I’ve already launched several apps and now want to let customers pre-pay for usage by buying a bundle of tokens on my Squarespace site, with Stripe handling the checkout. After purchase, those tokens should immediately appear on the customer’s account inside each of my published apps, where they’ll be debited as the user consumes features. Here’s the flow I have in mind: 1. Visitor selects a token amount on a Squarespace 'buy credits' page and pays once through Stripe Checkout or Payment Links. 2. A secure webhook or custom API call translates that successful payment into an updated token balance in my backend. 3. When the balance is refreshed the user can start spending tokens without delay. 4. When the user tries to use one of the online tools (AI generator), the code checks the users account for sufficient credits. If successful the app generates the media. If there is insufficient credits/tokens the web-tool declines the request to generate. Deliverables • Squarespace checkout component wired to Stripe for one-time token purchases • Backend logic to create / update token balances and expose them through an authenticated endpoint my apps can call • Basic admin view or CSV export so I can see who bought what and how many tokens remain • Clear setup notes so I can maintain or extend the system later If you’ve connected Squarespace, Stripe, and a mobile backend before—and can move quickly—let’s talk.
