Implementing Secure Course Enrollment and Access Control on Squarespace

I am seeking guidance on integrating Articulate courses into my Squarespace platform, with a process that involves learners first completing a Typeform for enrollment and processing payments via Stripe (integrated through Typeform rather than Squarespace). Upon successful registration and payment, learners should be redirected to their designated course. What are the necessary steps to implement this workflow effectively? Additionally, how can I enforce one-time, personalized access linked to each learner's identity to prevent unauthorized reuse of credentials?
