Private pages

Many real PDF workflows involve private content: invoices, dashboards, internal documentation, and user-specific views. The general patterns for headers, secrets, endpoint selection, and proxy are covered in private pages patterns.

This page shows the PDF-specific setup.

Use x-api-header-* to forward secrets without exposing them in the URL:

curl -G https://pro.microlink.io \
  -d url=https://example.com/dashboard \
  -d pdf=true \
  -d meta=false \
  -H 'x-api-key: YOUR_API_TOKEN' \
  -H 'x-api-header-cookie: session=abc123'

If the page is authenticated and protected by antibot systems, CAPTCHAs, or geofencing, you may also need proxy . If you see EPROXYNEEDED, that confirms it.
