    Forward Compatibility

    The API is designed for longevity. To ensure your integration is resilient to additive changes:
    Ignore unknown fields in response objects. New fields may be added without notice.
    Handle unknown enum values gracefully. New values may be added to open enums (e.g. new payout statuses, new webhook event types).
    Do not depend on field ordering in JSON responses
    These additive changes are not considered breaking and will not trigger a new API version.
