User quota
A user can create only a limited number of objects in the application. Attempting to create more objects of a certain type than allowed will result in a Quota Exceeded Error (400).
By default a user can add up to 100 accounts to MetaApi and 100 provisioning profiles.
Using Quota API you can get your regional account quotas and also request your regional quotas to be extended. All created non-processed quota update requests can be retrieved.
