Sending Push via Postman using Firebase Messaging
<p>I'm trying to use <a href="https://www.getpostman.com/" rel="noreferrer">Postman</a> to send a single Push Notification using <code>Firebase</code> Cloud Messaging service.</p>

<p>This is a working <code>cURL</code> command for the same purposal, on which I'm using as a reference.</p>

<pre><code>curl -X POST --header "Authorization: key=&lt;API_ACCESS_KEY&gt;" --Header "Content-Type: application/json" https://fcm.googleapis.com/fcm/send -d "{\"to\":\"&lt;YOUR_DEVICE_ID_TOKEN&gt;\",\"notification\":{\"body\":\"Firebase\"} \"priority":\"10"}"
</code></pre>

<p>What I have done so far..</p>

<p>1 - Set the <strong>Headers</strong> appropriately</p>

<p><a href="https://i.stack.imgur.com/yH6f9.png" rel="noreferrer"><img src="https://i.stack.imgur.com/yH6f9.png" alt="enter image description here"></a></p>

<p>2- At <strong>Body</strong> , I'm using <code>raw</code></p>

<pre><code>{
    "to" : "&lt;YOUR_DEVICE_ID_TOKEN&gt;"
    , 

    "notification": {
    "body": "Firebase Cloud Message"
  }

  }
</code></pre>

<p>When executing, I'm getting back <code>401 - Unauthorized</code>.</p>

<p>What's missing to correctly send the push notification?</p>
