POST /businesses/{bid}/documents/{id}/prints

Requires the documents scope.

Israeli law delivers the origin (מקור) exactly once, per הוראה 18(ב)2. auto is what a download button should send: it serves the origin on the first ever print and a copy forever after, so a repeat click never errors, and the X-Print-Variant header tells you which one you got.

A pdf_pending response never consumes the origin.

Path parameters

NameTypeDescription

Body (optional)

FieldTypeDescription

Response

Response header X-Print-Variant: Which variant these bytes are.

Errors: 400, 401, 403, 404, 409, 429. Every failure answers { "error": …, "reason": … }. Branch on reason.
