Allows to communicate with other users depending on what apps you and they have installed.
Here are some examples:
As I mentioned, it depends on the apps you have installed so give it a try and see what shows up for you :).
Use the built-in helper to check what apps and contacts work for you.
If you have WhatsApp installed you can use this action to send text messages directly by selecting the WhatsApp (vnd.com.whatsapp.profile) option with the App field's helper.
If you enter some text, Tasker will use its Keyboard to automatically input and send some text. It'll also give you the option to Back Out of the chat so that you can end up where you started before the message was sent.
Important Note: to use the Text option your device's screen needs to be on and unlocked so that the chat window can open, Tasker can input the needed text and send it.
