checkout-and-post-purchase
Stripe checkout, return URLs, checkout_session_id, and applying entitlements after payment.
Stripe checkout
AI Studio purchases typically complete through Stripe Checkout. You may be redirected away from the app and back after authorization.
Return URL and session id
Successful returns often append checkout_session_id to the URL. The server uses that session to apply entitlements—for example unlocking Shortlist Pack or attaching a Logo Kit ticket.
Pending states
If you close the browser before returning, check billing history or relaunch the workspace; support can reconcile stuck states with your session id.
