When I retrieve my facebook status through facebook API, using status.get, the informations comes in the form of
[
{
"message": "Does anyone here knows how to disappear and reappear again after a few months??",
"time": 1282146230,
"status_id": 00000000000000,
"source": 2915120374,
"uid": 000000000
},
{
"message": "Blah blah and blah",
"time": 1282073572,
"status_id": 00000000000000,
"source": 2915120374,
"uid": 000000000
}
]
I want to format the information using css and display the updates on my blog. How do I extract the info from the above retrieved format so that I can use it on my php page and use css to style the updates??
This is called JSON format. If you scroll to the bottom on the JSON site you will find a huge list of available libraries for pretty much every language.

i am trying to open a specific messenger page and trigger a dialog to display carousels based on the parameters that my users entered on my website.
i am leveraging the m.me link to open my messenger page (where my botframeowrk bot is deployed). After opening the page I am not able to invoke a dialog.
How can I achieve this ???
I went through the Ms Botframework V4 docs and didn't find any mention of channel specific trigger.I want to pass 4 parameters to my Bot from the website and then further make an api call in the dialog that i will invoke to display results.
Thanks in Advance.
You need to enable Messaging Referrals in the Facebook Developer portal to use m.me links. In the portal, click on the settings blade on the left, scroll down to webhooks, and click edit events. A window should pop up where you can enable messaging_referrals.
Facebook only lets you add the ref parameter to the m.me link, so to send additional data to the bot using this link, you will have to encode the values in the ref parameter and parse the data on the bot side - I would recommend using a separator value like a comma or a slash to organize your data.
https://m.me/<PAGE_NAME>?ref=my,additional,data
The event will be send to the bot as a message activity with a referral attribute where you can grab your data.
m.me link bot activity

My app needs to get data facebook scrapes from URLs. Up until now we were getting it using
POST /?id={object-instance-id or object-url}&scrape=true
Which is detailed in updating object section in https://developers.facebook.com/docs/sharing/opengraph/using-objects
For example
POST /?id=http://google.com
{
"url": "http://www.google.com/",
"type": "website",
"title": "Google",
"image": [
{
"url": "http://www.google.com/images/branding/googleg/1x/googleg_standard_color_128dp.png"
}
],
"description": "Search the world's information, including webpages, images, videos and more. Google has many special features to help you find exactly what you're looking for.",
"updated_time": "2015-10-06T11:34:58+0000",
"id": "381702034999"
}
Notice image section.
Unfortunately if og tags are configured wrongly on the server
POST /?id=http://some.page.with.bad.tags.com
{
"error": {
"message": "Invalid parameter",
"type": "FacebookApiException",
"code": 100,
"error_subcode": 1611016,
"is_transient": false,
"error_user_title": "Object Invalid Value",
"error_user_msg": "Object at URL 'http://some.page.with.bad.tags' of type '' is invalid because the given value '/some-bad-value' for property 'og:url' could not be parsed as type 'url'.",
"fbtrace_id": "abcabcabc"
}
}
Which returns nothing interesting.
Attempt to GET the url returns this:
{
"og_object": {
"id": "381702034999",
"description": "Search the world's information, including webpages, images, videos and more. Google has many special features to help you find exactly what you're looking for.",
"title": "Google",
"type": "website",
"updated_time": "2015-10-06T11:40:04+0000",
"url": "http://www.google.com/"
},
"share": {
"comment_count": 2,
"share_count": 13494003
},
"id": "http://www.google.com"
}
Which misses image section. I cannot find in the documentation any way to retrieve result with images without using POST /?id={url}, but that fails on any errors in og tags.
GET /{ObjectId}
returns only type and created_time
Entering the same broken link in https://developers.facebook.com/tools/debug/ results in page which contains image, description, title and captions for the page. Which I need. So it means facebook stores them, even though page has wrong tags, but I need a way to fetch them. Unfortunatelly I cannot provide link for broken url due to NDA, and I couldn't find other page with broken tags.
If the page contains invalid Open Graph markup this seems expected, also do not confuse the Graph API with some sort of datasource or a scraping service you can utilize to generate the preview for web content.
If Facebook , for whatever reason, can't parse the Open Graph tags of a URL it will try to make a good guess based on the content of the page (large junks of text, images it finds, title tags etc.) to build the preview so you might get some sort of data back from GET /{object-id} which can just be a guess instead of actual og:.. data.
In case you really need a more or less failsafe solution, you could build your own scraper that looks for Open Graph tags.
