Spart PHP SDK
=============

[](#spart-php-sdk)

Official PHP SDK for the [Spart](https://api.spartpay.com) payment-splitting platform.

> ## ⚠️ Verification Status
>
> [](#️-verification-status)
>
> **Create Intent** is fully wire-validated against the live server: request/response shape (`POST /api/intents`, header `x-spart-merchant-api-key`, `Result` envelope unwrap, `intentShortId` / `checkoutUrl`), happy path, replay idempotency, the 400 validation path, and the 401 auth path are all covered by the E2E suite (see "Running E2E tests" below).
>
> **Webhook signature scheme** is wire-validated end-to-end: the SDK's `SignatureVerifier` and the server's `WebhookSignatureBuilder` agree on HMAC-SHA256 over `"{t}.{body}"` with header `t=,v1=`. This is exercised by the `SignatureVerifierTest` self-sign loop in the E2E suite.
>
> **Webhook envelope DTOs** (`IntentEnvelopeData`, `OrderEnvelopeData`, `PaymentEnvelopeData`, `TestEnvelopeData`) and the `EventType` enum values are still **not** wire-validated against real webhook deliveries. Capturing a real-delivery envelope is tracked as a follow-up issue and may surface field-name or shape adjustments before the webhook surface is considered stable.
