Sending files

When you supply a PDF, we can extract the links, abstract, and other metadata.

Supply the file_url parameter in your Submission, and we will retrieve the file from your server.

We recommend that you protect your content by requiring authorization headers to retrieve these files. See Auth Headers.

Alternatively, you can send a short-lived pre-signed URL, for example an AWS S3 URL. If you do this, please use a short timeout (such as 1 hour) for security.

We do not support POSTing files directly to the API.

Prerequisites

  1. Contact us to authorize a domain for retrieving files. This can be the same domain as your callbacks.
  2. Send us a shared secret so that we can authorize request headers.
