google-cloud-messaging Getting started with google-cloud-messaging Send downstream messages from the cloud

Example

Send a message using GCM HTTP connection server protocol:

  https://gcm-http.googleapis.com/gcm/send
  Content-Type:application/json
  Authorization:key=AIzaSyZ-1u...0GBYzPu7Udno5aA
  {
    "to": "/topics/foo-bar",
    "data": {
      "message": "This is a GCM Topic Message!",
     }
  }

To do this in Postman, you simply have to set the following (some details are as what is mentioned above):

1. Set request type to POST
2. In the Headers, set the following:
   • Content-Type = application/json
   • Authorization = < Your GCM Server Key >
3. Set the payload parameters in the Body (in this example, we used the raw option, see screenshot (2))
4. Send the request to https://gcm-http.googleapis.com/gcm/send

Notice that the request was a success with the message_id in the response.

_{PS: I'm keeping the sample Server Key visible so that others can still try it out even if they haven't created a Project yet. BUT, note that the Server Key must be always kept secret.}
