In the Payments API, not all Payments are linked to a reservation number.
This makes it impossible to match off payments against invoices in an external accounting system. This is despite in some cases when looking at a payment in Mews it can be seen to be related to a reservation although sometimes the Reservation field is blank.
In some cases this is explained by someone paying for two or more rooms at the same time. But, this also needs a solution, as it would make sense for the single payment to be matched off against the multiple reservations.
Is it possible to for the Reservation number to be mandated in the API for payment related to Reservations?
