Issue Summary

Currently, the "Restrict Page" action in Automation for Confluence does not support the use of smart values such as "{{content.owner.accountId}}" or "{{content.author.accountId}}". This limitation hinders the ability to dynamically manage page permissions based on content attributes.

Supporting for smart values within the "Restrict Page" action allows for more flexible and automated permission management. By enabling smart values, users can easily set page restrictions according to the content owner's or author's account ID, streamlining the process and reducing manual intervention.

Workaround

If possible, try using Update restrictions API request.
