Server-side SDKs - Telnyx

Coverage and release cadence

Telnyx generates the server-side SDKs from the public REST API definition. Resource and method names follow the API model, while each library retains language-specific types and conventions. SDK releases can follow REST API changes at different times. Before adopting a newly released endpoint or field:

Update to the current package release.
Confirm the generated method and model in the language resource map.
Use direct HTTP when an API capability is available before the matching SDK release.

SDK, CLI, or direct HTTP

Interface	Use for
SDK	Application integrations that require typed models, pagination, retries, and structured errors
Telnyx CLI	Shell workflows and automation
Direct HTTP	Endpoint tests, unsupported runtimes, or API capabilities not yet available in an SDK release

The API reference provides endpoint schemas and runnable HTTP and SDK examples.
