According this question and the official documentation on Signed Request, there should be within the encoded JSON payload a user object with an age object for the age range of the user.
However, when I decode the signature received through the JS SDK, I only have values for user_id, code, and a couple others, but no user object let alone age range. I've verified this in a stand-alone "connect" environment, as well as in a "tab application" environment. Further, when I test the JS SDK at the Test Console I see no user object either.
How can I get the user age range using just the JS SDK?
From the link
you referred,
Fields and Values
A signed_request is simply a data transfer mechanism and does not
imply any defined structure or format of data carried in the request.
However, within the Facebook Platform, the JSON object payload may
contain some of the following fields and values:
Notice the may.
There's no way you can fetch age or age range through js sdk, without
getting permission
.
p.s. I havent tested in canvas app, but in page tabs, the signed request contains the age range but only when user likes your page :)
I think you should get permission and caculate bitrthday date.

I am trying to work with the Vimeo API and I cannot figure out how to access the ondemand data.
The endpoint and parameters in the docs require an ondemand_id to work correctly. I assumed this ID would come from any official ondemand page within Vimeo. But whenever I search the ondemand pages of Vimeo and click on a resource, the URL does not contain any numerical ID.
It only contains the root path for the Vimeo website with /ondemand_page_name at the end. This value cannot be the ID since it is a string and not a number. I have looked through the entire page plenty of different times to try to find the ID but cannot seem to find it.
For example, when you visit a normal video page on Vimeo, the URL looks something like this:
https://vimeo.com/272976101
where the number 272976101 is the video_id that can be used within the API to get all the data about this particular video. Instead of this format, the ondemand pages have the format:
https://vimeo.com/ondemand/nebula
where there is no numerical ID within the URL. This is the issue I am having. How would I retrieve the public data about this ondemand page throught the API.
I feel like there may be a very simple solution/explanation to this issue and any help would be much appreciated.
Also, right now I am not using any SDK to access this data. I am strictly trying to figure out how the API works through the built-in client provided within the documentation.
It's undocumented, but you can use the On Demand custom url path as the ondemand_id.
So for your On Demand video at https://vimeo.com/ondemand/nebula, you can make an API request to this path: https://api.vimeo.com/ondemand/pages/nebula.
In the response, you'll see the "uri" value "/ondemand/pages/203314", which you can log on your end and use as the ondemand_id instead of /nebula.
Also note, this should be the same URL as your On Demand settings page: https://vimeo.com/ondemand/203314/settings
I hope this information helps!
I am trying to retrieve my app campaigns and their associated apps with their events via my advertiser account.
The problem is that I am unable to find a unique identifier for my app in the API response.
For example the query below will get me the 'action_target_id'. This would either equal my AppId or another numeric string which I don't know what is. I am confused, does it mean I have two AppIds?
act_<AD_ACCOUNT_ID>/reportstats?time_interval={"day_start":{"day":"01","month":"03","year":"2014"},"day_stop":{"day":"07","month":"04","year":"2015"}}&data_columns=['adgroup_id', 'actions','action_target_id','action_target_name','campaign_name']&actions_group_by=['action_device','action_type']&format=json&async=true
What are 'action_target_id' and 'action_target_name' meant to represent (in the context of running a campaign for a mobile app)? I cannot seem to find a clear explanation for this in the API doc.
The applications/developer edge will return applications your account has access to.
As for your second question, the action_target_id and action_target_name are not always your application. It depends on what the action specs of each campaign is, if even set. An 'action spec' is a FB format for defining relationships between an ad and various objects for various purposes. More about that at https://developers.facebook.com/docs/marketing-api/intro-action-specs
In your case, the action spec in the context of a mobile app ad campaign will probably be the FB application. See also default conversion spec and default tracking spec.

Is there a size limitation on Facebook App Id? How many characters will this usually be?
There is no fixed size for any ID or Token in Facebook.
Click here for source quoted bellow
Object IDs
Each node has a unique ID which is used to access it via the Graph API. We specifically do not document any node/object ID structure or format because it is extremely likely to change over time and apps should not make assumptions based on current structure.
This extends to access tokens as well.
I want to build a dashboard that returns more customized insights from the insights generated by app.
The app is a facebook connect website that users visit and view a list of products. They can post to facebook about that particular product by sharing a custom story that incorporates that product on their timeline.
When I go to the insights for my app, it does a great job of showing me all social impressions for all custom stories that were generated on my site.
I'd like to narrow that down even more for specific products.
My plan is to record the object ids that are generated by these actions and link them to a partucular product in my database.
I'd then like to create a new dashboard page that will allow me to login, request read_insights permission from me and then use that object_id:product mapping from my database to show how many social impressions where recorded for a given product's object_ids.
Is this possible? I've read alot about it but still haven't found the most elegant way to get a segmented report of social impressions per type of content that was posted.
Thanks for your time.
The implementation all depends on which platform you want your app to run on.
The first major component is you must have a Facebook developers account which is easy to signup for. Just go to developers.facebook.com and register. Takes like 2 mins. After that you will need to create your first app and add the correct domain name where your app will be hosted and what platform it will run on. (iOS, Android, Web, ect.) Once that is finished you can make your app public so you can use the Facebook API in your code.
For the app creation itself. The first thing you need to do is import the correct API for your platform. Which you can find a walk through at https://developers.facebook.com/docs/. Once the API is imported you must build a Facebook object which contains your app id and possibly app secret. If you're using JavaScript you don't want to use the app secret because it will be visible to the public.
