Once you’ve got Paperless setup, you need to start feeding documents into it. Currently, there are three options: the consumption directory, IMAP (email), and HTTP POST.

The Consumption Directory

The primary method of getting documents into your database is by putting them in the consumption directory. The document_consumer script runs in an infinite loop looking for new additions to this directory and when it finds them, it goes about the process of parsing them with the OCR, indexing what it finds, and encrypting the PDF, storing it in the media directory.

Getting stuff into this directory is up to you. If you’re running Paperless on your local computer, you might just want to drag and drop files there, but if you’re running this on a server and want your scanner to automatically push files to this directory, you’ll need to setup some sort of service to accept the files from the scanner. Typically, you’re looking at an FTP server like Proftpd or Samba.

So where is this consumption directory? It’s wherever you define it. Look for the CONSUMPTION_DIR value in Set that to somewhere appropriate for your use and put some documents in there. When you’re ready, follow the consumer instructions to get it running.

Hooking into the Consumption Process

Sometimes you may want to do something arbitrary whenever a document is consumed. Rather than try to predict what you may want to do, Paperless lets you execute scripts of your own choosing just before or after a document is consumed using a couple simple hooks.

Just write a script, put it somewhere that Paperless can read & execute, and then put the path to that script in paperless.conf with the variable name of either PAPERLESS_PRE_CONSUME_SCRIPT or PAPERLESS_POST_CONSUME_SCRIPT. The script will be executed before or or after the document is consumed respectively.


These scripts are executed in a blocking process, which means that if a script takes a long time to run, it can significantly slow down your document consumption flow. If you want things to run asynchronously, you’ll have to fork the process in your script and exit.

What Can These Scripts Do?

It’s your script, so you’re only limited by your imagination and the laws of physics. However, the following values are passed to the scripts in order:

Pre-consumption script
  • Document file name
Post-consumption script
  • Document id
  • Generated file name
  • Source path
  • Thumbnail path
  • Download URL
  • Thumbnail URL
  • Correspondent
  • Tags

The script can be in any language you like, but for a simple shell script example, you can take a look at in the scripts directory in this project.

IMAP (Email)

Another handy way to get documents into your database is to email them to yourself. The typical use-case would be to be out for lunch and want to send a copy of the receipt back to your system at home. Paperless can be taught to pull emails down from an arbitrary account and dump them into the consumption directory where the process above will follow the usual pattern on consuming the document.

Some things you need to know about this feature:

  • It’s disabled by default. By setting the values below it will be enabled.
  • It’s been tested in a limited environment, so it may not work for you (please submit a pull request if you can!)
  • It’s designed to delete mail from the server once consumed. So don’t go pointing this to your personal email account and wonder where all your stuff went.
  • Currently, only one photo (attachment) per email will work.

So, with all that in mind, here’s what you do to get it running:

  1. Setup a new email account somewhere, or if you’re feeling daring, create a folder in an existing email box and note the path to that folder.
  2. In set all of the appropriate values in MAIL_CONSUMPTION. If you decided to use a subfolder of an existing account, then make sure you set INBOX accordingly here. You also have to set the UPLOAD_SHARED_SECRET to something you can remember ‘cause you’ll have to include that in every email you send.
  3. Restart the consumer. The consumer will check the configured email account every 10 minutes for something new and pull down whatever it finds.
  4. Send yourself an email! Note that the subject is treated as the file name, so if you set the subject to Correspondent - Title - tag,tag,tag, you’ll get what you expect. Also, you must include the aforementioned secret string in every email so the fetcher knows that it’s safe to import.
  5. After a few minutes, the consumer will poll your mailbox, pull down the message, and place the attachment in the consumption directory with the appropriate name. A few minutes later, the consumer will import it like any other file.


You can also submit a document via HTTP POST. It doesn’t do tags yet, and the URL schema isn’t concrete, but it’s a start.

To push your document to Paperless, send an HTTP POST to the server with the following name/value pairs:

  • correspondent: The name of the document’s correspondent. Note that there are restrictions on what characters you can use here. Specifically, alphanumeric characters, -, ,, ., and are ok, everything else it out. You also can’t use the sequence ` - ` (space, dash, space).
  • title: The title of the document. The rules for characters is the same here as the correspondent.
  • signature: For security reasons, we have the correspondent send a signature using a “shared secret” method to make sure that random strangers don’t start uploading stuff to your server. The means of generating this signature is defined below.

Specify enctype="multipart/form-data", and then POST your file with:

Content-Disposition: form-data; name="document"; filename="whatever.pdf"

Generating the Signature

Generating a signature based a shared secret is pretty simple: define a secret, and store it on the server and the client. Then use that secret, along with the text you want to verify to generate a string that you can use for verification.

In the case of Paperless, you configure the server with the secret by setting UPLOAD_SHARED_SECRET. Then on your client, you generate your signature by concatenating the correspondent, title, and the secret, and then using sha256 to generate a hexdigest.

If you’re using Python, this is what that looks like:

from hashlib import sha256
signature = sha256(correspondent + title + secret).hexdigest()
