We're using the Incoming Webhook connector to send alerts to a Teams channel. I do a similar thing for Slack, where I can change the identity (i.e. name and avatar) of the "person" posting the message, based on attributes of the JSON payload. However, I've had trouble finding full documentation of the available payload attributes used for this connector, and the examples I've seen are very basic, using only payload attributes that define the title and message of the resulting card.
So is there an authoritative document out there that defines all the available payload attributes for the Incoming Webhook connector? And do the available attributes allow for customizing the name and avatar/icon of the simulated user who is posting?
