What are callback actions
You can choose to trigger an action after another action is finished by using callback. This allows you to execute an action whenever all background jobs of another action are done. This does not include background jobs of other triggered actions by the original action. This is mostly used for processing imported records from an import event.

You can check Enable callback action to open the callback settings. You will find the options:
Action: Select the action you want to execute as callback.
Assign: Assign values the selected action uses for its input variables.
Execute this action in foreground: Set the callback action to run in the foreground if it is currently set to background.
Go to Actions by clicking on the Actions icon in the Builder Bar.
Choose an action and open the settings, or create a new action.
Click on the Edit button in the top right corner.
Scroll down and check the Enable callback action checkbox, this will show additional input fields.
Choose the action that you want to execute as callback action within the Action dropdown.
Assign values to variables of the callback action if you want to forward and process values from the initial action.
Optionally, you can choose to enable the Execute all action in foreground checkbox, which sets the callback action to run in the foreground if this is set to background.
When you're done with setting up the action you can click the Save button in the top right corner to save it.
Be careful for:
Using callback on batch actions. A batch action is not seen as a single action, this will trigger the callback for each record.
Using callback on itself, which could lead to an infinite loop.
