An open-source SDK for integrating in-app purchases on Unity

// Your app's code
Adapty.MakePurchase(product, (profile, error) => {
    if(error != null) {
        // handle error
        return;
    }
});

// Your app's code
Adapty.RestorePurchases((profile, error) => {
    if(error != null) {
        // handle the error
    } else {
        // check the access level
    }
});

// Your app's code
Adapty.Identify("YOUR_USER_ID", (error) => {
    if(error == null) {
        // successful identify
    }
});

// Your app's code
var builder = new Adapty.ProfileParameters.Builder()
    .("Profile_Parameters")

Adapty.UpdateProfile(builder.Build(), (error) => {
    if(error != nil) {
        // handle the error
    }
});

// Your app's code
func onAttributionCallback(_ data: [AnyHashable : Any]) {
    Adapty.updateAttribution(data, source: .custom)
}
// The method of getting attribution varies for each particular attribution system
