For web you have a wide range of possibilities to connect existing payment systems and integrate paywalls on different levels. 

Purple DS does not have its own paywall for web. The app offers the option of subscribing to iTunes and Google Play or to make individual purchases. 

It is also possible to connect existing print entitlements via our standard API. 

The connection of different entitlement systems such as CDS Global or Palm Coast are already part of the standard product.
