Hi, I have a document in base64 like ‘data:application/pdf;base64,{base64string}’ and I need it to use it in File parameter for creating a document in signaturit. I end up having a 400 bad request and signaturit says ‘wrong document list’ cause its application/octet-stream. Is any way around for this kind of stuff? Any help? Thank you

The File field expects file objects or a file link, which is a public direct download url.
