I have seen that there are many applications which send the message on WhatsApp without open it.

Here is the one of an app link https://play.google.com/store/apps/details?id=com.future.whatslol which sends the message from the background even when mobile is locked or screen turned off.

I am able to send an automatic message but it opens the WhatsApp. These apps which send the message from the background needs notification access permission.
