API-First Architecture
Every platform function exposed via REST and WebSocket APIs - deep integrations and programmatic traffic control at scale.
What it
means
VoicePro Plus is built API-first. Every action you can perform in the portal - from provisioning DIDs to querying CDRs to updating routing rules - is available via a documented REST API with OpenAPI 3.0 specifications.
Real-time data streams are available via WebSocket connections, enabling partners to build live dashboards, automated alerting systems and programmatic traffic management without polling.
The API supports idempotent operations, pagination, rate limiting with clear headers and comprehensive error responses. Client libraries are available for Python, Node.js, Go and PHP.
How it works
Authentication
OAuth 2.0 with API key fallback. JWT tokens with configurable expiry, scope restrictions and IP allowlisting.
Request Routing
API gateway handles rate limiting, request validation and tenant scoping before forwarding to service layer.
Service Layer
Microservice architecture with independent scaling per service domain (routing, billing, CDR, provisioning).
Response
Structured JSON responses with consistent error codes, pagination metadata and HATEOAS links.
Webhooks
Event-driven webhooks for CDR completion, quality alerts, billing events and provisioning status changes.
Engineered for impact
REST API
Full platform functionality exposed via REST endpoints with OpenAPI 3.0 documentation.
WebSocket Streaming
Real-time CDR, quality and billing event streams via persistent WebSocket connections.
Webhook Events
Configurable webhooks for all platform events with retry logic and delivery confirmation.
Client Libraries
Official client libraries for Python, Node.js, Go and PHP with type-safe interfaces.
Sandbox Environment
Full-featured sandbox for development and testing with simulated traffic and billing.
Rate Limiting
Transparent rate limiting with clear headers showing remaining quota and reset times.
