Removes duplicates from a list of objects.

Input

Field Definition Type Required

List

A list of objects that contains the duplicates you want to remove.

 List of Objects TRUE

Path

While List is a list of objects, Path is the name of the key that determines whether something is a duplicate or not.

For example, you may want just one customer record per unique email address.

 Text TRUE

Output

Field Definition Type

List No Duplicates

A list of objects with the duplicate items removed.

 List of Objects

To filter out duplicates using more complex criteria than a single value or key, use the Unique Custom function. This function calls a helper flow to determine the value for each item and determines if it's unique or not.

Example

Consider the following elements in a list of defined objects:

[
  {
    "name": "Nicole",
    "value": 10
  },
  {
    "name": "Sarah",
    "value": 20
  },
  {
    "name": "Emily",
    "value": 10
  }
]

If the input for the Path is value, then the returned List No Duplicates has only one object with the value of 10:

[
  {
    "name": "Nicole",
    "value": 10
  },
  {
    "name": "Sarah",
    "value": 20
  }
]

If the input for the Path is name, then the returned List No Duplicates is unchanged:

[
  {
    "name": "Nicole",
    "value": 10
  },
  {
    "name": "Sarah",
    "value": 20
  },
  {
    "name": "Emily",
    "value": 10
  }
]
