Facebook Open Graph API Examples - How to get the access token? - facebook

Facebook has some great-looking examples of Open Graph requests here:
https://developers.facebook.com/docs/reference/api/examples/
The problem is that since I don't have an access token, most of the examples just return
{
"error": {
"message": "An active access token must be used to query information about the current user.",
"type": "OAuthException",
"code": 2500
}
}
I understand access tokens, but how do I get the token so that I can experiment with these example requests?

As long as you only want to test...
Use the Graph API Explorer to generate a token with the permissions you want.
Don't hesitate to select all of them.
Then, just copy/paste the token at the end of each graph.facebook.com URL. For instance:
https://graph.facebook.com/v1.0/me/friends?access_token=<ACCESS_TOKEN>
The day you want to get the access taken for an app...

Instagram Graph API unusual error during GET request for insights

I am trying to extract instagram insights data to further analyze it locally and store it. For that I generated a system user access_token with the required permissions. Now I am trying to perform a GET request just as described in this documentation: https://developers.facebook.com/docs/instagram-api/reference/ig-user/insights
For that my call URL looks like this:
https://graph.facebook.com/v15.0/{instagram-id}/insights?metric=impressions,reach,profile_views&period=day&access_token={system_user_token}
This gives following response:
{
"error": {
"message": "(#100) The value must be a valid insights metric",
"type": "OAuthException",
"code": 100,
"fbtrace_id": xxx }
}
Thinking maybe this is due to my system user token not beeing elegible for this call I tried the Graph API explorer in the browser and a generated access token with the needed permissions. I am not quite sure where to go from here. Thank you for your help
I tried different access_tokens generated in the business manager and also generated in the meta for developers website. I tried to use a variety of different metrics described in the documentation. All gave the same output as described above. I also tried different api versions (15.0 and 16.0)

Viewing graph api via url not showing data

So I have been watching some tutorials about the facebook graph API, and one of the things in the video is to simply navigate to http://graph.facebook.com/youtube
and it should display a json response of their facebook likes etc. This is said to work without an access token?
But this doesn't seem to work, i get the following response -
{
"error": {
"message": "An access token is required to request this resource.",
"type": "OAuthException",
"code": 104,
"fbtrace_id": "DoY144sSuti"
}
}
Has something changed that you will need to always need an access token just to see peoples data, eg how many likes a page has?

Yes. Since API v2.0, all API calls (with the profile picture redirect being the exception) need to use an access token.
Public data about public pages can be accessed using an app access token; if the page is not public it needs a user access token for a user that can see the page, or a page access token. (More about the different types of token here: https://developers.facebook.com/docs/facebook-login/access-tokens)
This is said to work without an access token?
Then that tutorial is simply outdated.
Yes you will need the access token in order to view that Jason data in URL .
try this Instead :
https://graph.facebook.com/page-id/posts?access_token={your-access- token}
You will be able to see the posts now.Hope this would help you .

How to get the result in Facebook Graph Api Explorer.? Getting error message (#15) This method must be called with an app access_token

I was Unable to get the search result in Facebook Graph Api Explorer For Topic search API. I am getting the following error. I also have the access token included.
{
"error": {
"message": "(#15) This method must be called with an app access_token.",
"type": "OAuthException",
"code": 15,
"fbtrace_id": "CJiZqVSATXu"
}
}
Well, the error message actually contains the problem. You're not using an App Access Token, but seemingly an User Access Token (from the Access Token structure in your screenshot).
You must select an app of yours in the upper right Applications dropdown, and then select Get App Token in the dropdown below.
Still, that will probably not help much in this case. Are you aware that only whitelisted apps can use the Topic Search API?
See

Facebook Open Graph event search

On Graph API Explorer I can do this search: search?q=Barcelona&type=event
But when I try the same with my app access token I get this error:
{
"error": {
"message": "(#200) Must have a valid access_token to access this endpoint",
"type": "OAuthException",
"code": 200
}
}
The other searches work well.
UPDATE 2017-11-27:
As Facebook doesn't allow an event search based on location anymore, I'd recommend to use https://github.com/tobilg/facebook-events-by-location-core
Original answer:
Please refer to https://developers.facebook.com/docs/reference/api/search/#access_tokens
There, it's stated that all searches except for pages and places require an user access token.

How to handle OAuthAccessTokenException in facebook api searches

I'm using Facebook API for searching. For example if I want to search for 'Conti' i get thsi url: https://graph.facebook.com/search?q=%22Conti%22&type=post
In this particular case, and others, instead of getting the list of results, I get this error:
{
"error": {
"type": "OAuthAccessTokenException",
"message": "An access token is required to request this resource."
}
}
why is this? should i get a token in order to the get the results?
UPDATE
Do I need to register an app?
You need to get the access token first, have a look at this tutorial:
