To add Check if placeholder exists on Page you will need the following:
Requirements
Confluence Template Created (use the same template used to create) - if not created, follow this guide
Confluence Page Customfield
Go to a transition in Workflow Edit and Click on “Add Condition”
and then Choose Check if placeholder exists on page
Filling the form
1. Choose a template
Click on Confluence Template
A list of all confluence templates will pop up
Choose a template to be used in this action
2. Choose a Page Customfield
Choose a page customfield where the value reflects the Confluence page intended to be checked
3. Choose the checked placeholders
Click on toggle button next to each placeholder that should be checked if exists, for e.g.
This condition would fail at run-time if the page still has any of (Admin & CurrentDate) placeholders
This condition would pass at run-time if the page has none of (Admin & CurrentDate) placeholders
5. Run as User
Leaving this field empty would run this action as the current user (Logged in User), and you may specify to run the action as Global Confluence Admin or as user from user picker search
