Hello Everyone,  
I am getting an array as a response. Now I want to post the data to the slack for each object inside that array.  
I want to know how to run a postman.setNextRequest(‘COLLECTION\_NAME’); multiple times so that I can post the data multiple time.

```
array.forEach((item,index) => {
    pm.environment.set("photo_thumb", item.photo.thumb);
    postman.setNextRequest("Post Data to Slack")
});

```

This code is overwriting the photo\_thumb environment variable and postman.setNextRequest run only one time and it post only last data of the array.  
How should I run the post request multiple times?  
Or please tell me some other way of doing that.  
Thank You

```
   //assume this is the response array 
   array = [1, 2, 3, 4, 5]

    if (!Number(pm.environment.get('temp'))) {

        pm.environment.set("array", array)

        pm.environment.set('temp', 1)

    }

    let arr = pm.environment.get("array")

    console.log(arr)

    if (arr.length !== 0) {

        if (arr.length !== 1) {

            postman.setNextRequest(pm.info.requestName)

        }

        pm.environment.set('value', arr.pop())

        pm.environment.set("array", arr)

    } else {

        pm.environment.set('temp', 0)

    }

```

You cannot use it in a simple for loop , instead create a varaible ‘temp’ with value 0 , ( One time setup)
