Get Message Status¶
Backendless processes push notification delivery asynchronously. Even when the client app uses blocking/synchronous API, the server creates a push notification delivery task and adds to a queue. Server assigns an ID to the task and returns it to the client as messageId
. As a result, push notification delivery status is not available right away. To retrieve the status, the client application must make a separate API call documented below:
Blocking API
¶
Backendless.Messaging.getMessageStatus( String messageId );
Non-Blocking API¶
Backendless.Messaging.getMessageStatus( String messageId, AsyncCallback<MessageStatus> responder );
where:
messageId
- ID of the message assigned to the message and returned by the Message Publishing API request.
Return Value¶
Method returns an instance of com.backendless.messaging.MessageStatus
. The object contains the following properties:
messageId
- ID of the message for which the publishing status is retrieved.
status
- an instance of an enum type com.backendless.messaging.PublishStatusEnum
.
errorMessage
- contains detailed error message when status
is PublishStatusEnum.FAILED
.
