[Authenticity information](https://argyle.com/docs/integrations/ocr/document-ocr-processors#authenticity-information) for uploaded documents is now available via the API when Ocrolus document processing is enabled.

The following properties have been added to the [users forms endpoint](https://argyle.com/docs/api-reference/user-forms#upload-ocr_authenticity_score):

* `ocr_authenticity_score` — Single integer score that captures the likelihood an uploaded document is authentic, as determined by Ocrolus.
* `ocr_authenticity` — Object containing details on individual instances of tampering or other authenticity-related edits.

The following [webhook](https://argyle.com/docs/api-reference/user-forms-webhooks#ocr-authenticity) is now available:

* `user_forms.ocr_authenticity` — Sent when authenticity information is available for an uploaded document.

*Ocrolus OCR and authenticity for uploaded documents can be purchased through Argyle directly. For purchasing and setup assistance, please reach out to our customer success team.*
