer so that is a bit of a worry) it is something that runs on a desktop.
So maybe you need to save the invoice to their machine, get them to sign it, and then reupload?
As far as I´ve seen, with this certificate sign things, what happens is: you click on a button that says “sign” and then a popup shows with the certificates installed in your browser, you choose the certificate and then sign the document.
First is getting the key onto your computer. It is installed in your OS as it needs to use the configuration of your browser/OS to prove that it is your computer.
I cannot think that Bubble would be able to access this certificate and the information required to sign the document.
You would have to save the document, get them to sign it locally, and upload.
A possible alternative is a cloud based signature storage.
There are APIs for Global Sign…
But it looks like this is just ordering and managing, rather than signing. So it would allow an enterprise to manage certificates used in Acrobat for example.
Maybe email them and ask? Other than that, download to device, sign, upload.

since it´s a bit complicated.
