Save User Score On Cloud, And Showing LeaderBoard According To These Scores

hello,
i just want to save My Game users score on any cloud service, so that i can use these scores globally for making leaderBoard.

If you know about any Third party API, then i want to use it.

thanx in advance.

Complete leaderboard will be managed by App42 platform. These APIs are platform agnostic and support Unity3d.

Have a look at this : Parse Platform
Haven’t used it much yet but it seems easyand powerful, with a reasonable cost
