Reverse a Returned Payment
Exactly 2 API calls. The payment voucher already exists — find it and reverse it.
Call 1: Find Payment Voucher
On a fresh sandbox there are very few vouchers. The payment voucher's description always starts with "Betaling:". Find it directly — no need to search for customer or invoice first.
GET /ledger/voucher?dateFrom=2020-01-01&dateTo=2030-12-31&fields=id,description,date&count=50
Find the voucher whose description starts with "Betaling:". That's the payment to reverse.
Call 2: Reverse It
PUT /ledger/voucher/<voucher_id>/:reverse?date=2026-03-20
Total: 2 calls, 0 errors.
Gotchas
