I can no longer upload files

Question

Hi all,&nbsp;For some time now I have not been able to upload my files via the HTTP API.The file/upload or file/get_temporary_upload_link gives me a 404 error even though it worked perfectly until now.&nbsp;If I do CURL tests then everything works perfectly, so I suspect an unsupported header. Here is the list of headers on my HTTP request (I use python/requests to do this):&nbsp;&nbsp;Headers: {'User-Agent': 'python-requests/2.25.1', 'Accept-Encoding': 'gzip, deflate', 'Accept': '*/*', 'Connection': 'keep-alive', 'Content-Type': 'application/octet-stream', 'Dropbox-API-Arg': '{"mode":"overwrite","path":"/Sans nom 1.odt","autorename":false,"mute":false,"strict_conflict":false}', 'Content-Length': '473722', 'Authorization': 'Bearer sl.B_3Hk1dv...'}&nbsp;&nbsp;I'll try adding these headers to CURL to see if that's where it comes from, but I'm interested in any good information.&nbsp;Thanks.

Thanks for following up and sharing that. In your Python code, you're using the "PUT" method, via the ".put" call, however the /2/files/upload endpoint expects a "POST". That would be ".post" in the requests library.

Ok the CURL header that seems to be no longer supported is:&nbsp;&nbsp;--header "Accept-Encoding: gzip, deflate" \&nbsp;&nbsp;How is this possible?

I just gave this a try myself, but I'm not getting back a 404 error when I use that header. Can you share the full request and response for this issue so we can take a look? If you're using curl, use the -v option to enable verbose mode. Please redact your access token though. Thanks in advance!

Hi Greg,&nbsp;No, it doesn't come from the headers, sorry.I can get this Curl query to work correctly:&nbsp;curl -X POST https://content.dropboxapi.com/2/files/upload \
    --header "Authorization: Bearer sl.B_2..." \
    --header "Dropbox-API-Arg: {\"autorename\":false,\"mode\":\"overwrite\",\"mute\":false,\"path\":\"/Test Dropbox.odt\",\"strict_conflict\":false}" \
    --header "User-Agent: python-requests/2.25.1" \
    --header "Accept-Encoding: gzip, deflate" \
    --header "Accept: */*" \
    --header "Connection: keep-alive" \
    --header "Content-Type: application/octet-stream" \
    --write-out "%{http_code}
" \
    --data-binary "@/home/prrvchr/Test Dropbox.odt"&nbsp;&nbsp;On the other hand, if I use Python/Requests instead of Curl, it gives me a 404:&nbsp;import requests

url = 'https://content.dropboxapi.com/2/files/upload'
headers = {'Content-Type': 'application/octet-stream',
           'Dropbox-API-Arg': '{"autorename": false, "mode": "overwrite", "mute": false, "path": "/Test Dropbox.odt", "strict_conflict": false}',
           'Authorization': 'Bearer sl.B_2...'}
data = open('/home/prrvchr/Test Dropbox.odt', 'rb')
response = requests.put(url, headers=headers, data=data)
print("Status Code: %s" % response.status_code)
response.close()
data.close()&nbsp;&nbsp;I don't see why...

Thanks Greg for finding my mistakes...&nbsp;But this code that you just corrected was only created to test the file/get_temporary_upload_link command which has stopped working for some time.&nbsp;And I just found what was preventing it from working, it is apparently the temporary upload link which no longer supports an Authorization headers which was there by mistake.&nbsp;Here is an example of code that worked and no longer works, it now returns a status code 500:&nbsp;import requests

url = 'https://api.dropboxapi.com/2/files/get_temporary_upload_link'
token = 'Bearer sl.B_...'
headers = {'Authorization': token}
json = {'commit_info': {'path': '/Test Dropbox.odt',
                        'mode': 'overwrite'},
        'duration': 3600}
response = requests.post(url, headers=headers, json=json)
if not response.ok:
    print("Request on Url: %s give Status Code: %s" % (url, response.status_code))
    response.close()
else:
    url = response.json().get('link')
    response.close()
    headers = {'Content-Type': 'application/octet-stream',
               'Authorization': token}
    data = open('/home/prrvchr/Test Dropbox.odt', 'rb')
    response = requests.post(url, headers=headers, data=data)
    print("Request on Url: %s give Status Code: %s" % (url, response.status_code))
    response.close()
    data.close()&nbsp;&nbsp;Anyway, all these problems were caused by a mistake in my code and now it is fixed.&nbsp;Thanks for your help and I think we can close.
