The app ID specified within the “fb:app_id” meta tag was invalid

Question

I tried to enable Facebook Insights for my web. I added my page\'s APP_ID to fb:admins to enable every admin of my page to access Insights when logged

Answer 1

error invalid fb:app_id is sometimes misleading. The account you are using to test this needs to be added into test users list of facebook app. Or try to test using the admin account.

Answer 2

You have to make public you app to start works.

Answer 3

To link Domain Insights to an app rather than a user, you need to use the fb:app_id tag:

<meta property="fb:app_id" content="your_app_id" />

Answer 4

Only personal IDs are allowed in the fb:admins meta tag. Application IDs won't work, even though they are actually valid (in contrary to what the error message says).

Optionally, it may also work with page_id:

<meta property="fb:page_id" content="395450240451647" />

The suggested app_iddidn't work at all :(

Answer 5

You need to clear there cache to test again
