Relay Mono Connector Payunity Bundle Laravel Package

Product Decisions This Supports

• Legacy System Migration: If your product relies on PayUnity for payments and needs to transition to a new payment gateway due to PayUnity’s shutdown, this package could serve as a reference implementation for building a custom connector for Relay (or another API gateway).
• Technical Debt Mitigation: If your team is already using Laravel/PHP and Relay for API routing, this package’s architecture (mono-bundle pattern) could inform how to integrate a new payment provider with minimal reinvention.
• Proof of Concept (PoC): For evaluating whether Relay’s mono-bundle architecture is viable for your stack before committing to a custom solution.
• Avoid Rebuilding from Scratch: If you’re replacing PayUnity and need a starting point for authentication, webhook handling, or API routing logic (even if the package itself is deprecated).
• Open-Source Contribution: If your team wants to fork and adapt this for a new payment provider (e.g., Stripe, Adyen) under a more permissive license.

When to Consider This Package

• Do NOT use this package directly if:
  • PayUnity is still operational for your use case (use their official SDK instead).
  • You need active maintenance, security patches, or compliance updates (AGPL-3.0 may also impose licensing risks).
  • Your team lacks the bandwidth to audit, fork, or replace deprecated dependencies.
  • You’re evaluating modern alternatives (e.g., Laravel Cashier, Omnipay, or dedicated payment SDKs like Stripe/PayPal).
• Consider this package only if:
  • You’re migrating away from PayUnity and need a Laravel/Relay-specific blueprint for connector logic.
  • Your team has experience with Relay’s mono-bundle pattern and can extend it for a new provider.
  • You’re building a custom payment integration and want to leverage Relay’s routing/validation layers.
  • The package’s code structure (e.g., webhook handling, API client abstraction) aligns with your needs despite its obsolescence.

How to Pitch It (Stakeholders)

For Executives (Business Leaders)

"PayUnity’s shutdown forces us to migrate our payment infrastructure. This deprecated Laravel package offers a reference implementation for integrating Relay—our existing API gateway—with payment providers. While we won’t use it directly, it gives us a head start on building a custom connector for our new payment partner (e.g., Stripe, Adyen) without reinventing the wheel. The risk is low: we’ll audit the code, fork it if useful, and avoid technical debt by reusing Relay’s routing and validation logic. This aligns with our goal to reduce vendor lock-in while keeping our stack consistent."

For Engineering (Tech Leads/Devs)

*"This package is a legacy PayUnity connector for Relay, but its mono-bundle architecture could save us weeks of work. Key takeaways:

• Relay Integration: Shows how to plug a payment provider into Relay’s API gateway (useful if we’re keeping Relay).
• Webhook/Event Handling: Includes patterns for processing payment callbacks (e.g., PayUnityWebhookHandler).
• API Client Abstraction: Demonstrates how to wrap provider SDKs (e.g., PayUnityClient) for consistency. Proposal: Use this as a starting point for our new payment connector. We’ll:

1. Audit the code for security/design flaws.
2. Fork it and replace PayUnity-specific logic with our target provider’s SDK.
3. Extend Relay’s mono-bundle to support our new workflows. Alternatives: Building from scratch or using Omnipay would take longer and lack Relay-specific optimizations."*

Critical Note: Emphasize that this is a starting point, not a production-ready solution. Highlight the need for a custom fork and compliance review (AGPL-3.0).
