Soundcloud API /resolve method 404 error - javascript

Simple dimple one here- trying to use Soundcloud's resolve method to retrieve a JSON feed of track data for a private set.
http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/myUser/private-set
resolve returns a 401 unauthorized error, as it should
http://api.soundcloud.com/resolve.json?url=http://soundcloud.com/myUser/private-set&client_id=myClientID
resolve returns a '404' not found error. it should be 301 redirecting to the authorized JSON feed for the track, such as http://api.soundcloud.com/tracks/49931.json in the doc's example
I've created an App
I'm using the App's Client ID
I've enabled App access in the Set's edit menu
I'm formatting it as per the API docs
Am I missing something here?

So after some testing I've confirmed that the issue is related to the fact that you're trying to request a private set. Because the set is private, you would need to first go through SoundCloud's OAuth 2 authentication process before being able to access the set.

Try resolving the set url with the url found in the share dialog of your set. This url contains a secret token that can be used to access a private set without logging in.
Not sure how far this'll get you if the tracks in the set are also private, though. And like bbone mentioned, you'll be exposing this secret token, which may or may not be a problem.

401 Unauthorized API

I've stumbled upon a problem whilst working on a weather app. I have 401 error popping up every time i'm trying to fetch API from openweathermap.com. I've tried everything so far to fix this problem like waiting some days until my API key would work for me. I also tried to create a new API key and use it but failed at it again. Finally i tried to create another account on openweathermap.com but still have this error. Can anyone help me to find out what is the problem?
P.S. i used a valid API for checking a basic weather info that is available for free subscribtion.

Your API Key is provided as a value to query parameter: appid is wrapped in {}. Remove those braces and perform the request again.
Very often, you will find the usage of {} in the documents, they represent placeholders in a string and are not meant to be part of the final string.
Weathermap Docs: How to make an API Call?
Also, please, make sure that you DO NOT share any essential API Keys in a public forum.
{} should be removed inside the url. It should be
let api = `https://api/openweathermap.org/data/2.5/weather?q=${city}&appid=e2850163218373000f889c28107ac0cf`

Get an access token without being connected to facebook

I need to retrieve a facebook page's list of posts (feed) using their javascript SDK, just like they explain in their docs: https://developers.facebook.com/docs/graph-api/reference/v2.4/page/feed
/* make the API call */
FB.api(
"/{page-id}/posts",
function (response) {
if (response && !response.error) {
/* handle the result */
}
}
);
I need it to be my website's "news section", so users should see it even if they are not connected to facebook.
The problem
Cool, but there is a problem... It returns: An access token is required to request this resource.
Holy cow... I'd like to get some access token for you #facebook, but my app doesn't make use of your authentication tools/plugins.
ANYWAY, I tried with FB.getLoginStatus(); but doesn't work, because the only way it can return an access_token is if the user is actually connected to the application. My users may not even be logged to facebook!
So, ¿How can I get an access_token to be stored into a variable, and later be used to get /{my-page}/posts?
I've already payed a look to this SO question, but it doesn't solves my problem, simply because there are no such "generic tokens".
I've also read https://developers.facebook.com/docs/facebook-login/access-tokens/ and that also relies on tokens generated through facebook login methods... So, can't I display a list of fb page's posts in my website, without being connected into facebook, hence an application?
ADD: My app is build with angularJS, I'm not dealing with server-side code. I shall rely purely on javascript methods.
You could either use an page or an app access token, but as you'd be using them on the client-side, neither of them are an option.
See
https://developers.facebook.com/docs/facebook-login/access-tokens#apptokens
https://developers.facebook.com/docs/facebook-login/access-tokens#pagetokens
Note that because this request uses your app secret, it must never be made in client-side code or in an app binary that could be decompiled. It is important that your app secret is never shared with anyone. Therefore, this API call should only be made using server-side code.
I'd strongly recommend to build a simple server-side script (PHP for example) to proxy the request to the Graph API. You could then call this via AJAX for example and load the posts asynchronously (and alse get rid of the FB JS SDK!). There is NO way to handle this in a secure manner if you don't want to use FB Login for all of your users (which also doesn't make much sense IMHO).
I think it's straightforward :)
Since pages' posts are always public, it only needs a valid access token to retrieve page posts.
Quoting what you've written:
So, ¿How can I get an access_token to be stored into a variable, and later be used to get /{my-page}/posts?
You only require an access token.
My suggestion would be;
- Generate an access token for yourself (no extra permission needed)
- request page-id/posts
This way you don't require other users to be connected to facebook, you can simply requests page-id/posts to retrieve posts with access token you generated for yourself.
I hope it solves your problem :D
TIP: As long as posts are public, you only require a valid access token, it doesn't need to be user or page specific.

