🎓 Course Enrollment

🔑 Enrollment Process

• Users browse the course catalog and select courses to enroll in.

• For free courses, enrollment is instant upon user action.

• For paid courses, enrollment triggers the transaction/payment process before granting access.

• Users cannot enroll in the same course multiple times.

---

🔄 Backend Flow

• Enrollment request sent to POST /courses/:courseId/enroll

• Server validates user status and course availability

• If payment is required, enrollment waits for successful transaction confirmation

• Enrollment status updated and accessible via user dashboard

---

💳 Payment Integration

• Supported payment gateways: Stripe, PayPal (example)

• Payment process linked directly with enrollment to ensure access only after payment completion

• Transaction records stored and tied to user profiles

---

🛡️ Restrictions & Validations

• Prevent duplicate enrollments

• Enforce prerequisites if applicable (e.g., must complete Course A before enrolling in Course B)

• Verify user subscription status for subscription-based access

---

📨 User Feedback

• Confirmation message upon successful enrollment

• Error messages for failed payments or validation issues

• Email notification (optional) confirming enrollment
