Enterprise SMS Integration & Operations
Enterprise SMS remains the universal foundation for transactional alerts, multi-factor authentication, and critical notifications across global mobile networks.

Engineered for Enterprise Integration
- ✓RESTful HTTP endpoints and webhook callback architecture
- ✓Automated GSM-7 and Unicode (UCS-2) character encoding detection
- ✓DLT registration and template ID header compliance support
- ✓Real-time Delivery Receipt (DLR) status processing
- ✓Idempotency keys to prevent duplicate message dispatch
Target Operational Value
- •Universal reach across mobile handsets without requiring app installation
- •Immediate message delivery for time-critical OTPs and security alerts
- •Clear audit logging for regulatory compliance and operational records
- •Predictable queue handling during burst notification events
How the System Operates
API Request
Application posts JSON payload containing recipient number, text body, and idempotency key.
Encoding & Validation
System verifies template compliance, calculates segment count, and checks opt-out registry.
Gateway Dispatch
Message is queued and submitted to the downstream provider network.
DLR Webhook
Network delivery receipt is captured and pushed to your application endpoint.
Standard Protocols
- •JSON over HTTPS POST endpoint with Bearer Token authentication
- •Asynchronous webhook delivery for DLR status callbacks
- •SMPP v3.4 fallback bridge for legacy application integration
- •Pre-built connectors for enterprise software and notification engines
Governance & Privacy
- •TLS 1.3 encryption for all API and webhook transmissions
- •Masking options for sensitive OTP digits in application logs
- •IP whitelisting and API rate limiting per account environment
- •Opt-out and DND (Do Not Disturb) policy enforcement
Observability & Scale
- •Segment counting for multi-part concatenated messages
- •Provider status monitoring and automatic rerouting rules
- •Queue latency tracking and alert thresholds for delayed DLRs
- •Detailed error code mapping for undelivered destinations
