I have a php script that attempts to POST a post to a Facebook page via CURL, but fails with the error.
(#200) If posting to a group, requires app being installed in the group, and either publish_to_groups permission with user token, or both pages_read_engagement and pages_manage_posts permission with page token; If posting to a page, requires both pages_read_engagement and pages_manage_posts as an admin with sufficient administrative permission
The exact same POST works from Facebooks API Graph Explorer. The same page access token is used in both cases. I have checked the token in Facebook's token debugger and the permissions mentioned in the error are both present.
The code I'm using is:
$post_content = "message=".$message."&access_token=".$ae_page_access_token;
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v13.0/{page-ID}/feed');
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_content);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
Interestingly, I can post photos with captions to the page with the same access token from my php script without an error. The error only happens when using https://graph.facebook.com/v13.0/{page-ID}/feed -- the permissions just don't seem to work in this case. No idea why.
Can anyone suggest how to troubleshoot further or a possible cause? Any advice gratefully received
Well this is embarrassing. Misspelled parameter in a function call was the culprit. Works now.
Try this
$post_content = "message=".$message;
curl_setopt($ch, CURLOPT_URL, 'https://graph.facebook.com/v13.0/{page-ID}/feed?access_token=' . $ae_page_access_token);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_content);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
token place is in url like a get parameter https://developers.facebook.com/docs/facebook-login/guides/access-tokens#pagetokens

I am trying to use an API which says to use it in a custom application to set a custom referer. Here's the official text:
The API requires (if enabled) a token for read operations to be send
to allow request, otherwise "Missing 'key' parameter" message will be
returned.
The security module will use the referrer heading ("referer" in Java,
HTTP_REFERER in PHP) of the request to identify and filter the
authorized domains.
I can currently log in to the web interface by using a special URL provided which seems to set the session and then redirects to the main URL. If I try navigating to the main URL directly without first using the special URL, I get a 401 error, as expected (afterwards, I can just use the main URL)
The key given below the text above is something like: http://example.com/api/?key=secretkeyhere
While I can use the API using the GUI tool in my web browser as described above, I can't figure out how to connect to it programatically. I have tried using both curl in Linux as well as curl in PHP. Both have failed.
curl from terminal:
curl --header http://example.com/api/?key=secretkeyhere http://example.com/api/search?query=terms*
curl in PHP:
<?php
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'http://example.com/api/search?query=terms');
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_REFERER, 'http://example.com/api/?key=secretkeyhere');
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, true);
curl_setopt($ch, CURLOPT_AUTOREFERER, true);
$html = curl_exec($ch);
curl_close($ch);
echo "$html";
?>
I continue to get:
Unauthorized This server could not verify that you are authorized to
access the document requested. Either you supplied the wrong
credentials (e.g., bad password), or your browser doesn't understand
how to supply the credentials required.
Am I doing something wrong here? Is the API not set up correctly? I've read the man page for cURL and it seems like this is exactly what I should be doing.
I set up an app on linkedIn. Set up and tested code to return an access token. Which all worked fine. I tried to get basic profile data and it says I do not have proper access rights. I gave the app all basic permission other than write posts so I am at a loss for why nothing is being returned.
The error:{"serviceErrorCode":100,"message":"Not enough permissions to access: GET /me","status":403}
My code is below.THETOKENWOULDBEHERE in the live code is the token returned by the oauth process. If anyone has any insights it would be appreciated.
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, "https://api.linkedin.com/v2/me");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_HTTPHEADER, array('X-RestLi-Protocol-Version:2.0.0','x-li-format: json','Authorization: Bearer *THETOKENWOULDBEHERE*'));
$response = curl_exec($ch);
curl_close($ch);
print_r($response);
If you are using V2 and you did not taken permission to use r_basicprofile
then either apply for permission to use r_basicprofile to linkedin
or use r_liteprofile + r_emailaddress

I'm currently trying to get a list of skills from the Alexa Skill Management API using PHP. My access token currently works to get user profile info and I'm 99% sure I gave the correct scope for permission to my Skill Development Account.
