mobile authentication

[daniel...@gmail.com]

Hello,

I'm trying to create a mobile app for soundcloud, and I wish to use
this : http://developers.soundcloud.com/docs/api/authentication#user-credentials-flow
to manage the authentication stuff.
But it looks like I can't be able to use it, following the instruction
on the site, I get this response:
{"error":"invalid_grant"}
Could you please explain what I'm doing wrong?
Thanks.


Regards,
Daniele.

Hi Daniele,

Could be a number of things, would you be able to post a snippet of your code either in an email or using something like pastebin.com?  

Cheers,

there is no code yet, I'm simply trying this:

$ curl "https://api.soundcloud.com/oauth2/token" \
-d 'client_id=04u7h-cl13n7-1d' \
-d 'client_secret=04u7h-cl13n7-53cr37' \
-d 'grant_type=password' \
-d 'username=user...@example.com' \
-d 'password=p455w0rd'

just copy&paste with the necessary modifications, nothing more.

Hi Daniele,

Everything looks fine there. I copied and pasted the example, modified the client id, secret, username and password and was able to get an access token. Have you verified that you're using the correct values? The invalid_grant error message would indicate that you've got an incorrect username or password.

you are right, the problem was that my password contains some whitespaces that needed to be escaped (or something similar).
Thanks for your help.
