Using existing Page as App page

Question

I've got a Facebook app created that is only used for authenticating Facebook Connect and mobile apps (i.e., it has no canvas URL or page tab, etc.). I want to set it up such that this app's page is an existing Facebook page, so that the "via " links when I share content point to this existing Facebook page (currently, it goes to an interstitial that says "You are being linked to the web app", and redirects to our homepage).

If I look in the advanced settings, there is an "App Page" field, but the only option in that field is to create a new page—not the desired effect. Is there a way I can set this manually to an existing page?

P.S. This question showed up in the "similar questions"… it seems this person wanted the same thing I did, but never got a response. :(

Answer 1

I tried the chosen answer but it didn´t work.

The way I did it was this:

1. Categorize your existing page under "App Page" (found under "Brands & Products").
2. Change your page name to mach your App name.
3. Go to your App and select "App Details"
4. Under "Contact Info" you will find "App Page". There you will be able to create a new page or if all went well, select your page from a list.
