Change the processing type of a Document from Classify to Instant, or from Instant to Complete—without changing the Book’s book_class.

Use this endpoint when only some documents need a higher processing tier and you want new uploads to continue following the Book’s current class.

For Book-level class changes, use the Book Upgrades and Update Book endpoints. For mixed PDFs, use the Upgrade a mixed document endpoint.

Requirements

• Document-level upgrades must be enabled for your organization. If not, contact your Ocrolus account manager.
• The document must finish its current processing before you upgrade it.
• Child documents that belong to a mixed document cannot be upgraded with this endpoint. Upgrade the mixed document instead.
• If the Book is already Complete, or a Book upgrade already covers the same target, the document upgrade is rejected.
• On success, the document re-enters processing under the new tier. Re-fetch Capture or Analyze data after verification completes.

When to use this endpoint

Upgrade types

Document upgrades are forward-only. You cannot downgrade a document from Complete back to Instant.
