How to configure your own S3 bucket for PDF form submissions

October 11, 2024

Benjamin André-Micolon

When your customers edit and fill a document using SimplePDF in your portal or the embed editor connected to your portal, the document as well as the submissions are securily saved on SimplePDF storage (S3 bucket).

However for various reasons, such as compliance to specific rules in your country or industry, you may wish this document to be saved in your own storage.

How the upload works

Feel free to jump to the next section to see how to configure your S3 bucket

Let's quickly review the flow of the S3 upload:

As security and privacy is paramount to us, we want to emphasize a couple of things about the upload flow:

• The SimplePDF server never sees the document: all interactions (upload and download) happen in the browser.
• The upload and download of documents (when reviewing customer submissions in your account) are performed using short-lived pre-signed URLs using the s3 credentials (SimplePDF's own or your own)
