Payment Contracts Laravel Package

tourze/payment-contracts provides a set of framework-agnostic PHP interfaces for building payment integrations. It defines the contracts that gateways, payment providers, and application code implement, so different payment backends can be used interchangeably behind a consistent API.

By depending only on abstractions rather than concrete implementations, the package keeps your payment layer decoupled, testable, and easy to extend with new providers.

• Payment gateway contracts for initiating and handling transactions
• Order and payment state interfaces for uniform status handling
• Provider-agnostic abstractions that avoid vendor lock-in
• PSR-friendly, lightweight design with no heavy dependencies
• Easy mocking in unit tests via simple interface implementations
