MT30 automation message using custom webhook template

[MMTIT]

I wish to set up an MT30 to send a Google Chat message. The Automation builder allows one to send a webhook command that includes a box to enter a message. I created a webhook custom template because I did not see any reference to the automation message in the included Meraki template. I am unable to find a list of object names for the Meraki automation builder to pass the contents of the message box to Google Chat.

My current work-around is to create a custom webhook template and quote text in a text object:

{
"text": "my custom message"
}

This works but will be difficult for the next person to understand why text is the messages box of the Automation builder cannot be updated. There must be a better way.

I don't know the answer, but I bet it is contained in the developer documentation for webhooks.

I appreciate your time and energy to respond.

One would think https://developer.cisco.com/meraki/webhooks/ would provide a reference to the messages, but I had read this documentation before posting in the forum. I had also checked https://developer.cisco.com/meraki/webhooks/introduction/

I'm hoping someone who has real-world experience with the message box can answer.
