How to loop over array to change input of request?

New to APIs/Postman
15

Guys, thanks a lot… you got me to a point where I have a script, that is doing what I want it to do.

Now I just have one question left, which is less technical (hopefully):
Every request is responding with a JSON file with the wanted information. How can I save these responses during the loop … or… where can I find it?
After the successful run of the Runner I can choose -> Export Results. But this is giving me a report of the run (i.e. running time etc.).

How can I find the actual responses of the API?

If someone is interested here the code that works:

Pre-request:

// Load the latitude and longitude arrays from the environment

const latitudeArray = JSON.parse(pm.environment.get('latitudeArray')); // Parse from string to array

const longitudeArray = JSON.parse(pm.environment.get('longitudeArray'));

// Check array by log.output

console.log(latitudeArray)

// Load the current index 

const index = parseInt(pm.environment.get('latLongIndex')); //Parse from string to Integer

// Some log.outputs to follow what's happening

console.log("The value of the index is " + index);

console.log((index+1)+". entry of array: "+ parseFloat(latitudeArray[index]));

// Set the variables for this iteration and increment the counter

pm.environment.set('latitude', parseFloat(latitudeArray[index]));

pm.environment.set('longitude', parseFloat(longitudeArray[index]));

pm.environment.set('latLongIndex', (index+1));

Test:

const latitudeArray = JSON.parse(pm.environment.get('latitudeArray'));

const longitudeArray = JSON.parse(pm.environment.get('longitudeArray'));

const index = parseInt(pm.environment.get('latLongIndex'));

// Check to see if we need to do another loop

if(index < latitudeArray.length && index < longitudeArray.length) {

  // If another loop is required, set the next request to this one. 

  postman.setNextRequest("RequestName");

}

else {

  // If another loop is not required, set index back to 0 for next time.

pm.environment.set('latLongIndex', 0);

}
