Posting on user's timeline on the behalf of the user - facebook

I created and APP on the Facebook.
Now I am trying to post a comment on the user's timeline using the Graph API but I cannot undestand what I need to do.
I already authorized the Application (I authorized this permissions: 'user_status,publish_stream,user_photos,email').
If I look on my profile -> privacy I can see that the APP can:
This app can: Post on your behalf
This app may post on your behalf, including status updates, photos and more.
Last data access:
Basic InformationToday
See details · Learn more
Posts on your behalf:
Who can see posts this app makes for you on your Facebook timeline?
Public
Notifications:
When to notify you?
The app sends you a notification
So this part seems OK.
On my application I do the following to try to post somenthing on my timeline (I need to post it when I am off line).
1) GET : https://graph.facebook.com/oauth/access_token?client_id=APPID&client_secret=*APP_SECRET*&grant_type=client_credentials
RESPONSE:
access_token = 422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk
2) GET: https://graph.facebook.com/search?q=myemail&type=user
RESPONSE:
_"error":_{
______"message":_"A_user_access_token_is_required_to_request_this_resource_",
______"type":_"OAuthException",
______"code":_102
___}
But reading the documentation (https://developers.facebook.com/docs/reference/api/#searching) it seems that this request does not need any kind of access token.
I also tried to add the access token, but the result is still the same.
3) I know my facebookid so I tried to use it directly:
POST: https://graph.facebook.com/100001139132403/feed
ARGUMENT:
access_token=422828347771671|UdQELQIf0N7krF4JUo7VwtPLTkk,
message=Hello
RESPONSE:
"error": {
"message": "(#200) This API call requires a valid app_id.",
"type": "OAuthException",
"code": 200
}
}
So I tried to add client_id=APPID and app_id=APPID, I tried to put one, the other and also both arguments as GET or POST but nothing changed.
I checked the APPId ad it is correct.
Do someone have any idea?
Thank you!

You cant simply generate a user access_token by querying to a URL. What you did gives the App access token and as the error say, you are trying to do something, that needs user access_token.
Refer and implement this : https://developers.facebook.com/docs/howtos/login/server-side-login/
And use that access_token for the rest of the processes.

Post to Instagram via Facebook Graph API - unable to get the correct ig-user-id permission

I need to create a Meta application that posts scheduled content on the Instagram page of the company. The app is now in dev mode, and used through the Graph API and cURL.
After getting an Instagram user token on the Graph Explorer with all the required permissions (email, pages_show_list, ads_management, business_management, instagram_basic, instagram_content_publish, publish_to_groups, pages_read_engagement, pages_manage_posts, public_profile) and getting the ig-user-id through the GET /v13.0/me?fields=id,name API call, i make the container generation call, as described in the docs:
curl -i -X POST https://graph.facebook.com/{{ig-user-id}}/media?
image_url=https://{{image-url}}&caption={{text}}&access_token={{token}}
To which I get as a response:
Unsupported post request. Object with ID '{{ig-user-id}}' does not exist, cannot be
loaded due to missing permissions, or does not support this operation.
I tried to generate a Page token in spite of an User token, to use the Page ID in spite of the Used scoped app ID provided by the Graph API but the result has always been the same. One thing I noticed is, trying to get the IG user ID as described on the getting started page, point 5, to my request:
curl -i -X GET "https://graph.facebook.com/v13.0/{{page-id}}?
fields=instagram_business_account&access_token={{token}}"
The response is just {"id":"{{page-id}}"} in spite of the expected
{
"instagram_business_account": {
"id": "17841405822304914" // Connected IG User ID
},
"id": "134895793791914" // Facebook Page ID
}
So it appears it might be a permissions issue. Now, on the Business Settings for the business the app is related:
I'm listed under Users -> People as Administrator and Developer
I'm listed under Account -> Instagram Account -> People with all the permissions (Content, Community Activity, etc.) granted but messages (Impossible to assign - Available only on Instagram)
I'm listed onder Account -> Apps -> {{App Name}} -> People twice with all permissions granted.
Could anyone help me solve the issue? Thanks in advance.

Permission issue when publish comment with Facebook Graph API v2.12

I am testing the facebook graph API comments
https://developers.facebook.com/docs/graph-api/reference/v2.12/object/comments
I checked my permission for the access token it contains the permission, which required by API. see the screenshot
I test my object-id (1797963943566411_1975256375837166) which is correct see me screenshot
Change the request method to POST and adding post data {"message": "haha"}
I get the error message shows:
"(#3) Publishing comments through the API is only available for page access tokens" see my screenshot
As you can see the first step checking, I have all the permission that the
API required.
Can any one see any sort of error in this process?
Try another way still not work.
I have a user who post a photo on his own facebook page.
I logged in with this user and give this user all permissions see the screenshot
enter image description here
call /me/accounts to get page access token
enter image description here
copy the page access token into the Graph API Explorer's access token field
call
GET: 1797963943566411_1975256375837166/likes
is working fine
But call POST: 1797963943566411_1975256375837166/likes
Get error response:
{
"error": {
"message": "(#200) Permissions error",
"type": "OAuthException",
"code": 200,
"fbtrace_id": "GtEaBfyXrUD"
}
}
The reason is Facebook changed the API behaviour. We are no longer to use api to like any POST on our time line. API can only like or comments on facebook page. Sad face !!!!

