阅读更多关于 What is the minimum width and height Of Facebook Open Graph Images?

I had read that images associated with a given URL in the Facebook open graph had to be greater than 50 x 50 However, when we ran the Facebook Object debugger - we got the following warning: "Tiny og:image: All the images referenced by og:image must be at least 200px in both dimensions. Please check all the images with tag og:image in the given url and ensure that it meets the minimum specification." Our URL is http://www.famousbirthdays.com/people/charlie-chaplin.html and the image does show up under Object Properties Do we need to convert our images to be greater then 200 x 200? Or can we

Allowing multiple domains for 1 Facebook App (like Tumblr)

阅读更多关于 Allowing multiple domains for 1 Facebook App (like Tumblr)

I am trying to get my website validated with the Facebook object debugger and I'm running into the following error: Object at URL ' http://www.example.com/latest ' of type 'smallteaser:teaser' is invalid because the domain 'www.example.com' is not allowed for the specified application id '597566643589666'. This error makes perfect sense since I haven't allowed the example.com domain specific access to the Facebook app. But do I really have to? What I would like to achieve is similar to how Tumblr works when a custom domain is used. Say, for example, the website www.davidslog.com : it has the

Why does Facebook Graph API say my account is non-active?

阅读更多关于 Why does Facebook Graph API say my account is non-active?

We have some code that uses Facebook Open Graph API to display some posts on our home page. It was originally developed by a previous developer and I rewrote it in ASP.NET MVC for our home page (where before it was PHP which I believe was loaded in an iframe). At that time, I used the app ID and secret that were left to me. This has functioned fine for a couple of years. This afternoon, we started getting an error back on our site: "Access to this data is temporarily disabled for non-active accounts due to changes we are making to the Facebook Platform". No sweat. I figured I just needed to

问题 I have an H.264-encoded mp4 file that I'm trying to get embedded into a Facebook post when the page that's serving it is Liked or Shared. My understanding is that I simply need to have the right Open Graph <meta> tags in place on the URL that's being liked/shared. However, I've tried several different sets of <meta> tags and the video is still not embedding when I paste the URL into my Status Update and Post it. It does embed the image from the og:image property, but clicking on the image

问题 I have a Facebook application that users can add to their Facebook business Page(s) as a Page Tab app. It doesn't require any extended permissions for the user.

问题 My website uses Facebook Page API to pull public content from a Facebook page, published by the page owner, to create a dynamic blog with a clear link to the Facebook page. You can see it here in action: https://kc-hrubeho.cz (ctrl+F "Facebook"). Yellow button "Načíst další" works as an AJAX pagination. Sorry for the Czech language, this website unfortunately does not have an English version. I'm using this URL to get JSON object of the page content: https://graph.facebook.com/<PAGE-ID>/feed
