postman: save response on a global variable - postman

Question

With PostMan, how can save the follow response:
[
{
"id": "6254c754-5a97-43fd-9b48-c428b9bd69e5",
"name": "fdsfds",
"description": "fdzf",
"type": 0,
"createDate": "2018-08-01T17:49:29.071+01:00",
"lastUpdateDate": "2018-08-01T17:49:29.071+01:00",
"lastUpdateUser": null,
"variables": null,
"instructions": null
}
]
on a variable? For example the id?
var jsonData = pm.response.json();
console.log(jsonData.id);
pm.globals.set("variable_key", jsonData.id);

Answer 1

to set the environment variable "authkey" from response
var obj = pm.response.json()["token"];
pm.environment.set("authkey", obj);

Answer 2

You can't save JS Objects directly in a global variable but you can use JSON library to convert your object to string and save, like the following code:
// create the JS Object
var obj = {
foo: "bar",
some_number: 91
}
// convert the obj to string and save in the globals
pm.globals.set("my_obj", JSON.stringify(obj));
// get obj from globals and parse to JS Object again
var obj_from_globals = JSON.parse(pm.globals.get("my_obj"));
// print int he console
console.log(obj_from_globals);
You should expect this in your console:

Answer 3

I think i resolve this with:
var jsonData = pm.response.json();
for (var key in jsonData) {
if (jsonData.hasOwnProperty(key)) {
var seqDelete = jsonData[key].id;
console.log(seqDelete);
}
}
pm.globals.set("seqDelete", seqDelete);
This isn´t totally correct.
If i have multidimension array, this only gets one ID value

Answer 4

This is the response that I work with:
{id: "myId", version: "2.0", name: "test"…}
This is how I set the id value from the response into my global variable "appId":
var requestJson = JSON.parse(request.data);
console.log(requestJson)
postman.setGlobalVariable("appId", requestJson.id);
Result:
