PHP SDK (Technical Preview)

Technical Preview

The PHP SDK is a technical preview. Its API surface may still evolve and changes may not follow semantic versioning. Pin an exact version if you need stability.

A fully typed PHP client for the Camunda 8 Orchestration Cluster REST API. Fully compliant with the Camunda OpenAPI spec, with a hand-written runtime for authentication, configuration, and job workers.

• Sync and async — CamundaClient (synchronous) and CamundaAsyncClient (promise-based)
• Semantic value objects — distinct types for every identifier, checked at PHPStan level max
• Zero-config — reads CAMUNDA_* environment variables (12-factor style)
• Job workers — long-poll workers with optional pcntl process forking
• OAuth & Basic authentication — pluggable authentication with automatic token management
• PSR standards — PSR-4 autoloading, PSR-18/PSR-7 HTTP via Guzzle
