In-App Purchase & Paywall — In-app purchase and paywall infrastructure sells upgrades inside the product itself — mobile store purchases, feature paywalls, and one-tap plan changes. It reads plans and prices from the catalog, and each purchase updates entitlements and the billing record without human touch.
In-App Purchase & Paywall lives in the Digital Commerce phase of Win the Deal — the stage where you quote, negotiate, and close on governed pricing. In the corpus tool index this phase maps to the Payments and Billingcategories.
