Below Call is successfully executed through Postan Utility then to use with AT commands it is converted to HTTP

--header "Authorization: Bearer <Access Token>" \
--header "Dropbox-API-Arg: {\"path\": \"/Homework/math/Prime_Numbers.txt\"}"HTTP code sent on GSM
POST https://content.dropboxapi.com/2/files/download
Host: content.dropboxapi.com
Authorization: Bearer <Access Token>
Dropbox-API-Arg: {"path": "/File_Name.txt"}
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
when above data is sent below is received response which shows error 404:

Please help me to sort out the issue.
- API calls can fail with a generic HTML page like this if the server doesn't recognize the HTTP request as an API call. Is the sample HTTP request you shared exactly what's actually being sent? If so, it's not valid because it's missing the HTTP version (i.e., "HTTP/1.1") at the end of the first line.
Also, in the sample HTTP request you shared, you're sending an invalid "Content-Type" for this kind of API call. Since /2/files/download doesn't expect anything in the request body, the "Content-Type" header should be omitted anyway. Please try removing that header and try again. (Or, if you can't remove it entirely, please set the value to be an empty string.)
