We need to send a notification when an alert is generated in OneClick through a WhatsApp message. According to the communities, this is not supported directly with CA. Is there anyone who has explored this through other means?
Correct. We do not have a direct integration with any SMS app.
A quick search does appear that WhatsApp can accept messages via shell script. Guessing it calls something else.
But you can setup Alarm Notifier to execute a script on an alarm.
You would have to edit the SetScript.
as WhatsApp uses a closed protcol, and there is no official API all libraries that exist seem to be more or less hacks using an unofficial API and "emulating" official WhatsApp clients.
If absolutely needed, i would also go the way Matthew described, using the Alarm Notifiers. Have in mind that the API could change anytime, and your solution might not be working anymore from one day to the other.
If possible, i would opt in for a more open solution, with n official API like XMPP/Jabber or Slack.
For WhatsApp integration i found this service WhatsApp API - waboxapp.
