Stripe Subscription Checkout Integration

I’m looking for a quick, no-frills Stripe integration that lets visitors subscribe to my service with their credit or debit card. I only need the standard Stripe Checkout flow—no custom form work—so the job is straightforward:

• Configure Stripe for subscription payments (monthly plan already created in my dashboard).
• Embed the ready-made Stripe Checkout button on my site and wire it to the correct price ID.
• Handle success / cancel URLs so users land on the right pages.
• Add basic webhooks for payment-succeeded and subscription-canceled events, logging them or triggering a simple status update in my database.
• Supply clear setup notes so I can swap keys and test in live mode.

The site is already live; I’ll provide repo access, API keys (test mode first), and hosting details. I just need clean, well-commented code and confirmation that a test card can create, renew, and cancel a subscription without issues.
