Will Facebook charge me to create an app?
I'm wish to use Faceb开发者_StackOverflow社区ook authentication for my website. Facebook says I require an appId. When I want to create an app, it asks for my credit card details. Will they charge me to just to get an appId?
No. You get the app id when you register it at facebook for free.
