URI misatch
Hello,
I code a web service in .net/C# and I use the oauth2.
I succeed to do the authorization :
https://www.dropbox.com/1/oauth2/authorize
with params : client_id, state, response_type and redirect_uri
My redirect_uri is a call to another part of my web service.
Inside, I call the next step :
https://api.dropbox.com/1/oauth2/token
with params : code, grant_type, client_id, client_secretand redirect_uri
It fails. The error message is "redirect_uri mismatch". I've checked multiple times and it is the same in my request and in my dropbox app.
I use two differents uri for the first (authorize) and second (token) request (both saved in my dropbox app), is it the problem?
If I use the same uri, how can I distinct the first and second callback ?
Thanks to your help.

Ok, I've understood...
I can use differents redirect_uri, but...
for the "https://www.dropbox.com/1/oauth2/authorize", I must to wait for the callback on redirect_uri.
for the "https://api.dropbox.com/1/oauth2/token", I must do a GetResponse() not wait for the callback over the redirect_uri.
Why must I add a redirect_uri on the second call if it isn't used ?
Thank you to enlighten me.

The
redirect_uriparameter on /oauth2/token is documented as:Only used to validate that it matches the original
/oauth2/authorize, not used to redirect again.I believe that's a security feature of OAuth 2, from the spec here:
