  description: |
    Flutterwave delivers webhook events for payments, transfers, refunds,
    chargebacks, and virtual account funding. This document describes the
    outbound HTTP callbacks Flutterwave will send to a merchant-configured
    endpoint. The receiver must respond with 2XX within 5 seconds; Flutterwave
    retries with exponential backoff.
