|Description||Is there a limit on the total number of callout requests that can be made per 24 hour period or maximum size for ALL callout requests i.e. the amount of data which can be transferred per 24 hour ?|
|Resolution||Answer is No for both of questions. All callout request limits are per transaction and they are NOT calculated on 24 hour basis .
In Apex code developer's guide, different limits are mentioned related to callout however it doesn't specify if it respects the time duration as most of other API related governor limit .
