HTTP Post attributes from parent

[xsign]

Got it.... {$accountName}

[xsign]

Hello,
I have created a workflow that has an action to send HTTP Request to slack webhook, and I am wondering if it is possible to use in payload field values from parent.

The scenario:
- Opportunity has been closed as won
- Send to slack message: "Account name" - "Opportunity name" - has been won.

The opportunity has a standard setup, default as in espo, that it is possible to assign the opportunity with an account - same field.

Any way to get the "Account name" ? I can get the Opportunity name easily via {$name}.

Thank you!
