Callable

For developers

Build on Callable with public APIs, webhooks and the Fabric SDKs.

APIs and webhooks

  • REST APIs for messaging, voice and account resources.
  • Webhooks to receive events — inbound messages, delivery receipts, call events — at your own endpoints.
  • App registrations and API keys manage access per application.

Fabric SDKs

Fabric lets you plug your own logic into the live call and message path. SDKs are available for:

  • Rust
  • Node.js
  • Java

A Fabric plugin can inspect a conversation, make routing decisions, call your systems, and drive the AI agent — the building blocks for your own CPaaS use cases.

Getting access

Developer features are managed from your tenant's Developer area — register an app, create keys, and configure webhook endpoints. Contact us to enable developer access on your account.

Full API reference and SDK guides are published here as they are released.
