Is it possible to accept credit card payments or execute PayPal transactions within a Facebook app?
The ideal flow is for users to browse a catalog and complete a purchase all within Facebook. Is this possible?
If so, could you provide guides/tutorials for accomplishing this?
To clarify, our understanding is FB takes 30% of FB Credit purchases. We for this reason plan on offering either PayPal or credit card purchases, not FB Credit purchases. Is it possible to allow FB users to purchase with PP or CC instead of FB Credits? If we’re wrong on the 30% transaction fee, please let us know. Thx!
Thanks!
Starting July 1st 2011 an app on facebook can only perform transactions with Facebook Credits (ignoring in game ‘currency’) . I have no idea where the doc covering this is, I’m not involved in that side of things.
This page https://developers.facebook.com/credits/ has this screen shot

which shows PayPal as an option to pay.
Here’s a link from FishWorld that is explaining the policy on their forums http://www.talltreegames.com/fwf/showthread.php?3807-Facebook-Credits-Switchover-on-July-1st&p=20350#post20350
