Selling Virtual Goods flowHi,
When start_payment() function is called and user press purchase:
1. the transaction is sent to the Papaya server to be authorized
2. Server-Server Callback (Papaya Social Game Engine SDK Manual page 44) will happen
3. a paycallback, from start_payment(), will be called
Is this correct?
In point 2, do you expect some special response from my server or it's just an info about purchase?
We don't expect special response from your server. the main point of server-server communication is that both developer and Papaya can be on same page in terms of purchase history.
