FuzeMetrix
Many of the world’s busiest non-USA wind tunnels run their bookings on FuzeMetrix (FM), a third-party booking platform. The IBA integrates with FuzeMetrix so that members at FM tunnels can be validated against their IBA record at check-in.
What the integration does (today)
The headline job is straightforward:
Member validation. When a flyer checks in at an FM tunnel, the tunnel sends the IBA the flyer’s member ID and IBA PIN, and the IBA responds with their current standing — name, level, currency status. That’s what stops a non-member from passing themselves off as qualified for advanced flight time.
That’s the part of the integration most members and tunnel operators will ever interact with.
What FuzeMetrix doesn’t (currently) do
The IBA’s FuzeMetrix integration is narrower than the Convergence integration for USA tunnels:
- No custom booking links. FM tunnels don’t have member-specific pricing flows in the way Convergence does.
- No automatic logbook sync. Logbook entries from flights booked through FM tunnels happen through other paths — manual member entry, instructor-side logging — rather than the integration writing entries directly. (Some IBA-internal automation has historically lived here; see Tech docs → External integrations → FuzeMetrix for the full technical contract.)
Trust and authentication
Even with the narrower scope, every payload sent between the IBA and an FM tunnel is signed using HMAC-SHA256 with a shared secret. Both sides verify the signature before acting. A request that fails signature verification is rejected without a hint about what was wrong — deliberately, to avoid leaking information to attackers.
Where this sits in the platform
FuzeMetrix is one of three external booking systems the IBA integrates with — alongside Convergence (USA tunnels, full integration) and Tunn3l (USA + global, coming soon).
