Condition: Array of Objects Contains Field Matching

Posted on by WillShiell

Hello, I am attepting to write a flow that looks through an Array of Objects and determines if there is a matching value on a certain field.

Here is the structure of my Array of Objects:

[
 {
 "id": "ABC",
 "label":"ABC"
 },
 {
 "id": "BCD",
 "label":"BCD"
 },
 {
 "id": "CDE",
 "label":"CDE"
 }
]

Here is the structure I am trying to match against:

{
 "id":"ABC"
}

I want to build a condition such that if the id value is contained within the Array then evaluate true, but if its not contained within the array, evaluate false.

Using the Contains option within the Condition Connector is giving me false values everytime.

You habe to create a simple array (not a key value pair) to use contains.

But if you only want to check to that single object you could use something like:

equals(item()[‘id’], YOUROBJECT[‘id’])

Since this was a top result in my search for an answer, I thought I'd post an alternative--or an elaboration on the accepted answer for how you would create a simple array of values instead of key:value pairs:

You could add a Select action, specify your array as the source, and click on the text mode gadget on the right to switch from key:value mode to a single text box, then use the expression:

item()?['id']

And add just that to the Map: text field.

The outputs of that will be:

[

"ABC",

"BCD",

"CDE"

]

And you can then run contains() on that, or use a condition action with the select as the left side, contains as the operator, and ABC as the value on the right side.
