The official PHP SDK documents Composer installation, a PSR-18 HTTP client, API key initialization and Messages API requests.

Scope: These sources establish a customer-side PHP integration. Provider infrastructure impact or remediation for PHP2Shell (CVE-2026-109618 / CVE-2026-109619) remains unverified. SDK availability or minimum PHP requirements are not proof of remediation.

What users should do

Manage the key through environment configuration and test HTTP client compatibility, API errors and timeouts; check the PHP runtime used by the integration.
