# FAQs ## What's the difference between a voucher and a ticket? Under each product in the [mapping](/octo-core/products.md) section, we provide a `deliveryMethods` key. This is an array containing one or both of the following values: * `VOUCHER`: A single barcode/ticket for the whole booking, regardless of how many tickets were bought. * `TICKET`: An individual barcode/ticket per person (unit). Once a booking is confirmed: * `booking.voucher` is provided if `deliveryMethods` contains `VOUCHER`. * `booking.units[].ticket` is provided if `deliveryMethods` contains `TICKET`. * If a method is not available, its value is `null`. If both are provided, you can use either format based on your user experience and guest preference. All Ventrata-operated products support both delivery methods, but some attractions require a separate barcode per person. In these situations, you will have only `TICKET` and not `VOUCHER`. Make sure to check `deliveryMethods` for each product. ## Do vouchers/tickets always come with both PDF and QR code? If so, which should I use? Yes. Ventrata always offers both PDF and QR code delivery formats for vouchers and tickets. If possible, support both: show the QR code in your interface and provide the PDF as a download option. The PDF includes full redemption details. ## What is the difference between `booking.supplierReference` and barcode? For each booking (and unit/ticket), we provide a QR code value and a supplier reference. In some cases, the barcode is very long and contains enough data to allow it to be verified offline. You should **NOT** print the QR code value in plain text. Instead, print the supplier reference below the QR code, which is always compact and human-readable. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
