Get Generated PDF Document

Retrieves the status and result of a document generation request. The response includes the request status (success or failed), the generated document’s ID and name, the queue and user involved, and error details if generation or scanning failed. Poll this endpoint after creating a document to confirm it has been generated. ## Singapore e-invoice status This is also the **status-polling endpoint for Singapore e-invoices**. Poll it with the `requestId` returned by `POST /v2/einvoice/ar/{qid}`. For e-invoice requests the response additionally carries: - **`peppolSendStatus`** — Peppol delivery state: `PENDING`, `SENT_SUCCESSFULLY`, `FAILED_TO_SEND`, `INVALID_XML_FORMAT`, `CONSUMER_NOT_FOUND` (or `null` for IRAS-only flows that never send over Peppol). - **`irasTaxSubmissionStatus`** — IRAS tax reporting state: `NOT_SUBMITTED`, `SUBMITTED` / `SUCCESSFUL_IRAS_SUBMISSION`, `FAILED_TO_SUBMIT` / `REJECTED_IRAS_SUBMISSION`, `INVALID_XML_FORMAT`, `NETWORK_TRANSMISSION_ERROR` (or `null` when the flow does not report tax). Both channels are asynchronous — keep polling until they reach a terminal state.
