The receipts endpoint generates a legal receipt for an order across any product (letter, telegram, e-mail or WhatsApp).

Endpoint

Full request/response details live in the API Reference tab.

Usage

  • order_id — the order’s visual id (required): numeric for letters and telegrams (e.g. 2607031), E-prefixed for registered e-mails (e.g. E2607031), or the WhatsApp visual id.
  • typeletter, telegram, email or whatsapp. Auto-detected when omitted.
  • format=html — preview the receipt as HTML instead of downloading a PDF (letter, telegram and e-mail receipts only; WhatsApp always returns the expert-report PDF).
A successful response is the binary PDF (or HTML). Error responses use the standard JSON envelope {"status", "status_message", "data"} — a 403 means the order does not belong to your account.
