Hi, i am doing a POC project to leverage dropbox store and API provided, to exchange some real time data file. I am thinking to get a client application call dropbox api every couple seconds (or more high frequency) , to verify any change of those data files.
What's the maxium frequency and amount of API call per every user account dropbox can support ? Is there any limitation ?
The Dropbox API does have a general rate limiting system, but we don't have any specific numbers documented (though they're relatively generous). Further, the limits operate on a per-user basis. That being the case, you usually don't need to worry about hitting it in normal use.
Also note that not all 429s and 503s indicate explicit rate limiting, but in any case that you get a 429 or 503 the best practice is to retry the request, respecting the Retry-After header if given in the response, or using an exponential back-off, if not.
