Automatically send sms upon different events

I am looking for an easy way to implement automatic sms on different events. Like:

  1. Leave request received (sms to leave approver)
  2. Leave accepted/rejected (sms to employee)
  3. PO sent (sms to vendor with item name and quantity)
  4. Payment received (to client/customer)
  5. Greetings/thank you text to customer upon creation of a contract, etc.
    and some other similar/different events.

I looked upon the issue over the forum but could not find any exact solution.

you can set up notifications for different events.

See this SMS notification settings for sending sms about PO (for example.)

Another one _: sms to supplier

For leave application:

You can write small scripts and achieve results.

Hope this helps.
