I set up Facturae_3.2.2 (I am from Spain), but I have encountered several problems:
The digital certificate (.p12 format) that I upload does not appear in the configuration window, I only have a message (that disappears after a few seconds) that the certificate has been uploaded but in the configuration still appears the box to upload or drag the file. I put the private key of the certificate and save changes in case it is a GUI problem.
I generate the XML file and send it to the web to verify that it is correct and it gives errors in the DNI field (identifier, CIF, NIF) and cannot validate the signature.
I edit the XML with a text editor and in the identifier field appears the DNI+invoice number, so obviously it is wrong. Nowhere appears anything related to the digital signature, so the certificate is not being included (do I have to activate something to include the signature in the invoice?).
In my case it is not a company and it is a person (self-employed) and I had to change in the company details the field Class, choosing the option “Individual”.
Making this change the invoice is already accepted in FACe.
Including the signature.
I need to correct one more thing, in the XML there is no information of the taxes, in Spain they are VAT and IRPF.