I'm writing an app which requires me to determine whether I show the fb "like" button or not. fb profiles don't have "likes" but pages do. any recommendations on how I can programatically differentiate between a fb profile and a fb page? the only input i get from the user is the fb profile/page URL and based on that I need to determine whether its a page or a profile and then display the like button.
thx,
Yes, you can look at the type attribute of the returned JSON. For example, take a look at actual, redacted Graph API responses that I receive for a user and a page:
//This is JSON for a user
//Call to https://graph.facebook.com/123456789
{
"id": "123456789",
"name": "Sean Hill",
"first_name": "Sean",
"last_name": "Hill",
//more attributes
"type": "user" // <--- This one
}
vs
//This is JSON for a page
//Call to https://graph.facebook.com/thesolusean
{
"id": "323796444951",
"name": "Solusean",
"picture": "https://fbcdn-profile-a.akamaihd.net/hprofile-ak-snc4/50290_323796444951_3601170_s.jpg",
"link": "https://www.facebook.com/thesolusean",
"likes": 28,
// more attributes
"type": "page" // <---- This one
}
Without knowing which programming language you're using, this is the best answer I can give.
So far it seems the only quick way to know whether given profile is page or actual user is by looking at category attribute. If this attribute is present then its a page otherwise it could be user. FB reference docs doesn't seem to have any clear guidance (see https://developers.facebook.com/docs/graph-api/reference/profile). In additional most of the APIs that return profile as part of other response only includes partial information of id, name and category:
"from": {
"category": "Magazine",
"name": "Astronomy Magazine",
"id": "108218329601"
},
Note: I'm confused by #Sean Hill's answer. There is no type attribute in profile objects.
I'm making a webpage/SEO checking page, where I can put in a URL and it will tell me various facts about the page.
I'd like to be able to tell if there is a Facebook page associated with the URL. Is this possible using the API, or by other means?
For instance, https://www.facebook.com/focalstrategy links to http://www.focalstrategy.com/ on the info tab – is there a way to go the other way and enter the URL and find the page(s)?
(Bonus points – anyone know of a way to do the same for Twitter accounts)
I don't think this is possible. Using the API, you can retrieve info about the url:
http://graph.facebook.com/?id=http://www.focalstrategy.com/
Would return:
{
"id": "http://www.focalstrategy.com/",
"shares": 38
}
Now I'm note sure if using the Open Graph Meta Tags would help return more data (still not what you need), but here is my website info without trailing slash:
http://graph.facebook.com/?id=http://www.masteringapi.com
Would return:
{
"id": "109784969102047",
"name": "MasteringAPI.com",
"picture": "http://profile.ak.fbcdn.net/hprofile-ak-snc4/276619_109784969102047_474156823_s.jpg",
"link": "http://www.masteringapi.com/",
"likes": 25,
"category": "Website",
"website": "http://www.masteringapi.com",
"description": "Master Facebook, Google and Twitter APIs! Learn Facebook Application Development Now!",
"can_post": true
}
I am developing a social media monitoring service. And I'm now trying to fetch the posts and comments from a certain group of users.
However, I found that a lot of empty posts are fetched by Graph API https://graph.facebook.com/somebodysuid/posts?access_token=xxxx . That is, a lot of posts are of the following form:
`{
"id": "somebodysuid_xxxxxxxxxxxx",
"from": {
"name": "XXX YYY AAA",
"id": "somebodysuid"
},
"type": "status",
"created_time": "2011-08-03T05:49:11+0000",
"updated_time": "2011-08-03T05:49:11+0000",
"comments": {
"count": 0
}
},
{
"id": "somebodysuid_yyyyyyyyyyyyyyy",
"from": {
"name": "XXX YYY AAA",
"id": "somebodysuid"
},
"type": "status",
"created_time": "2011-07-24T23:31:35+0000",
"updated_time": "2011-07-24T23:31:35+0000",
"comments": {
"count": 0
}
},
Through these are indeed posts, but they're totally useless. The worst thing is, half of the data I fetched are of this kind....
Can somebody please explain why so many empty posts would the API fetch? Can this be solve by any way?
Those posts are probably updates made through the "new share form" where users can tag places and friends and attach geo-locations without adding any additional message.
Those type of posts are typed as "status" but graph api does not return the other meta-datas yet (location, tags, etc...) that's why you see them empty.
Let's hope FB will fix that quickly :(
I think FB has started to add activity information that appears on a Facebook web page, such as "John Doe is now friends with Tom Jones", or "Fred Smith and 2 others have changed their profile image". This activity information is a) incomplete in the returned feed and b) does odd things when you look for more information by asking the graph API for detail based on the posts id field.
My current guess is that this is new functionality for the feed - I have been unable to find documentation or mention of it. They are very difficult to process at this time, since they look like other things and contain no identifying detail.
Here is the question I posted looking for help. It give another example:
Facebook graph "user/home" feed now contains activities as post items that are difficult to identify
