isArray

isArray Task Purpose

The isArray task is used to check if an input is an array. The task returns a boolean ("true" or "false") result that indicates if the input was validated as an array or not.

Potential Use Case

Use the isArray task if you need to validate if a dataset was setup as an array. The task is generally used in the workflow after a task that does not have a constant outgoing variable type, such as an external API request that could return an array or a string.

Properties

Input and output parameters are shown below.

Example 1

In this IAP example:

• The arr variable is statically set and the Reference variable is ["1","2","3"].

  

• The outgoing result is true, indicating the input is an array.

  

Example 2

• The arr has a Reference variable of "1","2","3". Notice the square brackets "[]" are missing at the beginning and end of the variable.

  

• The task returns false, indicating the input value is not an array.