Now that you have your Facebook object you must require the app users to log in and grant permission to your app. You can add extended permissions to your log in process by adding a scope value to the log in button generated by Facebook. Here is an example.
<fb:login-button id="loginBtn" max_rows="1" scope="basic_info,read_insights,manage_pages" size="medium" show_faces="false" auto_logout_link="true"></fb:login-button>
After the user is logged in you can now query information from the users account using Facebook Api calls to Social Graph. Facebook also provides a tool to help you figure out what information you can query. https://developers.facebook.com/tools/explorer
Everything else you want to do with the app can be done by Facebook API calls. You just need to insure you grant the user the correct permissions before making the API calls.
API calls are a little different depending on which language syntax you are using but they all follow the same data model and return some array of responses which can be parsed using JSON or the standard array format. The Graph Explorer tool listed above will show you the output for your queries so you can handle them accordingly.
I hope this helps gets you started.
EDITED
Here's the implementation in JavaScript
function getMetric(){
// make the API call
FB.api(
"/{app-id}/insights/application_opengraph_story_impressions",
function (response) {
if (response && !response.error) {
/* handle the result */
}
}
);
}
Here's the reference now that Facebook docs are back up https://developers.facebook.com/docs/graph-api/reference/insights
application_opengraph_story_impressions will probably give you the total impression of all stories made by your app. I ran it against my Facebook app and it came back empty but I don't have any stories so it might work with your's. Also to note in the documentation there is an * by this metric and I could't find what that means.
I'm pretty sure that right now Facebook don't give developers ability to get insights about app custom stories.
Currently Facebook documentation has the following Graph APIs for Insights data:
/{page-id}/insights
/{app-id}/insights
/{domain-id}/insights
/{post-id}/insights (where this is a Page post)
So /{post-id}/insights won't work because custom story is actually user's post and others endpoints don't apply to your case.
As far as I know the only other option to access Insights is FQL. For that you'd use insights table in a manner similar to this:
SELECT ... FROM insights WHERE object_id = ... AND metric = ... AND end_time = ... AND period = ...
Now most likely this also won't work with your custom story posts (I don't have posts which I could try it on right now, so I can't tell) but at least it is not explicitly stated so in the documentation, so you should probably try it out.
UPDATE:
I wasn't able to get any insights data via FQL, although as far as I understand the following code should have gave me at least something (object id is for my page):
SELECT breakdown, end_time, event, metric, object_id, period, value FROM insights WHERE object_id = 224981264214413 and metric = 'page_fans' and period = period('lifetime') and end_time = 1395597892
But it results just in
{
"data": []
}
Facebook also has some pretty old bug report about similar topic: https://developers.facebook.com/x/bugs/508088155954330/ where they confirmed the issue, assigned it, and... did nothing to fix it for 6 months.
In case FQL doesn't work, my suggestion to you is - use your own analytics code to track the creation of custom stories and get the friend count of the users. It won't show you the real exposure of the posts but at least you will see some data on which types of custom stories where posted more often and what was the maximum potential friend count that could have seen them. By the way - to make charting easier, you could use Google Analytics events for that.
I have a page where user is asked only for the payment amount, then user will be redirected to another website where the payment will be processed, I want the amount to be set on the redirected page without using querystring,cokkie, etc..
I tried to use web service but here is my challange:
user enters amount on the website.
webservice is called and set the amount to ex:400$
then user is redirected without any query string to another website.
Now:
how this payment website will know that this user is the user entered 400$ on the redirecting page?
I can count on approaches more secure than this also.
thanks
I have made some research on net and asked my experienced friends, the answer is "impossible" this way.
Because redirected website somehow identify that user and there is no solution without querystrings or browser related components,
Here is my friend's advice and i am little bit satisfied, not totally :)
He calls this approach as ticketing,
First create a datetime.now integer, with that number add id and amount of money to be processed.
Then make a complex function to encrypt data. take square of every odd digit then divide to 7 etc.
then on the other website, decrypt data and check datetime if its within 5 minutes for example,
the link is valid.
You have to pass the data to the other website somehow.
Cookies wouldn't work due to domain restrictions.
Query string or form posts could work, but you don't want to use query strings.
Alternatively, if both sites share infrastructure, you could use that to share information - for example if they both have access to the same database, you could use that to share data (though you would still need to identify the specific user to both sites).
The way the service would have to work is to give back some token, probably a GUID, that the site will then look for in the querystring of an HTTP request, to identify the owner of that pre-populated data. You then tack that token onto your redirect, and the client makes a request that causes the payment site to go pull the pre-loaded data for that client.
You still have to use a query string, but now, the query string doesn't contain any human-consumable information; they can't identify their $400 amount in the query string and change it to a different amount of money. If they change the GUID at all, the request will most likely fail as that GUID won't exist in whatever datastore of pre-populated data exists behind the payment site.
Contact the website/web service/gateway. They will provide you the API which will define parameters and methods to accept payment amount. If you are the author of such service, provide mechanism to accept such parameters from your caller application. Communication should be secure, using SSL.
For example for payment gateway Paypal, check this for ideas:
Use of the PayPal payment system in ASP.NET
Have a look on wikipedia.
Shortly the answer is impossible this way, because somehow the redirect website should identify the user, all the ways are browser related or ip ( which can cause many issues later)
