I'm making an application in angular 4. I get posts from a group in my app and I want people to comment on those posts. Problem is, you need a page access token but the api return an empty array!
https://graph.facebook.com/me/accounts?access_token={user_access_token}
I searched for days and looked through all the questions on stack but didn't find anything.
Keep in mind, it is for facebook workplace so the graph explorer doesn't work for this problem!
You have to give impersonate account permissions to your Workplace integration.
Then, you have to impersonate the account:
https://graph.facebook.com/{userId}?fields=impersonate_token
once you have the user token, you can use it to comment a post on behalf of the user. It is a POST call
https://graph.facebook.com/{postId}/comments
with in the payload
{
'message':'test'
}

When I call the api:
graph.facebook.com/userid?fields=business_discovery.username(name){followers_count,media_count}
in Graph API explore, I got an invalid parameter error:
(#100) Tried accessing nonexisting field (business_discovery) on node type (User)
Could anyone please explain to me what I miss in the API url?
Thanks
This only works for Instagram Business Accounts, but you seem to be using it with a normal user id.
As https://developers.facebook.com/docs/instagram-api/reference/user/business_discovery says,
Instagram Platform API account IDs will not work with the new Instagram Graph API. Please use the Page node to determine the correct Instagram Business Account ID associated with the Facebook page.
You can not use this for other types of Instagram accounts, only for business accounts.
In my case the problem was that the instagram account was not connected to the page when the access-token was issue i.e. I added the instagram account after connecting the app.
So what worked for me was to remove the app, make sure that the instagram account is connected to the page the connect the app. Now the access token works.
I am hitting a wall while developing seamless integration of a Facebook page with my bot.
Essentially I want to achieve same integration than Chatfuel or Manychat have, where being logged in with your Facebook account lets you to just choose what page you are connecting to them and you are good to go.
The problem I am facing is generating the proper token in order to bind the selected page to my app (bot). As per Facebook documentation:
When you create a subscribed_apps edge, the page-id you use in endpoint must match the page ID of the page access token used in the API call. The app that the access token is for is installed for the page.
Given the call has no other parameter than the access token, this access token has to be enough for Facebook to:
Authorize the action on the page.
Identify what app is being subscribed to the page.
This is confirmed while using the Facebook Graph API Explorer, where one selects the page and the app to bind and a proper access token is generated:
This token properly works using cURL in the terminal:
$ curl -X POST 'https://graph.facebook.com/v3.0/<MY_APP_ID_HERE>/subscribed_apps?access_token=<TOKEN_PASTED_FROM_GRAPH_API_EXPLORER>'
{"success":true}
With the Facebook Access token debugger (info icon on the left of the access token, then open in Access token tool), it is confirmed that the token knows about both the page and the app that have to be connected.
The question is, how are these page-app related token programmatically produced? I can't seem to find the proper API call in Facebook documentation and it is by all means possible, as Chatfuel and Manychat are doing this.
Thanks in advance for your support Lars Schwarz and community!
Adding some detail to Alex's answer, for it to be more complete.
When subscribing an app to a page, Facebook needs to:
Know what app you are talking about.
Know what page you are talking about.
Know that you have permissions on that page to subscribe an app.
How does Facebook know it all?
1 comes from the fact that Facebook login happens in the context of a page, actually, the Javascript code for Facebook contains your appId:
js.src = 'https://connect.facebook.net/en_US/sdk.js#xfbml=1&version=v3.0&appId=<YOUR_APP_ID_IS_HERE>&autoLogAppEvents=1';
2 Comes from the page_id in the URL used to subscribe apps to pages:
https://graph.facebook.com/v3.0/YOUR_APP_ID_HERE/subscribed_apps?access_token=YOUR_ACCESS_TOKEN_HERE
3 Comes from the access token, obtained in the context of an APP through Facebook login, that is passed as parameter in the URL used to subscribe apps to pages:
https://graph.facebook.com/v3.0/YOUR_APP_ID_HERE/subscribed_apps?access_token=YOUR_ACCESS_TOKEN_HERE
To do this, you need to put FB Login on your site/customer portal and request pages_messaging and manage_pages permissions. The person that logs in must be a Page Admin.
