Hi
in my messaging before publish event handler i want to add a property in the header of the message.
how can i do that?
If you want to add the header through the SDK, you can use PublishOptions. Here is the sample code for Android:
Map<String, String> headers = new HashMap<>();
headers.put("headerName", "headerValue");
PublishOptions publishOptions = new PublishOptions();
publishOptions.setHeaders(headers);
Backendless.Messaging.publish((Object) "My message", publishOptions);

I want to add the header property in the “beforePublish” event handler.
im doing some calculations in the event and i want to pass that to the subscribed users
Sorry, my mistake.
You can add the header to the PublishOptions in your event handler too. The beforePublish method receives the PublishOptions, so you can use the same code above.

Hello,
This is how the PublishOptions should be structured:
Notice there is headers property, which should contain object containing headers/values.

Could you check the contents of Request Publish Options after the property is set and before the event handler is done? This can be done using the print block and then checking in the real-time logging window when the API is executed.
it does have it
headers: { Request_id: 'request', ToUser: 'AAFCD463-3BF0-B20C-FF3B-C47584300000', FromUser: 'AAFCD463-3BF0-B20C-FF3B-C47584300000', ggg: '33' }
Thanks. Do you use real-time messaging to subscribe to the channel to receive messages or retrieve them using the REST endpoint?
i use the JS SDK to subscribe to the channel

i can add the header property but i get this when i want to return a the “created” column.
is this normal?
converting it to string first was the solution.
