How to nest parameters in Postman - arrays

Question

I am trying to configure an API call with an array in Postman, but I'm unable to figure out how to properly configure my parameters so that the Items and Properties appears as they do in the sample below. I can't quite figure out how to next Items > Item > Properties > Property
Here's a screenshot of what I need to send should look like
I feel like I might be getting close, but it's still wrong.
Here's a screenshot of my last attempt

Answer 1

It is possible by Postman Variable and hierarchy JSON access method.
Steps Overview
I will shows simple demo and apply your case.
Simple Demo
Demo - I will show ADD operation in Calculator SOAP
SOAP service URL
http://www.dneonline.com/calculator.asmx
Using variables input_a, input_b for adding
1. Assign Variable
JSON input
var jsonData = {
"key_a" : {
"data" : "2"
},
"key_b": {
"data" : "3"
}
}
input_a = jsonData["key_a"]["data"] = 2
input_b = jsonData["key_b"]["data"] = 3
In Pre-request Script section in Postman
2. Apply XML
<?xml version="1.0" encoding="utf-8"?>
<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/">
<soap:Body>
<Add xmlns="http://tempuri.org/">
<intA>{{input_a}}</intA>
<intB>{{input_b}}</intB>
</Add>
</soap:Body>
</soap:Envelope>
In input Body section in Postman
3. SOAP/POST Call
In outputBody section in Postman
4. XML Parsing
In Tests section in Postman
var xmlTree = xml2Json(responseBody);
var text = xmlTree["soap:Envelope"]["soap:Body"]["AddResponse"]["AddResult"];
postman.setEnvironmentVariable("output_result", Number(text));
console.log(postman.getEnvironmentVariable("output_result"));
5. Result
output_result = input_a + input_b
5 = 2 + 3
Complicate Demo - your question
Apply in your case by same idea(Simple Demo)
1. Assign Variable at Pre-request Script
var jsonData = {
"username" : "tom",
"password" : "1234",
"subscriptionId" : "sub-125abdv1",
"items": [
{
"item" : {
"id" : "CN #00168927",
"properties" : [
{
"property" : {
"name" : "ssn",
"value" : "555-01-0001",
}
},
{
"property" : {
"name" : "lastName",
"value" : "James",
}
}
]
}
},
{
"item" : {
"id" : "CN #00927119",
"properties" : [
{
"property" : {
"name" : "firstName",
"value" : "Jack",
}
},
{
"property" : {
"name" : "lastName",
"value" : "Doyle",
}
},
{
"property" : {
"name" : "ssn",
"value" : "555-01-0002",
}
}
]
}
}
]
}
console.log("username = " + jsonData["username"]);
console.log("password = " + jsonData["password"]);
console.log("subscriptionId = " + jsonData["subscriptionId"]);
postman.setEnvironmentVariable("username", jsonData["username"]);
postman.setEnvironmentVariable("password", jsonData["password"]);
postman.setEnvironmentVariable("subscriptionId", jsonData["subscriptionId"]);
console.log("items[0] id = " + jsonData["items"][0]["item"]["id"]);
postman.setEnvironmentVariable("item_zero_id", jsonData["items"][0]["item"]["id"]);
console.log("items[0] properties[0] name = " + jsonData["items"][0]["item"]["properties"][0]["property"]["name"]);
postman.setEnvironmentVariable("item_zero_property_zero_name", jsonData["items"][0]["item"]["properties"][0]["property"]["name"]);
console.log("items[0] properties[0] value = " + jsonData["items"][0]["item"]["properties"][0]["property"]["value"]);
postman.setEnvironmentVariable("item_zero_property_zero_value", jsonData["items"][0]["item"]["properties"][0]["property"]["value"]);
console.log("items[0] properties[1] name = " + jsonData["items"][0]["item"]["properties"][1]["property"]["name"]);
postman.setEnvironmentVariable("item_zero_property_one_name", jsonData["items"][0]["item"]["properties"][1]["property"]["name"]);
console.log("items[0] properties[1] value = " + jsonData["items"][0]["item"]["properties"][1]["property"]["value"]);
postman.setEnvironmentVariable("item_zero_property_one_value", jsonData["items"][0]["item"]["properties"][1]["property"]["value"]);
console.log("items[1] id = " + jsonData["items"][1]["item"]["id"]);
postman.setEnvironmentVariable("item_one_id", jsonData["items"][1]["item"]["id"]);
console.log("items[1] properties[0] name = " + jsonData["items"][1]["item"]["properties"][0]["property"]["name"]);
postman.setEnvironmentVariable("item_one_property_zero_name", jsonData["items"][1]["item"]["properties"][0]["property"]["name"]);
console.log("items[1] properties[0] value = " + jsonData["items"][1]["item"]["properties"][0]["property"]["value"]);
postman.setEnvironmentVariable("item_one_property_zero_value", jsonData["items"][1]["item"]["properties"][0]["property"]["value"]);
console.log("items[1] properties[1] name = " + jsonData["items"][1]["item"]["properties"][1]["property"]["name"]);
postman.setEnvironmentVariable("item_one_property_one_name", jsonData["items"][1]["item"]["properties"][1]["property"]["name"]);
console.log("items[1] properties[1] value = " + jsonData["items"][1]["item"]["properties"][1]["property"]["value"]);
postman.setEnvironmentVariable("item_one_property_one_value", jsonData["items"][1]["item"]["properties"][1]["property"]["value"]);
console.log("items[1] properties[2] name = " + jsonData["items"][1]["item"]["properties"][2]["property"]["name"]);
postman.setEnvironmentVariable("item_one_property_two_name", jsonData["items"][1]["item"]["properties"][2]["property"]["name"]);
console.log("items[1] properties[2] value = " + jsonData["items"][1]["item"]["properties"][2]["property"]["value"]);
postman.setEnvironmentVariable("item_one_property_two_value", jsonData["items"][1]["item"]["properties"][2]["property"]["value"]);
2. Apply XML
<?xml version="1.0"?>
<AddPortfolioItemsRequest xmlns="http://www.bkwservice.com/api/2022-08-01">
<username>{{username}}</username>
<password>{{password}}</password>
<subscriptionId>{{subscriptionId}}</subscriptionId>
<items>
<item>
<id>{{item_zero_id}}</id>
<properties>
<property>
<name>{{item_zero_property_zero_name}}</name>
<value>{{item_zero_property_zero_value}}</value>
</property>
<property>
<name>{{item_zero_property_one_name}}</name>
<value>{{item_zero_property_one_value}}</value>
</property>
</properties>
</item>
<item>
<id>{{item_one_id}}</id>
<properties>
<property>
<name>{{item_one_property_zero_name}}</name>
<value>{{item_one_property_zero_value}}</value>
</property>
<property>
<name>{{item_one_property_one_name}}</name>
<value>{{item_one_property_one_value}}</value>
</property>
<property>
<name>{{item_one_property_two_name}}</name>
<value>{{item_one_property_two_value}}</value>
</property>
</properties>
</item>
</items>
</AddPortfolioItemsRequest>
