I am currently making a windows phone 8 silverlight app. In the app we would like to allow the user to pay through paypal or another way of paying. I also looked up the in app payments from the dev center, but did not manage to see a payment with variable values there.
Any help on what to use or examples about how to do this would be greatly appreciated.
Update: according to the policy of the windows phone store you are not alowed to use paypal for example and can nly use Windows Phone in app payments.
This example from visualstudiomagazine should work: http://visualstudiomagazine.com/articles/2013/07/01/in-app-purchasing-for-windows-phone-8.aspx
They explained it very good AND uses the legal way with the Windows Phone SDK 8.0.
Only those payment methods that support Windows store for IAP.
