Paddle & Lemon Squeezy Integration

My SaaS is running on a “Lovable” stack and I already hold active accounts with both Paddle and Lemon Squeezy. What I need now is a clean, production-ready integration that:

• Lets new and existing users choose a plan and pay through either provider
• Creates and maintains their recurring subscriptions automatically
• Syncs status changes (upgrade, downgrade, cancel, failed payment) back to my app in real time

Please wire up the REST APIs, webhooks and any server-side logic so that revenue lands in my personal payout accounts exactly as Paddle and Lemon Squeezy allow. I will expose the current user, plan and license tables plus a staging environment as soon as we start.

Acceptance will be simple: a test user can subscribe, renew, upgrade and cancel on both gateways, and my dashboard reflects the change instantly. If something is unclear about the “Lovable” codebase, I’ll guide you through it; otherwise feel free to choose the language or framework that gets the job done fastest.
