Use Auth Token Get Method

Is this possible, anyone could help me? I need to access a PDF from URL with auth

The OCR API can not do authentication. I see two options:

1A Use a hidden link instead of Auth token

1B For PRO PDF users, we can provide you with a fixed IP address. You can allow access from only this IP.

Or: 2. Download the PDF on your side, and upload it to the OCR API
