Email Processing

We support processing over email. You can send a PDF to our designated email address via attachments and we will process it as if you uploaded it via the API.

Your users email must match the sender

For us to securely process your documents, we need to verify that the email is sent from your users. So please make sure that your Areal user’s email matches the sender of the email.

Attachments is all you need

We only care about the attachments in the email. Body will be ignored. Your email body will be ignored.

Example Usage
