API Error Code: 191

Question

yep, getting the 191 error. I've researched and found this question to be helpful: Facebook API error 191

My URL looks like:

https://www.facebook.com/dialog/oauth?client_id=&redirect_uri=http%3a%2f%2flocalhost%2fFb.201109Birthday%2fOAuth2.aspx

However, I get an error:

API Error Code: 191 API Error Description: The specified URL is not owned by the application Error Message: Invalid redirect_uri: Given URL is not allowed by the Application configuration.

I've read everywhere that the urls must match up to what's listed in the application's setting page. I've got

• App Domain = localhost
• Canvas Url = http://localhost/Fb.201109Birthday/Birthday.aspx?
• Secure Canvas Url = http://localhost/Fb.201109Birthday/Birthday.aspx?

I've also tried local.facebook-apps.com (replaced "localhost" everywhere above with "local.facebook-apps.com") with a hosts file entry to point to 127.0.0.1. But all of these scenarios still give the 191.

Answer 1

Remove the Birthday.aspx from the Canvas URLs.

Answer 2

I was also getting this error when i created a facebook application that was going to be installed onto a tab on a fan page. It turns out that when i first created my facebook application i only filled out the section for "Page Tab" but i didn't fill out the section for "App on Facebook".

i didn't fill out the App on Facebook section because i didn't want users trying to add the app from the app profile page. Anyway, it turns out that by not filling out the App on Facebook section and adding a canvas URL and secure canvas URL i was getting the Error: 191 when trying to make a javascript call to FB.Login().

Once i filled out the App on Facebook section the error went away.
