Sending a request without specifying the fields in the body - csv

Question

I'm trying to send several PUT request to a specific endpoint.
I am using a CSV file within the columns and values, the name of the different columns reference the different variables inside the body, do you get me?
This is the endpoint:
{{URL_API}}/products/{{sku}} --sku is the id of the product, i created that variable because i use it to pass the reference
This is the body that i use:
{
"price":"{{price}}",
"tax_percentage":"{{tax_percentage}}",
"store_code":"{{store_code}}",
"markup_top":"{{markup_top}}",
"status":"{{status}}",
"group_prices": [
{
"group":"{{class_a}}",
"price":"{{price_a}}",
"website":"{{website_a}}"
}
]
}
I don't want to use the body anymore.. sometimes some products have more tan 1 group of prices, i mean:
"group_prices": [
{
"group":"{{class_a}}",
"price":"{{price_a}}",
"website":"{{website_a}}"
},
{
"group":"{{class_b}}",
"price":"{{price_b}}",
"website":"{{website_b}}"
}
Is it possible to create something like this in the CSV file?
sku,requestBody
99RE345GT, {JSON Payload}
How should i declare the {JSON Payload}?
Can you help me?
EDIT:
This is the CSV file i used:
sku,price,tax_percentage,store_code,markup_top,status,class_a,price_a,website_a
95LB645R34ER,147000,US-21,B2BUSD,1.62,1,CLASS A,700038.79,B2BUSD
I want to pass the JSON within the CSV file, i mean
sku,requestBody
95LB645R34ER,{"price":"147000","tax_percentage":"US-21","store_code":"B2BUSD","markup_top":"1.62","status":"1","group_prices":
[{ "group":"CLASS A","price":"700038.79","website":"B2BUSD"}]}
Is it okay?Should i specify anything on the request body or not? I read the documentation posted in POSTMAN website but i did not find an example like this.

As you're using JSON data as a payload, I would use a JSON file rather than a CSV file in the Collection Runner. Use this as a template and save it as data.json, it's in the correct format accepted in the Runner.
[
{
"sku": "95LB645R34ER",
"payload": {
"price": "147000",
"tax_percentage": "US-21",
"store_code": "B2BUSD",
"markup_top": "1.62",
"status": "1",
"group_prices": [
{
"group": "CLASS A",
"price": "700038.79",
"website": "B2BUSD"
}
]
}
},
{
"sku": "MADEUPSKU",
"payload": {
"price": "99999",
"tax_percentage": "UK-99",
"store_code": "BLAH",
"markup_top": "9.99",
"status": "5",
"group_prices": [
{
"group": "CLASS B",
"price": "88888.79",
"website": "BLAH"
}
]
}
}
]
In the pre-request Script of the request, add this code. It's creating a new local variable from the data under the payload key in the data file. The data needs to be transformed into a string so it's using JSON.stringify() to do this.
pm.variables.set("JSONpayload", JSON.stringify(pm.iterationData.get('payload'), null, 2));
In the Request Body, add this:
{{JSONpayload}}
In the Collection Runner, select the Collection you would like to run and then select the data.json file that you previously created. Run the Collection.
