You might see that the Dropbox Community team have been busy working on some major updates to the Community itself! So, here is some info on what’s changed, what’s staying the same and what you can expect from the Dropbox Community overall.

measuring the amount of file uploaded
Say I'd got a 300MB file, the example docs state to read the file to be uploaded in one gulp since an append method is not available(https://www.dropboxforum.com/t5/API-support/How-to-append-to-existing-file/m-p/271603/highlight/true#M16083) , via the api(or any method possible for which the file can be uploaded in chunks) is there a api call that tells us the amount of file uploaded so that we can measure the status to construct something like a progressbar for our applications?

There isn't a way to check the progress of an in-process upload remotely via the API. Depending on what, if any, SDK or library you're using though, there may be a local progress callback available though. (For example, here's a sample of using that in the Objective-C SDK.) Check the documentation for whatever SDK/library, if any, you're using for more information.
Note that for files larger than 150 MB though, you should be using "upload sessions", which do have you upload files in pieces:
https://www.dropbox.com/developers/documentation/http/documentation#files-upload_session-start
https://www.dropbox.com/developers/documentation/http/documentation#files-upload_session-append_v2
https://www.dropbox.com/developers/documentation/http/documentation#files-upload_session-finishIn that way, you can track (again, from the API client side) how much you've uploaded, in between calls.
Yes, I actually found out about the upload session recently, but it's giving me errors. For example, I'm using this core logic for upload sessions, but I'm getting a connection timeout error or something like API error.
