Direction: Inbound (QI Tech / payment infrastructure → BNPL WL). Partners do not call this endpoint directly.

Webhook endpoint for receiving refund status change notifications. This is triggered when a refund transitions between states. Use this to track refund progress asynchronously, especially useful when a refund request times out.

Common status transitions:

• PENDING -> LIMIT_RESTORED: Customer credit limit has been restored; the refund transfer (PIX) is still being processed
• LIMIT_RESTORED -> COMPLETED: Refund transfer processed successfully
• PENDING -> FAILED: Refund processing failed
• PENDING -> ACTION_REQUIRED: Refund needs partner action (e.g., invalid PIX key — collect a new one from the customer)
• ACTION_REQUIRED -> LIMIT_RESTORED: Partner resubmitted corrected PIX data; credit limit already restored, transfer now in progress