Once your app has been granted that permission for the page, you can generate a page access token as described here:
https://developers.facebook.com/docs/pages/access-tokens
All mutual friends request made from my app server (node) (also tried the Facebook API explorer) suddenly started returning an empty array for the data field. I confirmed and validated my access token and appsecret_proof on the API explorer. Do you know what has changed or what the request below is missing?
Note: both users use the app and have granted user_friends permission.
I am using v2.12
request
{
url: 'https://graph.facebook.com/v2.12/{user-facebookid}?fields=context.fields(all_mutual_friends.limit(5000))',
qs: {access_token: 'XXXXX'
,
appsecret_proof: crypto.createHmac('sha256', clientSecret).update(accessToken).digest('hex')
}
Yep. Facebook has taken down the Graph API for page access tokens. The only way to retrieve data (or was a week or so ago), was a temporary user token that lasts about 2 hours. It's totally broken my band's schedule page. I've been through every avenue and even spoke with a facebook ad team employee on the phone that was aware of it. She seemed to empathize but had no solution for me. I would count on it being down for a while.
I have finally figured out a work around for this. On your fb application, you have to disable the secret key requirement. This can be found under the advance settings of your fb application console. It's called "
Require App Secret".
Once you generate a fb PAGE access token, you get a fb page token, and then extend it.
here is the token debugger:
https://developers.facebook.com/tools/explorer/
You can extend the access token programmatically as explained here:
https://developers.facebook.com/docs/facebook-login/access-tokens/expiration-and-extension
AND
https://developers.facebook.com/docs/facebook-login/access-tokens/#pagetokens
There is also an extend tool in the access token debugger.
I have an application, that runs on server. On that server is background task, that will post status update on few social networks (Facebook, Twitter, G+). It must be completely server-side.
In Twitter API I'm able to use OAuth header to authorize API request. OAuth HTTP header uses consumer key, consumer secret, access token and access token secret to create the header. With this I'm able to post/update/delete tweets with no user interaction.
How can I do this for Facebook? I found a solution to obtain a long-lived access_token (2 months), but we don't want to regenerate access_token every 60 days. We want to use it for manage our Facebook page - post status updates, but completely server-side.
Am I able to do this for Facebook? Thanks for answers.
PS: I searched stackoverflow hundred-times but with no solution for my problem.
Thanks.
It is not possible for User Access Tokens (they can only be extended to 60 days and need to be refreshed by the user after that), but for posting to a Page you should use a Page Token anyway. An Extended Page Token is valid forever.
Here are some Links to help you get that Extended Page Token:
https://developers.facebook.com/docs/facebook-login/access-tokens/
http://www.devils-heaven.com/facebook-access-tokens/
http://www.devils-heaven.com/extended-page-access-tokens-curl/
A Page Token will post "as Page" btw, but that´s probably what you want. And auto-posting on user profiles is not really allowed anyway, every message has to be 100% user generated and every posting should get authorized by the user.
Pay attention to Access Tokens Expiration & Extentions.
The Page Access Token could be a good solution to only server side calls for testing and data analysis purposes.
Take your User Access Token from Graph API Tool
Extend your User Access Token
Call https://graph.facebook.com/v2.11/me/accounts with your user access token extended
*all calls are GET and this procedure does not use APP Access Token.
I'm using the Facebook php sdk to try to get posts of a users wall.
When I use the following code I only get some reaction on events and some mentions, but but not the messages, photos's etc. I actually posted on my wall?
What can be the problem?
$result = $facebook->api('/me/feed/',array('access_token' => $facebook->access_token,'limit'=>100));
How are you authenticating and what permissions are you asking for in your access_token? If you aren't authenticating your user, you'll be limited to public posts only. You also need to make sure you request read_stream permission when you authenticate your user.