Get Page Access Token from FQL?

I'm having difficulty finding a way to get a page access_token from FQL.
http://developers.facebook.com/tools/explorer?method=GET&path=me%2Faccounts
- This is the graph call with the page access_tokens included. The trouble is that I need the access tokens for a multiquery call and would love to not have to make a separate call just for the access tokens then call the same info for my multiquery.
http://developers.facebook.com/docs/reference/fql/page_admin/
- This doesn't contain the access token, although it mentions contains the same data as the /user/accounts graph api call.
http://developers.facebook.com/docs/reference/fql/page/
- This also doesn't seem to include the page access token.
Has anyone had luck or found a way to get that token through FQL?
Thanks for your help!
It is possible!
SELECT access_token FROM page WHERE page_id={id}
It's not possible to get the access token from FQL, you can only do it via Graph API calls.
FQL is for queries from tables.
Graph API is for GET, POST and DELETE requests

Facebook Page has a fan or not

Im trying to use javascript to determine if a user is a fan of a page that i've created on my account.
I found the facebook graph api which looks like just what i want. However it appears for some functionality i need an access token.
Here it says I can just http get my /user_id/accounts page with the manage_pages permission and it will list the access token for each page.
But when i submit https://graph.facebook.com/myuserid/accounts&scope=manage_pages i get "OAuthException : Access token is required to request this resource."
I also tried from this answer, but then i get "An error occurred, please try later".
Any suggestions most welcome.
You will need an access token to retrieve any information that is not public on facebook.
You can read up on this page about authenticating a user. Once your user is authenticated you can retrieve the access token and use it in your future requests (for that user)..
eg:
https://graph.facebook.com/{YOUR_USER_ID}/accounts&access_token={YOUR_ACCESS_TOKEN}

Using Facebook Javascript SDK to get Graph Data

FIXED NOW! But I can't answer my own question yet. See my comment below. And thanks for helping.
I've searched and searched and read the docs and still can't figure this out.
I have a web page about an event. There's also a public Facebook "event" for my event. I'm trying to use the FB Javascript SDK to get the number of attendees for the Facebook event and add it to the number of people who've registered through the website.
I've created an app and I have an appID and secret string. I can get an access token from:
https://graph.facebook.com/oauth/access_token?client_id=XXXX&client_secret=XXXXX&grant_type=client_credentials
and I can then use that access token to get the attendees for a public event:
https://graph.facebook.com/331218348435/attending?access_token=XXXXXXXXX
That's all fine.
I'm now trying to do this same thing using the Javascript SDK.
I've loaded the SDK and done an init:
FB.init({
appId : 'XXXXXXXX',
status : true, // check login status
cookie : true, // enable cookies to allow the server to access the session
xfbml : true // parse XFBML
});
and I know the SDK is working because I can get an object with the data that doesn't need an access token:
FB.api( '/331218348435', function (response) { console.log ( response ) } );
but when I try to get the attendee data that needs the access token:
FB.api( '/331218348435/attending', function (response) { console.log ( response ) } );
I get an OAuthException: "An access token is required to request this resource."
All the tutorials and information I can find all refers to using the .login method, but I don't want a user to login, I want to login using my app ID without any user interaction.
I'd assumed that the API took the SDK's init request and granted me an access token when I called the .init method, the authentication being done against my website's address (the HTTP referrer - yes I have set my website URL in the Facebook app settings).
Any ideas what might be causing this to not work? How can I get the access token using the Javascript SDK without doing a .login? Am I missing a step? Is this even possible?
Thanks
Form what the rather circular documentations says, getting the attending feed requires a 'generic access_token`. In Facebook terms:
Any valid access_token
Any valid access token returned by our APIs. An access token may not be valid if, for example, it has expired. No special permissions are required. Occasionally, this is referred to as a generic access_token.
So this means that you can use any token you like to access the attending feed, as long as the event is public. The easiest access token to get seems to be an app token: http://developers.facebook.com/docs/authentication/#applogin. You can get this token using only your App ID and Secret, and no user interaction is required.
To summerise the link content: You can get an application access token by sending a GET request to
https://graph.facebook.com/oauth/access_token?client_id=YOUR_APP_ID&client_secret=YOUR_APP_SECRET&grant_type=client_credentials
You can then use that access_token to make the call for you attending list
FB.api('MyEvent/attending?access_token=ACCESS_TOKEN');
Oh. OK.
Well, for whatever reason, I went away and had my dinner and when I come back it's working fine.
When I updated the settings for my app Facebook said it might take a few minutes for the change to get around the servers. Turned out to take over an hour!
My code was fine.
Thanks for your help.