// exchange the access token for list of skills
$c = curl_init('https://api.amazonalexa.com/v0/skills/');
curl_setopt($c, CURLOPT_HTTPHEADER, array('Authorization: ' . $access_token));
curl_setopt($c, CURLOPT_RETURNTRANSFER, true);
curl_setopt($c, CURLOPT_VERBOSE, 1);
$r = curl_exec($c);
curl_close($c);
var_dump($r);
The above code returns the error:
The requested method GET is not allowed for the URL /v0/skills/.
I'm sure I'm just making some silly mistake. Any help would be appreciated.
I have tried the same in POSTMAN but with POST instead of GET and looks fine (I got an Unauthorized error, which just because of token missing). It means the API you are trying to connect is not a GET method but post. So please try the request type as POST. Please see below the same API I have tried with POSTMAN
To make sure it is because of the problem with HTTP verb GET, I have reproduced the same error with GET. Please see below screenshot,
Please try add one line like below to make your request a POST,
curl_setopt($c, CURLOPT_POST, 1);
Previously I have been able to access the Facebook OAuth services through cURL in PHP. However, I am now getting a 2500 error (In this case An active access token must be used to query information about the current user.). I can access the information by using the URL straight through my web browser, however when I try to access it with cURL in PHP it doesnt work. I am using Facebook API v1.0, and the token is being generated with the Graph API Explorer.
What I have tried
I have tried creating a new access token, as well as tried using Facebook API v2.0 and the unversioned API. As I said above, I have tried using the exact same URLs in my browser, which works. I have also tried clearing cookies and trying again, as well as trying a whole different browser.
I have seen some of the other questions on SO which relate to this question but none of the answers work for me.
The code
The URL I am using is simply a call to the /me/home edge.
https://graph.facebook.com/v1.0/me/home/?since=1402913078&until=1402913213&access_token=<access token here>
Where <access token here> is the access token
The PHP cURL code looks like the following:
$url = "<the url here>";
$ch = curl_init();
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_URL, $url);
curl_setopt($ch, CURLOPT_HEADER, true);
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($ch);
// get the response here...
It turns out that the actual URL being requested by cURL was different to the one that should have been being requested (the GET parameters were missing). This was caused by another location in the code.
To verify that the URL that is being requested is the same as the one passed to cURL, use the following code:
$requested_url = curl_getinfo($ch, CURLINFO_EFFECTIVE_URL);
I've been banging my head against a wall for a few hours now - and it's probably something really obvious I've missed!
I'm trying to connect to a payment service provider (PSP) using CURL, post data and follow the post so the user actually ends up on the PSP's site.
Using the following:
$ch = curl_init();
curl_setopt($ch, CURLOPT_URL, 'https://psp.com/theirpage');
curl_setopt($ch, CURLOPT_REFERER, "http://mysite.com/mypage");
curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt($ch, CURLOPT_FOLLOWLOCATION, 1);
curl_setopt($ch, CURLOPT_POSTFIELDS,$params);
curl_setopt($ch, CURLOPT_POST, 1);
$result=curl_exec($ch);
curl_close($ch);
This successfully connects, verifies the data I've passed, but instead of redirecting the user to the PSP, it just loads the HTML on my site. Safe mode is off, and open_basedir is blank.
What am I doing wrong?
CURL would do an internal redirect and it wont have any effect on the user viewing your curl script. Keep in mind that the payment was made by your server NOT the users computer, hence expecting the session to work for the user is incorrect. cURL 'is the browser'.
If you just want a redirect after payment is made via cURL, you will have to do it via header() or by using some JS like window.location.
The curl request is being made from your server, and as such your server is receiving the response page. There's no way to initiate the request from the server and have the client receive the response. Either return the HTML to the user from your site (as you're doing), or make the request from the client's browser using Javascript. Hope that helps
