Extract value of a dynamic key from response

Question

I have a response as below:

{
    "value": {
        "element-6066-11e4-a52e-4f735466cecf": "b721a18e-ffab-49bc-acdf-5a30c84e160d"
    }
}

I want to extract the value of they dynamic key labelled "element-6066-xxxx-xxxx-xxxxxxxxx" (changes each time I re-run the API call).

Any guidance would be greatly appreciated.

I tried the following:

var data = JSON.parse(responseBody);
pm.environment.set("elementId", Object.keys(data.value)[0]);

But this sets the "key" instead of the "value" (expecting 'b721a18e-ffab-49bc-acdf-5a30c84e160d' to be set.

What's this got to do with Groovy? It's javascript isn't it? — tim_yates, Aug 25 '23 at 13:43

You would need to use Object.values() for this:

let res = pm.response.json();
pm.environment.set("elementId", Object.values(res.value)[0]);

The Object.values() would help you. you can refer to this MDN docs. Here is an example of that:

let x = {
    "value": {
        "element-6066-11e4-a52e-4f735466cecf": "b721a18e-ffab-49bc-acdf-5a30c84e160d"
    }
}

console.log(Object.values(x.value)[0])

This is still logging out the `key` and not the `value`. – Danny Dainton Aug 25 '23 at 17:21
Thanks for the comment, I suggested to use values but kept the keys in the logs lol, just changed it to values! – a0m0rajab Aug 26 '23 at 19:32
