Svea PHP SDKModern PHP SDK for Svea Checkout

Checkout, Payment Admin, Subscriptions & Webhooks — fluent, fully tested, Laravel-ready.

🛒

Full API coverage

Checkout, Payment Admin (deliver, cancel, credit), Webhook Subscriptions, and inbound webhook verification — all four Svea API surfaces in one package.

🎯

Fluent & strict

Final readonly value objects, fluent builders with when() / unless(), typed exceptions, PHPStan level 6, full strict_types — built for PHP 8.2, 8.3, 8.4, 8.5.

🪄

Two ways to build any request

Pass a fully constructed value object — or a closure that mutates a pre-built builder. Loops, conditionals and composition come for free with the fluent callback style.

🧪

First-class testing

Svea::fake() mirrors Laravel's Http::fake() — assert calls, seed responses, prevent stray requests. Plus full Guzzle MockHandler examples.

⚡

Production-ready transport

HMAC-SHA512 auth, opt-in exponential backoff retries on 429/5xx, idempotency keys for safe queue retries, async task polling.

🪶

Framework-agnostic core

The core has zero Laravel dependencies. Use it in Symfony, plain PHP, or anywhere. Laravel integration (service provider, facade, Artisan commands) ships separately.
