Definition and Usage
Merge lists combines two separate lists into a single unified list. This action allows you to concatenate the elements from two different list variables, creating a new merged list that contains all items from both source lists.
Parameter Values
Input parameters
Parameter | Description | Possible Values | Required | Options / Notes |
List 1 | Select the first list to merge | Any list variable | Yes | The first source list that will be combined |
List 2 | Select the second list to merge | Any list variable | Yes | The second source list that will be combined |
Error handling
Parameter Name | Description |
Throw error & stop | When an error occurs, the action will trigger an error and stop the execution of the entire app. |
Retry command | If an error occurs, the action will retry the command in an attempt to resolve the issue and continue the process. |
Ignore error & continue | When an error occurs, the action will be ignored, and the workflow will continue without interruption. |
Variables produced
This action produces a new list variable that contains all elements from both source lists combined into a single list.
Using Variables in Conditions
When configuring this action, you can use existing variables by clicking the {x} icon next to input fields. This allows you to dynamically select source lists based on variables defined earlier in your workflow. The output variable can be referenced in subsequent actions when you need to work with the merged list.
Notes
The items from List 1 will appear first in the merged list, followed by items from List 2.
Both source lists must be valid list variables; attempting to merge non-list variables will result in an error.
The merged list will maintain the original order of items from both source lists.
If either source list is empty, the merge will still work, containing only the items from the non-empty list.
The data types of items in both lists can be different; the merge operation simply combines the items without type checking.
