A list of server IDs that are allowed to send messages to the application. It should contain at least one and no more than 100 sender IDs.
callback
function
The callback parameter looks like: (registrationId: string) => void
- registrationId
  string
  A registration ID assigned to the application by the GCM.

send

chrome.gcm.send(
  message: object,
  callback: function,
)

Sends a message according to its contents.

Parameters

message
object
A message to send to the other party via GCM.
- data
  object

- destinationId
  string
  The ID of the server to send the message to as assigned by Google API Console.
- messageId
  string
  The ID of the message. It must be unique for each message in scope of the applications. See the Cloud Messaging documentation for advice for picking and handling an ID.
- timeToLive
  number optional
  Time-to-live of the message in seconds. If it is not possible to send the message within that time, an onSendError event will be raised. A time-to-live of 0 indicates that the message should be sent immediately or fail if it's not possible. The maximum and a default value of time-to-live is 86400 seconds (1 day).
callback
function
The callback parameter looks like: (messageId: string) => void
- messageId
  string
  The ID of the message that the callback was issued for.

unregister
