How to create a Facebook APP

I have been asked a lot this question lately, mostly because of my really successfull plugin SEO Facebook Comments.

To make the plugin work you need to correctly create a Facebook App and configure all of the needed information in the plugin that you get from the Facebook App.

So here´s how to do it, it´s really easy and straightfoward, especially since the last Facebook Developers redesign:

First, go to the page

It will ask you to login (if you´re not already). Once looged in you´re going to be taken to the following page.

As you can see, In the right top corner of your page you´re going to see a button called + Create New App, just click on it

Insert a nice name for your APP and you can leave the APP NAMESPACE field blank, just agree and then click in CONTINUE. Correctly type the Captcha text ( a challenge sometimes, I know) and just click Continue.

We´re almost done! As you can see in the above picture we already have an App ID and App Secret for our app, now there is just one last thing to do. Click in Website  (attention! It’s not the app domain!) and type the full URL for your domain, taking this blog as an example I would type in the mentioned box.

Now that everything is set just SAVE IT, now go back to your SEO Facebook Comment Admin Page and insert the App ID, App Secret and your facebook e-mail and everything will work just fine ;)

Any doubts or problems feel free to leave a message in the comments bellow.

You have specified an App Domains but have not specified a Site URL or a Mobile Web URL. must be derived from your Site URL or your Mobile Web URL.

Hi! Thank you soooooo much! My Facebook app shows up on every page but my blog. The same thing is happening with my Sharebar. Is there a separate setting to have it show up on certain pages? Here is the web site: Thanks in advance! Joy, DJ

I did everything you has written, comments appear on the site, but on my page in Facebook does not display these comments and the letter to the e-mail does not come, that we can not do that?

I think you should leave the app domain blank and enter the url in the website field

Thanks this looks great… I've installed it, and it works on posts, but not on pages, is there a way to set it to work on selected pages? I've got a music website, and its workings on blog posts, which are news items, but not on pages – which is the way we post reviews and interviews.

How do you get the comment box to appear. Configured everything correctly but no comment box appears on the page and hopefully it should appear below the post.

I have done everything absolutely correct according to instructions above & still app does not allow moderation at https:// I have posted in forum & now here if anyone can help with this ongoing issue I would be so very grateful ~ I also use yoast seo & have the settings in social set to show administrator "currently connected facebook admin" in the drop down choose the name of the app then click update facebook apps, facebook open graph is checked, nothing in frontpage settings, noting in default settings… seo comments settings = correct app id, app secret, admin id ~ add open graph tags is unchecked, post number set to 100 ~ auto approve unchecked…

I've gone through this several times, and FB always rejects my website. It's so frustrating. I'm not sure what to do.

Keeps saying that it's an invalid app id, though it appears correct.

Fabio, I absolutely love you! This tutorial was so fast and easy I can't actually believe it. It worked on the first go and took me like 3 minutes, could have gone faster but I was sooo unsure if I dared try it or not. It looks just brilliant and I am so happy about it :) Thank you, thank you!

How do you get it to work on all pages, comment box only appears on one page?

Per Kinnander

I have followed your instructions but the comment box doesn't appear on my site. I'm not sure about Admin ID, is this a number or is it my FB e-mail? You mention e-mail in your instructions… Does the app need to be approved by the FB team to get the plugin to work? I have submitted it for approval and waiting for a review. Any other thoughts? Any WP settings I need to check?

I have installed SEO Facebook, but I'm not following on how to get it on specific pages. After I've installed the plugin and created my fb app, how do I get the comments on my site? Any help that could be provided would be great.

This is the link to my site which I'm using the plug-in
the problem that I'm having is that there's a yellow box under the facebook comment box and it says the "warning: Unreachable".
I've tried and tried and I can't remove it. HELP PLEASE!

Kinsley Fresh
17 de maio de 2013 0:46

I forgot to add that my comments work and everything function properly. I just hate that Yellow box that is underneath the comment. You can visit to see yourself

to make matters worst the comments just post and they are not in a box like it should be.
