Forbidden error 403 in Unification Engine API while sending message - php

Question

I am using #unificationengine API to send message on facebook.
Details I have given while registering my APP on facebook:
site url : http://localhost:3000
Email adress and other required details
In unificationengine API I have used all the curls mentioned in their documentation step by step as follows:
1. Created user using API key and Secret
2. Added connection
3. test connection
4. Refresh connection
5. Send message
All 4 gave 200 success code but send message gives 403 fobidden error.
The curl I am using for this is as below:
$post_msg = json_encode(
array(
'message' =>
array(
'receivers' =>
array(
array(
'name' => 'Me',
'address' => 'https://graph.facebook.com/v2.5/me/feed',
'Connector' => 'facebook'
),
),
'sender' =>
array('address' => ''),
'subject' => 'Hello',
'parts' =>
array(
array(
'id' => '1',
'contentType' => 'text/plain',
'data' => 'Hi welcome to UE',
'size' => 100,
'type' => 'body',
'sort' => 0
),
),
),
)
);
$ch = curl_init('https://apiv2.unificationengine.com/v2/message/send');
curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, 0);
curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, 0);
curl_setopt($ch, CURLOPT_VERBOSE, true);
curl_setopt($ch, CURLOPT_USERPWD,'3f43c37b-a066-4cc4-a3be-33faf72d6a21:2722fc72d-5d347-4a3a-a82b-0c1ss51aafb4');
curl_setopt($ch, CURLOPT_HTTPAUTH, CURLAUTH_BASIC);
curl_setopt($ch, CURLOPT_POSTFIELDS, $post_msg);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
// execute!
$response = curl_exec($ch);
// close the connection, release resources used
curl_close($ch);
// do anything you want with your response
var_dump($response);
return ['label' =>$response];
I am trying to figure this. But no success.
Again I like to mention that I am using this on localhost, could that be the reason for forbidden error? If so then facebook graph api from which we get access token should also give such error.
Earlier I have posted this question, here also I didn't find right solution. I added Curl options that is mentioned in comment of my question there but it didn't changed the things.
Any help would be highly appreciated.
Error Message:
{\"Status\":{\"facebook\":{\"status\":403,\"info\":\"Forbidden:
\"}},\"URIs\":[]}
UPDATE
Below is the json I get when I run me/permissions in facebook graph API explorer:
{
"data": [
{
"permission": "user_birthday",
"status": "granted"
},
{
"permission": "user_about_me",
"status": "granted"
},
{
"permission": "user_status",
"status": "granted"
},
{
"permission": "user_posts",
"status": "granted"
},
{
"permission": "email",
"status": "granted"
},
{
"permission": "manage_pages",
"status": "granted"
},
{
"permission": "publish_actions",
"status": "granted"
},
{
"permission": "public_profile",
"status": "granted"
}
]
}

Answer 1

I have resolved this problem:
public function facebookSharing($access_token) {
$app = new UEApp(env('UNIFICATION_APP_KEY'), env('UNIFICATION_APP_SECRATE'));
$user = new UEUser('unification_userkey', 'unification_usersecret');
$connection = $user->add_connection('FACEBOOK', "facebook", $access_token);
$options = array(
"receivers" => array(
array(
"name"=> "Me"
)
),
"message"=>array(
"subject"=>'testing',
"body"=> 'description',
"image"=> 'use any image url',
"link"=>array(
"uri"=> 'any web site url',
"description"=> "",
"title"=>"Title"
)
)
);
$uris = $connection->send_message($options);
}
Please use your keys like
facebook accesstoken
UNIFICATION_APP_KEY (its your unification keys)
UNIFICATION_APP_SECRATE (its your unification keys)
If this will not work then please let me know.

Answer 2

Can you please confirm if the "Connector" name that you have given is correct?
While I tried your sample code that you provided, I could sent the message to facebook via UE.
Can you please provide the exact error message that is returned while you execute the command?
