API Features

  • RESTful endpoints for all functions
  • Real-time CDR streaming
  • Route management API
  • Sandbox environment for testing
  • Webhook event subscriptions

API-First Means API-Parity

API-first is not a marketing position. It means every feature available in the portal is available through the API. Same data. Same latency. Same capability. If you can click it, you can code it.

No feature lag. No half-implemented endpoints. No “coming soon” placeholders.

Developer Experience

  • OpenAPI 3.0 specification — always current
  • Sandbox — full-feature test environment
  • SDKs — Python, PHP, Node.js
  • Webhook subscriptions — event-driven integration
  • Rate limits — generous, documented, enforced

Integration Patterns

CDR Streaming

Real-time CDR delivery via API or webhook. Stream records as calls complete. No batch downloads. No polling. Your billing system stays current without scheduled imports.

Route Automation

Programmatic route management. Automate quality threshold changes. Script volume rebalancing. Let your systems react to network conditions without human intervention.

Monitoring Integration

Feed Z Line quality metrics into your existing monitoring stack. ASR, PDD, and volume data available via API. Correlate our metrics with your own. Single pane of glass is your choice of glass.

Why We Built It This Way

API documentation that is outdated, incomplete or uninteractive is not documentation — it is a support ticket waiting to happen. We wrote our docs the way we would want to use them: structured, versioned, and testable from the browser. Developer experience is not a feature. It is the product.

What This Means for You

  • Interactive documentation — structured, versioned, testable from the browser
  • Developer experience — integration speed that matches your build schedule
  • Z Line — API-parity, sandbox-first documentation
