Data variables

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

External data variables

You can use external data variables to display data from third-party services in a Nintex Workflow Government Edition 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 .

Create external data variables from the Data variables tab

1. Open a form and click the Data variables tab.

2. From the options on the left, select External data.

3. Click Create variable.

4. Specify a Name.

   Note: 

   Variables names must adhere to the following naming conventions to support localization:

   • Must be at least 1 non-whitespace character.

   • Cannot contain newline or paragraph characters.

   • Cannot contain HTML as it contains unsupported characters like <, >, and /.

   • Cannot begin with a number.

   • Cannot contain any of the following characters: +, -, !, *, ", /, >, >=, <, <=, =, ==, !=, &, &&, |, ||, ., , (comma), [, ], (, ), and \n

5. Specify a data lookup.

   Fields are displayed depending on the specified data lookup and the Connector linked to the data lookup. For information on the supported Connectors, see Supported data lookups.

6. Specify the required details related to the data lookup.  

   Note: When configuring a condition for the external data variable, you can currently use only form variables or form controls.

   For more information on data lookups and Connector fields, see Data lookups and Connectors.

7. Click Create variable.

   The variable is added to the list of variables. You can click an object variable from the list to view the variables it contains.

   Note: 

   • To use the variables, insert the external data variables from a Label control or a form rule. For more information, see External data .

   • If you want to deny form submissions when external variables have errors, do not resolve, or time out, go to the General settings page to enable or disable the toggle for form submissions. For more information, see Forms settings.
