Postman - Looping through an array of nested objects to make a variable

I am trying to set a variable from following phone number with value: “+33652556777” (index 4 in JSON attached below) which is the last object in contacts (index 4).

To do so is pretty simple:

let jsonData = pm.response.json();
console.log (jsonData.contacts[4].phone_numbers[0].value)  
const PhoneNumber = jsonData.contacts[4].phone_numbers[0].value
pm.environment.set("Jacky", PhoneNumber);

Since I have to use different query parameters to filter by eg. created_at=asc, desc, the property of the phone_numbers order might change index number and I won’t be able to fetch desire phone number "+33652556777” instead it will set a different phone number which I cannot allow.

I know there is way to fetch our number and make it variable for next requests, which is iterating over properties or keys in the object “ for….in or for…of ” but for some reason I cannot achieve it.

What I could achieve is to get through first object “contacts” but impossible to get to its nested array “phone_numbers”. Here is how I did it:

let jsonData = pm.response.json();
let contact;
for (let filter of jsonData.contacts){
if (filter.last_name == "Rowland"){
   contact = filter;
}} 
console.log (contact);

Could you please help?

Here goes the JSON body response:

you can use forEach or _.each as danny mentioned to get all numbers else use:

console.info(jsonData.contacts.find((a)=>a.first_name==="Jacky").phone_numbers[0].value)

use array.find to find the contact with first_name jacky adn then get phone_number[0].value from it.

if you want all numbers from that array then use:

console.info(jsonData.contacts.find((a)=>a.first_name==="Jacky").phone_numbers.map((a)=>a.value))

here we map the result to get only the numbers from phone_number array.

is it what you looking for !?

You could use something basic like this:

_.each(pm.response.json().contacts, (contact) => {
    if(contact.last_name === "Rowland") {
        pm.environment.set(`${contact.first_name}_${contact.last_name}_number`, contact.phone_numbers[0].value)
    }
})

There are probably better and more performant ways to do this but if you just want to set a variable for that contact, no matter where they are in the response - This would work :D
