GET
Download a printable invoice
This endpoint requires authentication (API key or dashboard session) and is tenant-scoped — the rendered document carries the buyer’s legal name, address, and GSTIN, so invoices are never publicly fetchable by UUID.
Returns a print-ready HTML rendering of the invoice. The layout is jurisdiction-aware: India-GST sellers get a full TAX INVOICE (GSTIN, per-line HSN, CGST/SGST or IGST split, Place of Supply, e-invoice IRN/QR when present); other sellers get a plain invoice with a single tax line and the seller’s tax id. Amounts render with the invoice currency’s own symbol.

Path Parameters

Response

200 with Content-Type: text/html — a self-contained, print-ready document (use the browser’s print-to-PDF for a PDF file). 401 without valid credentials; 404 when the invoice doesn’t exist in your tenant.
GET /v1/invoices/{id}/preview returns the identical rendering and exists for dashboard preview use.
