Jmeter combine Json extractor variables to pass into request

There's a certain web request which has the following response:

{
"data": {
    "articles": [
        {
            "id": "1355",
            "slug": "smart-device-connectivity's-impact-on-homes-workplaces",
            "title": "Smart device connectivity's impact on homes, workplaces",
            "published_at": "2022-01-28T21:30:00.000Z",
            "avg_rating": 0,
            "click_count": 60,
        },
        {
            "id": "1363",
            "slug": "you-need-to-nurture-and-amplify-human-capabilities",
            "title": "You need to nurture and amplify human capabilities",
            "published_at": "2022-01-28T19:00:00.000Z",
            "avg_rating": 0,
            "click_count": 22,
        }]}}

There are a total of 702 records which may increase or decrease over the coming months. Now I have been successfully able to extract ID & slug into separate variables. My aim is to pass these two variables into another request in the following format so that I can eventually run that 702 times or number of times = ID array or slug array size:

testurl.com/insight/${id}/${slug}

Example: testurl.com/insight/1355/smart-device-connectivity's-impact-on-homes-workplaces testurl.com/insight/1363/you-need-to-nurture-and-amplify-human-capabilities

I made use of Foreach controller & was able to pass slug but ID does not work. Does anyone know the solution?

If you're using ForEach Controller for iterating slug variable the id one needs to be handed a little bit differently:

• use __jm__ForEach Controller__idx pre-defined variable to get current iteration of the ForEach Controller
• use __intSum() function to increment it by 1 as the above variable is zero-based
• use __V() function to calculate the value of id_x variable

putting everything together:

testurl.com/insight/${__V(id_${__intSum(${__jm__ForEach Controller__idx},1,)},)}/${slug}
