  -F "files=@/path/to/receipt.pdf"

const formData = new FormData();
formData.append('files', fileInput.files[0]);

const response = await fetch('https://api.pazy.io/v1.0/invoice/<invoiceId>/supporting-documents', {
  method: 'POST',
  headers: {
    'Authorization': 'Api-Key YOUR_API_KEY'
  },
  body: formData

Best Practices

Repeat the files field name to upload multiple documents in a single call — they are saved as separate supporting documents
Use the Invoice Supporting Documents API to list the documents already attached to an invoice
Each file is capped at 50 MB; split larger files before uploading
Supporting documents are stored separately from the original invoice file uploaded via the Invoice Creation API
