One API.
Every integration you need.
Stop juggling a dozen provider SDKs and dashboards. OnlyOneAPI unifies SMS, WhatsApp, email and payment gateways behind a single authenticated endpoint, with automatic failover, usage-based billing, and a control panel for every role in your team.
One unified endpoint
Send SMS, WhatsApp or email through the same authenticated API — the routing engine picks the best gateway and fails over automatically if one goes down.
Secure by design
Sanctum-backed sessions, optional HMAC request signing with replay protection, account lockout, and an auto-ban system for abusive IPs — hardened for production from day one.
Real-time visibility
Track every message, payment and invoice from a role-specific dashboard — Super Admin, Employee and Client each see exactly what they need, nothing more.
