Set response value as Variable in Test

[brcox9090]

I am trying to figure out how to set a response value as a variable using a Test script so I can pass that value along to another call. All the tutorials I’ve seen do this AFTER setting the value in a Pre-request script, and the logic provided for that doesn’t seem to if you’re not setting the value yourself.

The response I get when I make the API call is as follows:

I’d like to set the “id” value, which is “164070” as a variable called folderID that gets passed along to the next call.

Right now I have the following Test code written, but it’s returning the entire response body as the folderID value.

Any idea what I’m doing wrong?

You’re using pm.response.text() here which isn’t required for a JSON response, as you can use .json() to get the data in a format that’s easily parsable.

This is what you would need to get the first object’s id value:

let response = pm.response.json();
pm.environment.set('folderID', response.data[0].id);

Ensure that you have an environment file created and selected or it will not capture the variable.

I wrote this a while ago about getting different values from a JSON response, it may help you here:

Sharing tips and tricks with others in the Postman community

Extracting values from a JSON response I notice lots of questions from the community which all have a similar flavour - Users are having trouble extracting data from a JSON response body when the value is within an array. These are normally JavaScript related questions, more than specific Postman questions but I want to use this thread to offer more support around this problem. For these examples I’ll be using the https://randomuser.me API, this returns lots of random user data, in a JSON form…

Thank you for the help! This worked exactly the way I’d expected!
