Overview

Confirms a pending extra-charge batch created by /extra-charges/precharges. Captures the Stripe PaymentIntent, bills the credit line, charges the card stored on the booking's account (ACC_CREDIT_CARD; in sandbox mode, recorded without charging the card), or (MANUAL) records the lines as awaiting_payment, then appends the lines to the booking.

Access

Requires Flights API access. Post-booking extra charges are not enabled by default — contact the LiteAPI support team to request access.

Idempotency

Idempotent on chargesId, mirroring POST /flights/bookings prebookId replay:

• Already confirmed — HTTP 200 with data.message and the persisted extras (no re-capture / no duplicate credit-line billing)
• Concurrent confirm — HTTP 409 / 45035 while another confirm for the same chargesId holds the Redis lock; retry after the first completes

When to Use

• After the customer confirmed the Stripe PaymentIntent (status requires_capture / succeeded), or immediately for CREDIT and ACC_CREDIT_CARD

Constraints

• Body only needs chargesId + payment (charge lines are encoded in chargesId)
• payment.method must match the method chosen at precharges (TRANSACTION_ID, CREDIT, ACC_CREDIT_CARD or MANUAL); ids minted before methods were recorded must use the booking's original payment
• For Stripe, payment.transactionId must be the id returned by precharges
