Native Unity Feature for IAP?

I thought I saw this before but can't seem to find it-- is there a native Unity feature that easily supports IAP for iOS games?

I might be thinking of something else, like the service that supports heat maps, but I thought I saw somewhere there's a switch or something directly in Unity by default to help make IAP super easy. Official Unity Tutorials at least?

 

Unity 5.3 will have this feature, it's in beta for those with unity pro
