Data variables

In the Data variables tab, you can manage and view external data variables and table data variables for your forms.

External data variables

You can use external data variables to display data from third-party services in a Nintex Automation Cloud form. The Data variables tab allows you to easily add, modify, or remove external data variables without the need to add them to a Label control or rule.

If you click an object or collection variable from the list in the External data section, you can view all variables it contains. A path is also displayed on top of the list to help you track the variable you selected.

For more information, see External data .

You can use Table data variables to reference and display data from a Nintex Table in a Nintex Automation Cloud form. In the Data variable tab, you can add, edit, or delete table variables
