Each SDK covers listing, creating, uploading, retrieving and correcting documents, plus workflow event dispatch.
Process your first document
curl -X POST "https://api.formalini.com/api/public/v1/documents/upload" \ -H "Authorization: Bearer $FORMALINI_API_KEY" \ -F "file=@invoice-page-1.jpg" \ -F "name=Invoice example"
The upload endpoint accepts JPEG, PNG, WebP and HEIC page images. Keep API keys on your server — never in browser code.
