Stripe subscription checkout and customer portal integration

I need Stripe's checkout and customer portal integrated with my website. We are a SaaS business. We offer 2 different packages, one monthly, and one annually. I would like there to be a plan picker page on my website and a simple authentication page on my website where the customer can login and they will be redirected to the Stripe-hosted customer portal where they can manage their subscription. Webhooks need to be created.
