Question:
Will sending many uploading or downloading requests via the API be throttled? 

Answer: 
By product design, upload and download requests are not subject to throttling. Although these request types are not subjected to throttling, requests such as Account log-ins, for example, would be subjected to throttling. For more information on Cloud Request Throttling, please refer to KBA-36385.

KBA is applicable for Cloud Organizations ONLY.
