Resubmit Refund Ticket - Waffo Pancake

POST /api/actions/refund-ticket/resubmit-ticket Authentication: Merchant API Key (server-to-server). Resubmit reuses the request shape of Create Refund Ticket, plus a ticketId to identify the ticket being revised. The originating paymentId is bound to the existing ticket and cannot be changed.

Request body

Field	Type	Required	Description
`ticketId`	string	Yes	Short ID of the refund ticket being revised, e.g. `TKT_3bVzrkD0FJjFdZNLk8Ualx`
`reason`	string	Yes	Free-text reason for the revised request
`requestedAmount.amount`	string	Yes	Revised refund amount (display format, must be `> 0` and `≤ payment.amount`)
`requestedAmount.currency`	string	Yes	ISO 4217 code, must match the payment currency

The refundTicketMerchantExternalId written at create time is immutable across resubmits — it cannot be changed once the ticket exists.

Success response (200)

A new ticket version is appended; versionNumber increments. The ticket re-enters the review queue (pending for customer-initiated, processing for merchant-initiated).
