Whop Php Sdk Laravel Package

Initial release — a framework-agnostic PHP SDK for the Whop API, extracted from the Matchable backend.

Added

• WhopApiClient facade exposing the full Whop API across 57 resource groups as public readonly properties (PHP namespace Matchable\Whop).
• PSR-based transport: a PSR-18 client plus PSR-17 factories (auto-discovered via php-http/discovery), with no framework dependency. All HTTP I/O flows through a single HttpTransport chokepoint.
• Typed response DTOs for companies, checkouts, payments, refunds, voids, account links and webhooks; other endpoints return the decoded response array.
• A granular exception hierarchy under the WhopException base — WhopApiException (HTTP 4xx/5xx, carries status code and response body), TransportException, SerializationException, MissingArgumentsException, and WebhookVerificationException — so consumers can catch all SDK failures or a specific subtype.
• WebhookVerifier for Standard Webhooks signature verification, supporting both whsec_ (production) and ws_ (sandbox) secret formats, with raw-input and PSR-7 request overloads.
• Full quality toolchain: PHPStan at level: max, PHP-CS-Fixer, Infection mutation testing, a comprehensive PHPUnit suite, and a GitHub Actions CI workflow.
