How to register a userId to Bluemix Push Notificat

Question

the REST API documentation for Bluemix Push Notification services states that the possible push notification targets are deviceIds, platforms, tagNames and userIds.

I don't understand how you register a userId for a device ? I don't see any REST service that seem to take a userId in its inputs...

Thanks for your help,

Answer 1

There is a deviceId that you can set from the REST API when using the POST devices call to register a device.

In the DeviceRegResponseModel is userId (string, optional): The user identifier for the the device registration

So essentially to set a userId you'll just want to add that to the json you send when registering a device through the REST API. So just modifying the example the REST API gives for the body:

{
  "deviceId": "TestDeviceId",
  "platform": "A",
  "token": "************",
  "userId": "John"
}

And then you can use the POST messages call with "userId": "John" in your target body to send that message to all devices registered with the userId "John".

Hope this helps.
