Getting Error 100 - Invalid Parameter from facebook.auth.getSession

[Andrew Laffoon]

Hi All,

I downloaded the sample ManualFacebookTest.mxml, and it does not work
for me. I tried using my own api_key and secret, and I even tried the
supplied sample api_key and secret. Still, it does not work. I am
able to get the correct auth_token from the response, but it still
fails. Does anybody have any idea how to fix this?

Thanks,

Guys,

This error was a result of my auth_token methodology. I was using the
auth_token from the Auth.createToken() method, but I should have been
using the auth_token that gets posted to my callback URL after the
login screen.

It is not a bug.

Any solutions to this? I keep getting this error too and I'm copying/
pasting my APIKey and Secret directly into the sample code.

Here's some help. I've written a few classes to log you in
automatically. It shows how to authenticate a session and u can roll
from there.
You will need the API installed and call FacebookApp as your main
class (I use Flex 2 SDK and FDT to do my coding).

Run the main class. The flash window will launch. This will then
automatically take you to facebook in your browser. If you are not
logged it Facebook will prompt u to do so. After logging in it'll jump
you back to you callback url as specified in your Facebook Application
setting in Facebook.

You might require the swf you have made to be running on a web server. i.e.
http://localhost/facebookApp/index.html

Make sure u set your api_key and secret in the FacebookConfig class.

I am having the same problem

I *am* using the auth_token passed to me from the facebook login url -
how do you pass it in to the facebook object? Like this?

fb = facebook.Facebook('abcdefghik', 'xxxabcdefghik', 'zzzabcdefghik')

(all values assumed of course) - Does any argument need to be a name/
value pair?

Thanks

Sami
