I want to schedule push notification 3 times a day one morning and evening and night so there are cron job available to can schedule the push notification every 8 hours and thanks
You can do this using Backendless Timers. See this for more information:
The way it works is you’d need to deploy Java code to our servers which would have the schedule you need. Backendless will run your code accordingly to the schedule and in there you will send out push notifications.
Hope this helps.
I forgot to mention that it is very easy to create timers using Backendless console. See this chapter in the doc for details (scroll to the Timers section):
