After creating a callback request as explained here:
I notice that for mutations Bunq calls my endpoint and sends json as the raw body of its request.
The json array has one top level key "NotificationUrl" inside which there is an "object" array with one key "Payment".
Is this "Payment" key always available for all types of payments:
(paying a Request, iDEAL, Sofort or Invoice) or are there other keys for these payment types?
