Hi,

I’m trying to set a variable from my response, but while the variable is being created there is no value assigned… below is my response

Here’s my variable set
var jsonData = JSON.parse(responseBody);postman.setGlobalVariable(“TZDelDoor”, jsonData.ID);

and here is my variable that has been created

any ideas?

My variables get created without any issues when the api response doesn’t have

@JohnF75 This is because your response is in an array.

Try something like this:
var jsonData = JSON.parse(responseBody);postman.setGlobalVariable(“TZDelDoor”, jsonData[0].ID);

No worries mate.

Whenever you’re dealing with an array that contains objects, you want to specify in the square brackets which item in the array you want to target - the first item in the array is 0, the second is 1 etc.
