Set values from response to environmental variable array

I have a Postman POST request, where response body looks like this:

{
"data": [
    {
        "object": "Answer",
        "id": 507,
        ...
    },
    {
        "object": "Answer",
        "id": 208,
        ...
    }
],...

In following DEL request this ids should be used in body as array:

{
"ids": [id1, id2]
}

How can i get these ids from response and store it as environment variable array [id1, id2] so then it could be used like "ids": {{answer_ids_array}} ?

To capture the id values as an array and set in an environment variable you could add something like this to the Tests tab of the first request:

let myArray = []
_.each(pm.response.json().data, (item) => {
    myArray.push(item.id)
})

pm.environment.set("idArray", myArray)

To use the array in the request body, you would need to add this to the Pre-request script to transform to saved string back into an array:

pm.environment.set("ids", JSON.stringify(pm.environment.get("idArray")))

Your request body would then be something like this:

{
    "ids": {{ids}}
}
