I'm looking at GameSparks as a possible solution but I was wondering if there are any real world IAP payment options for Unity WebGL builds ? I was hoping for Amazon Pay, PayPal, Facebook Payments or even a way to integrate with Xsolla's system for multiple payment options but I can't see anything suitable in the documentation.
Can anyone advise a potential solution ? Mobile (and presumably console later on) are fine, I've seen discussion for Steam integration for standalone PC but it would be nice if I could offer the same features in my WebGL build. At the moment it seems that there's no way to monetize on this format using GameSparks. Am I wrong ?
As an aside, since GameSparks has now been purchased by Amazon I'd say adding Amazon Pay support is a no-brainer ;)
