Download the Hacienda message for purchase invoices
GET /api/v1/facturas-compra/{clave}/respuesta
Returns the Hacienda response XML for the purchase invoice: the acknowledgment signed by the Ministry stating whether the document was accepted or rejected, and for what reason. Same behavior as GET /facturas/{clave}/respuesta, applied to the 08-type key space.
It is a different document from the one obtained in Download purchase invoice XML — that one corresponds to the document itself, signed by whoever issued it — and this is the one that serves as proof in an audit that Hacienda received it and what it resolved.

{ "mensaje": "El comprobante existe pero Hacienda todavía no ha respondido." }Hacienda’s acknowledgment arrives asynchronously, minutes after issuance. This status means “no response yet; retry later,” not “doesn’t exist” — that’s why it isn’t a 404.
404 Not Found
{ "error": "Comprobante no encontrado." }The key doesn’t correspond to any purchase invoice for the tenant, or it corresponds to a document that isn’t of type 08.
Operational notes

rechazada(rejected) purchase invoice does have a response: the XML is exactly where Hacienda explains the reason for the rejection.202doesn’t mean rejection, it means Hacienda hasn’t answered yet. - The acknowledgment arrives automatically, with no need to request it.
