OAuth2 access token request - Basic authentication not working
I am trying to integrate Dropbox in my webservice. However I decided to use a direct integration instead of any APIs as I need a limited number of functions only and not used to code object orientate...
Thanks! The API is indicating that the request wasn't valid. This particular error message isn't too specific, but it seems to be indicating that the necessary information wasn't given.
Looking through your code, you appear to be sending the parameters as JSON. The /oauth2/token endpoint expects application/x-www-form-urlencoded POST parameters though (with the app key and secret in particular optionally sent in the Authorization header instead).
Please update your code to send the rest of the parameters as application/x-www-form-urlencoded POST parameters instead.

Dropbox StaffWhat is the content of the body for 400 HTTP response? It should contain a more useful error message.

For me however, this is not really useful:
I did a
echo implode($http_response_header);
Returns
HTTP/1.1 400 Bad RequestServer: nginxDate: Fri, 05 Jan 2018 20:33:52 GMTContent-Type: application/jsonConnection: closeX-Dropbox-Request-Id: 864d06461b2bc9f132a4cfa44ca9f2a5X-Frame-Options: DENYContent-Security-Policy: sandbox; frame-ancestors 'none'X-Content-Type-Options: nosniffContent-Disposition: attachment; filename='error'
Maybe, this is more usefull for you :) Thank you in advance!
- Greg-DBThat appears to be the response headers only. Can you print the response body?
