This example will validate the conformance of an uploaded PDF file. It returns a report with the level of conformance of the PDF/A file and the errors encountered during validation.

Try it out in three steps

  1. Add a PDF named pdfa.pdf to your project folder.
  2. Run the code from the same folder.
  3. Open result.json to see the output.
curl -X POST https://api.nutrient.io/validate_pdfa \
  -H "Authorization: Bearer your_api_key_here" \
  -o result.json \
  --fail \
  -F file=@pdfa.pdf
