dropbox API call upload limits! confirming some things and feedback

The Dropbox API does have a general rate limiting system that applies to all account types and API calls, but I don't have any specific numbers to share for that, such as the maximum number of calls. This system does not have a strict maximum number exactly, but rather operates on the basis of the rate of calls, i.e., the number of calls per time period per user. 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. I recommend referring to the error documentation and Error Handling Guide, as well as the Performance Guide for more information.

In addition to that general limit though, there is also a specific limit for upload calls to some Dropbox Business team plans of "1 billion API calls/month" for "data transport" noted here. This is a limit on the number of upload API calls that can be made per team per month, for certain Dropbox Business team plans only. This only applies to upload calls, and not other types of calls. You can find more information on this limit in the developer documentation here.

Additionally, as you mentioned, some types of apps (sometimes called "team-linked") can only be linked to teams, not individual accounts, so they can't be accessed by non-team accounts at all, since they offer functionality that only applies to teams. "User-linked" apps can be connected to any account type.

I see that some of these rows could be more clearly described/labeled on that page, so I'll ask the team to see if we can clarify that somehow.
