Export Quote PDF
Creates a download link for a PDF with information on a specific quote based on the provided `quoteId`.
The PDF does not use one of the buyer-facing templates that can be selected for PDFs and emails. Instead, it uses a non-configurable template that also communicates backend information, like storefront channel and line item cost margins.
You can optionally update the currency information and also supply a custom exchange rate by using the `currency` array.
