The available fields
Fortnox invoices carry several reference fields that Junipeer can search:
Shop order ID (e.g. Shopify order number) - Typically it's connected to Shop order ID (e.g. Shopify order number)
Secondary reference (PSP token, checkout ID) - Typically it's a Secondary reference (PSP token, checkout ID)
DocumentNumber - This usually maps to Fortnox's own internal number
OurReference - Internal reference, rarely used for matching
YourOrderNumber - Only available on invoices, not usable for filtering orders
