Body
Response
Check refund eligibility and estimated amount
true
True when committing would VOID the ticket outright — the document is still inside its void window, so the original charge is reversed in full instead of a fare-rule refund being computed. On a void, refund_amount is legitimately absent: the caller gets total_paid back. Time-sensitive — read it from a live check, never from stored booking data.
false
true
How this action can be carried out. AUTO — the platform completes it end to end through the API. MANUAL_REQUIRED — it is possible, but a Jinko agent has to act; call the API to raise it and expect a delay rather than an immediate result (manual_reason says why). UNSUPPORTED — the provider or fare does not allow it at all; nothing you send will change that. Do not treat MANUAL_REQUIRED as a failure, and do not retry UNSUPPORTED.
AUTO, MANUAL_REQUIRED, UNSUPPORTED Why a person has to act. Present with support_level: MANUAL_REQUIRED.
"fare rules require agent review"
What would be refunded. Absent is not zero — on a voidable ticket (is_voidable: true) the whole charge is reversed and no amount is quoted, and on an unsupported refund nothing is computed at all. Read is_refundable and is_voidable before showing a figure.