How to display "from" fields in comments via Facebook Graph API

I would like to find the id (app-scoped) for someone who has posted a comment on a public page.
For example, I get a list of recent posts/comments on the NY Times page via:
v2.11/nytimes/feed?fields=comments.limit(10){message,created_time,from},name,message,from&limit=2
The data returned looks like this:
"comments": {
"data": [
{
"message": "Wouldn’t know. Not paying $13/mo for this.",
"created_time": "2017-12-10T05:57:18+0000",
"id": "10151412260164999_10151414049324999"
}
],
There is no from field. The same is also true if I attempt to view the comment directly using it's id with
v2.11/10151412260164999_10151414049324999?fields=from,message,created_time
I have tried using the Facebook Graph API Explorer, using both my User Token, as well as an App Token.
Since v2.11 of the Graph API, you need a Page Token to get user data of comments: https://developers.facebook.com/docs/graph-api/changelog/version2.11#gapi-90
User information will not be included in GET responses for any objects owned by (on) a Page unless the request is made with a Page access token. This affects all nodes and edges that return data for objects owned by a Page.
In other words: You can only get user information if you manage the Page.
Edit: Since the latests update in the Graph API, you have to get the App reviewed and you must go through Business Verification or Individual Verification. (thanx #Guiman04)
Please check whether you are using the accessToken for the page you are trying to get data from, i had same issue, and was resolved by using the correct accessToken for the page.

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?
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 .

Retrieving facebook user wall posts through graph API

I'm currently working on a facebook app which captures wall posts for a specified user, page or group, after a user has authorized the app I quote the access_token that is returned to call the method
https://graph.facebook.com//feed?access_token=
this works fine for pages and groups as we only need a valid token, however for users the results are different depending on the relationship between the user who authorized the app the user whose posts are being captured.
For example if there is no relationship between the two users some posts are not returned even though they are public and displayed when you view the profile of the user, however if they are friends more posts are returned.
Can someone please explain this behaviour? And is it possible to obtain all posts using this method?
Yes, per the permissions listed at https://developers.facebook.com/docs/reference/api/permissions the results of the call are different depending upon the relationship.
However when things are public and you use an access token that doesn't belong to the user, then no results are returned. I cannot remember a time when this wasn't this way. For some odd reason (by design or omission on Facebook's part) using the graph API to get at public posts using a user access token just doesn't want to work.
For example, You can see some public items here
http://www.facebook.com/zuck
http://graph.facebook.com/zuck
However, you cannot seem to get any feed from here without an access token
https://graph.facebook.com/zuck/feed
{
"error": {
"message": "An access token is required to request this resource.",
"type": "OAuthException"
}
}
Let's try adding an user access token that does not belong to zuck or a friend of zuck. https://graph.facebook.com/zuck/feed?access_token={UserAccessToken}
And here's what we get:
{
"data": [
]
}
What about an app access token? Let's try
https://graph.facebook.com/zuck/feed?access_token={AppAccessToken}
{
"error": {
"message": "Invalid OAuth access token signature.",
"type": "OAuthException"
}
}
So as you can see, it's difficult to get things via the graph that are not in alignment with your access token.
I manage to get most of the feeds from user's wall post. Although this is a old post, I hope someone can manage to get what they want from my answer.
Before getting the access token(to get the feeds), you need to add multiple correct Read Permissions "keys".
For example, you will have to add "read_stream", and "user_status" (which I found that these are the most important permission "key" to generate the correct access token, to retrieve one's so-called "public" feeds).
You can add more into generating the access token, in either you want the permission to GET, or POST, or BOTH.
Source is here: https://developers.facebook.com/docs/howtos/ios-6/#nativeauthdialog
One thing that I found is, the way to get the feeds result from user's "Home/About" page and Facebook Page (which is created for people to like (not add friends)) are different. The key is mentioned above, "read_stream", and "user_status". So it's better that you add both of the permissions in order to generate the access token to get everything in feeds.
Graph API doesn't return posts to the App if is not authorized to read user feed, even if posts are public.
Source: https://developers.facebook.com/bugs/290004301178437/
According to the latest api ,
FB.api("/me/feed","get",function(response) {//callback})
should do and also work well .
It is working now but facebook may change it in future.
