send POST request in PHP to pushbullet API 401 error - php

Question

I'm trying to send simple push notifications with pushbullet just through using the email and sending those to the linked account to avoid needing account data. (see reference here: https://docs.pushbullet.com/#pushes)
Therefore I'm using a non cURL-method in php that I (not only) found here:
How do I send a POST request with PHP?
Unfortunately I get back an error as following:
<br />
<b>Warning</b>: file_get_contents(https://api.pushbullet.com/v2/pushes): failed to open stream: HTTP request failed! HTTP/1.0 401 Unauthorized
in <b>/path/to/function.php</b> on line <b>42</b><br />
bool(false)
Option to use urls for file_get_contents is set to "on".
My code:
$pushdata = array(
"email" => $email,
"type" => "link",
"title" => "Demo Pushbullet Notification",
"body" => "You have new comment(s)!",
"url" => "http://demo.example.com/comments"
);
//Post without cURL
$options = array(
'http' => array(
'header' => "Content-type: application/x-www-form-urlencoded\r\n"."Authorization: Bearer <xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx>\r\n",
'method' => 'POST',
'content' => http_build_query($pushdata),
),
);
$context = stream_context_create($options);
$result = file_get_contents("https://api.pushbullet.com/v2/pushes", false, $context, -1, 40000);
var_dump($result);
EDIT: Altered the code to christopherhesse's response, still doesn't work. It also shouldn't require access-tokens as I understand that pushing. I understand it as pushing notification from neutral to an linked email. Maybe I'm wrong, but the access-token doesn't fix it.
EDIT(solved): An access-token IS needed to push notifications and as it doesn't work with this method, it does work with cURL.

Answer 1

You need to be using cURL for this so you can pass the API key as a header defined in the documentation: https://docs.pushbullet.com/#http.
<?php
$curl = curl_init('https://api.pushbullet.com/v2/pushes');
curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);
curl_setopt($curl, CURLOPT_POST, true);
curl_setopt($curl, CURLOPT_HTTPHEADER, ['Authorization: Bearer <your_access_token_here>']);
curl_setopt($curl, CURLOPT_POSTFIELDS, ["email" => $email, "type" => "link", "title" => "Demo Pushbullet Notification", "body" => "You have new comment(s)!", "url" => "http://demo.example.com/comments"]);
// UN-COMMENT TO BYPASS THE SSL VERIFICATION IF YOU DON'T HAVE THE CERT BUNDLE (NOT RECOMMENDED).
// curl_setopt($curl, CURLOPT_SSL_VERIFYPEER, false);
$response = curl_exec($curl);
print_r($response);
THIS CODE IS COMPLETELY OFF THE TOP OF MY HEAD AND HASN'T BEEN TESTED
I have broken the options up so you can see them easily but you can combine them into an array and pass them via curl_setoptarray($curl, []);

Answer 2

Sounds like you're missing the access token for your user account. You can find it on https://www.pushbullet.com/account . You should include it in a header like 'Authorization': 'Bearer ACCESS_TOKEN_HERE'.

Answer 3

I know this is an old post but I was having the same problems with sendgrid that uses the same Authorization: Bearer APIKEY method as your website.
I finally got it to work using raw php post using the following code
$url = "your url";
$post_data = 'yourdata';
// Set the headers
$options = array('http' =>
array(
'method' => 'POST',
'header' => "Authorization: Bearer APIKEY\r\n" . 'Content-Type: application/x-www-form-urlencoded',
'content' => $post_data
)
);
// Send the POST data
$ctx = stream_context_create($options);
$fp = fopen($url, 'rb', false, $ctx);
// Read the POST data
$result = json_decode(stream_get_contents($fp));
echo "done";
It seems like switching the order of the header and leaving out the \r\n at the end seemed to work. I spent like an hour on this trying different combinations so I thought I would post this for others.
Note if your using the sendgrid api make sure to set the 'Content-Type: application/json' and make sure your $post_data is in json
