Mismatched redirect URI
I am using the following link to generate an authorization code for the code flow process:
https://www.dropbox.com/oauth2/authorize?client_id=CLIENT_ID&response_type=code&token_access_type=off...
FrustratedUser3, When you use redirect URI to receive a code, you have to use the same URI as a parameter in the call to /oauth2/token (the 'redirect_uri' parameter). 🙂 In spite this parameter is optional in general, it becomes mandatory with code received through redirect URI and the value should match this URI. As can be seen, it's skipped in your code. 😉 That's where your issue comes from. Here "mismatch" probably means empty/missing doesn't match to the actual.
Good luck.

The oauth2 guide does not make that clear, but you're right. I added redirect_uri to the parameters as follows:
if(isset($code)) { $data[] = "grant_type=authorization_code"; $data[] = "code={$code}"; $data[] = "redirect_uri={$this->cfg->get("siteUrl")}/api/v1/Dropbox/Oauth2"; } else { $data[] = "grant_type=refresh_token"; $data[] = "refresh_token={$this->cfg->get("dropboxRefreshToken")}"; }It works. Thanks.
