🙂 The access point, you are using, guarantees work for size up to 150MB. By the way all single transactions are not guaranteed to support transfer of more than 150MB. Of course, this doesn't mean you can't transfer more! It's just not guaranteed. 😉

If I understand correct, you count backed and server usage as the same. I name it little different. You don't need separate server. "Backend" could be realized as a modification of you code. You have to perform sequentially session endpoints calls (create, append, and finish). "Append" steps could be called concurrently, but not before create and not after finish (that's an option - be careful).

Hope this sheds additional light.

Mubasher Здравко is correct, the issue is that the /2/files/upload endpoint only supports files up to 150 MB. For larger files, you'll need to use upload sessions like Здравко linked to. The upload session endpoints can be called from either a "front-end" or "back-end". A server is not required to make the API calls.
