Understand how to retrieve e-invoice results using billing document IDs, including specific fields for the India e-invoicing process.

You can use the "Retrieve e-invoicing results" operation to retrieve e-invoice results according to the ID of a billing document. The document ID can be the ID of an invoice, a credit memo, or a debit memo.

The e-invoicing result fields might be different by country. For example, a QR code and an IRN are returned for the India e-invoicing clearance process.

The e-invoicing result fields on EInvoiceData include the following fields for India:

• QrCode : This field stores the QR code data that has been Base64 decoded. In India, the code is a signed QR code in the format of JSON Web Token (JWT), consisting of three parts: signature parameters, data, and a signature.

• ReferenceNumber : This field stores a unique number generated by the tax authority. In India, it is known as the Invoice Reference Number (IRN). IRN is a distinct code created by the Invoice Reference Portal (IRP) for every electronic invoice (e-invoice) file issued under the Goods and Services Tax (GST) system. This number is essential for verifying and authenticating e-invoice files within the Indian e-invoicing system.

• DocumentId : This field stores the ID of the billing document, for which the e-invoice file is generated.

• DocumentType : This field indicates the type of the billing document, for which the e-invoice file is generated.

The eInvoiceFileId field on the Invoice object stores the ID of the Base64-encoded e-invoice file, a cleared document in JSON format.
