Error in call to API function "files/list_folder": request body: could not decode input as JSON

Good morning, I do this request with Arduino:   client.print(String("POST /2/files/list_folder HTTP/1.1\r\n") +                "Host: api.dropboxapi.com" +                "User-Agent: ESP8266/Ard...

    FOUND!
    I used static IP:

    162.125.5.7 

    to access the server.

     

    Probably Drobbox changed the IP a few days ago.

    Now I switched to 

    api.dropboxapi.com
    and everything works like a charm.
     
    Thank you for the support! :)

The /2/files/list_folder endpoint is an "RPC"-style endpoint, meaning it expects the parameters in the request body (not in a request header). 

Please move your parameters to the request body instead of the "Dropbox-API-Arg" header and try again. (The "Dropbox-API-Arg" header is only used for content-upload and content-download -style endpoints.)

Good morning. 

I go right with this call for about 1 year:

 

 
  request = String("POST /2/files/list_folder HTTP/1.1") + "\r\n"
                + "Host: api.dropboxapi.com" + "\r\n"
                + "User-Agent: ESP8266/Arduino_blabla"\r\n"
                + "Authorization: Bearer MYTOKENxxxxx\r\n"
                + "Accept: */*" + "\r\n"
                + "Content-Type: application/json; charset=utf-8" + "\r\n"
                + "Content-Length: " + request_data.length() + "\r\n\r\n"
                + request_data
                ;
 
With this request_data:
request_data = "{\"path\":\"" + MYPATH+ "\"}";
Now, days ago I started getting this error:
Error (4xx)We can't find the page you're looking for.
So, probably some logic is changed serverside...
May you please tell me what do I need to change in my API call?
Thank you.
