Retrive data from json response

Hi Im having trouble rtrieving an integer value from a json respone and putting it into a variable

example of the json

“data”: {
“2020-09-29”: {
“37677760”: [
“Code”: 11111111,
“Type”: “data1”,
“CodeDate”: “2020-09-29”,
“Time”: “08:30”,
“ADate”: “29 Sep 2020”,
“data2”: 1,
“data3”: 45,
“data4”: 3766077777,
“sata5”: 127,
“Status”: “Past”,
“data6”: 2110738111,

i need to retrieve data4
currently I have

let response = pm.response.json(), savedData = JSON.stringify(response);

pm.environment.set(“savedData”, savedData);

This stores the whole response

many thanks

Hey @armygrad24

You could try the below expression to retrieve the “Data4” value


I have also uploaded a screenshot of the JSON evaluator expression for your reference

Hope this helps you.

This is a pretty specific path to the data, are you looking for something that is generic or something that finds exactly this piece of data? Meaning, I see the response has today’s date and some random number in there. Plus there is an array of objects.

If you want to get to data4 with the current response, you can make your code be like this:

const jsonData = pm.response.json();
const data4 =['2020-09-29'].37677760[0].data4;
pm.environment.set('savedData', data4);

I’m assuming you wanted just the integer value of data4 in the savedData variable.


But im getting the following error

kamalshree2784would that be placed in tests?

Maybe it doesn’t like the numbers as variables. The alternative would be like this:

const jsonData = pm.response.json();
const data =['2020-09-29']['37677760'][0]['data4'];
pm.environment.set('savedData', data);


That worked thank you so much you are the best

Thanks again armygrad

is there anyway of using a variable for the date, instead of hard coding the date

Thanks in advance

Yes there is.

let moment = require('moment');
const today = moment().format('YYYY-MM-DD');

const jsonData = pm.response.json();
const data =[today]['37677760'][0]['data4'];
pm.environment.set('savedData', data);

Again many Thanks, That worked perfectly

const jsonData = pm.response.json();
const data =[today][‘37677760’][0][‘data4’];
pm.environment.set(‘savedData’, data);

how do i set savedData as a global variable?

Instead of doing pm.environment.set just use pm.globals.set
