Sending images and scanned PDFs for translation

To translate scanned PDF or image file and get result as PDF, send a POST request to the https://api.groupdocs.cloud/v2.0/translation/image-to-file GroupDocs.Translation Cloud REST API endpoint. To authorize the request, pass the access token in Authorization header (Bearer authentication).

The file and translation parameters are provided in JSON format in the request body.

  ],
  "file": "string",
  "url": "string",

}
