Intelligent failover

Adaptive Routing™

Ensure optimum delivery by rerouting messages proactively around congestion — like GPS for your SMS.

Flexible implementation

Choose from three Verify models: Verify Success, Verify Request or Verify Conversion.

Verify Success

Our full-service, per-conversion only model allows you to start authenticating phone numbers across the globe with just a few lines of code. Verify manages the PIN code with auto-failover to additional channels when needed.

Verify Request

Our per-request model allows our customers to manage their PIN code and customise the failover sequence to additional channels.
