bad error 400 on every API request!

[MarkusF]

Hi,

I´ve tired to implement the API upload and download in M5STack (Arduino).

On every request I get an bad error 400!

I´ve copied the header from API explorer, where all works fine!

Can anyone help please what does it mean, and what is the problem!?

my header and response:

POST /2/files/download
Host: https://content.dropboxapi.com
User-Agent: api-explorer-client
Authorization: Bearer xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx
Dropbox-API-Arg: {"path":"/M5Stack_test/db_01.txt"}
