Stripe

• Stripe Backend for python
• It is necessary to handle strip checkout sessions, the client (frontend) only forwards the request.

Prerequisite

• Have a working flask API see Flask.md

Code

• Code to create POST endpoint using Stripe
• This will redirect user to a checkout page, and redirect back to your application on successful payment (or not).
• all the keys should be generated by your stripe account in their site. (Except for your secret key which you will generate yourself.)
• see Token Validation

                {
                    # Provide the exact Price ID (for example, pr_1234) of the product you want to sell
                    'price': PRODUCT_KEY,
