How to iterate the foreach loop in JMeter - jmeter

Question

I got the array response from the one API and I passed to the response to the other API.
For example:
Response from one API is {status:200,data:{name:"Manikyam", selected_products:[1,2,3,4,5]}
I need to iterate the selected_products from the response using foreach or other loop which is suitable of this.
Iterations like:
http://dummy.com/product/1
http://dummy.com/product/2
http://dummy.com/product/3
http://dummy.com/product/4
http://dummy.com/product/5
I tried some ways like using forEach but I haven't any luck.

Answer 1

The below answer assumes that your response is a valid JSON looking like:
{
"status": 200,
"data": {
"name": "Manikyam",
"selected_products": [ 1, 2, 3, 4, 5 ]
}
}
Add JSON Extractor as a child of the request which returns the above JSON and configure it as follows:
Names of created variables: anything meaningful, i.e. product
JSON Path Expressions: $.data.selected_products.*
Match No: -1
Add ForEach Controller and configure it as follows:
Input variable prefix: product
Output variable name: product
That's it, if you add a Sampler as a child of the ForEach Controller, the controller will iterate all the variables so you will be able to refer each and every as ${product} where required like http://dummy.com/product/${product}
