Hi,

I am new to Power Automate however with decent coding skills in typescript ( my background)

Question: I am struggling to update the array elements within JSON with a set of values in hand.

I want to create a final payload for my API call from different sources to make it simple here is my problem statement:

1. If I have a BaseJson Object variable as mentioned below

BaseJson = {
"app": 1,
"names": []
}

2. An array variable of names of type array as below.

[
"cy",
"tt"
]

I wish to construct the final object as mentioned below without using string manipulation.

FinalJson = {
"app": 1,
"names": ["cy",
"tt"]
}

I've made a test for your reference:

My flow:

addProperty(removeProperty(variables('BaseJson'),'names'),'names',variables('TheArray'))

Result:

Best Regards,
