Getting response from Postman in script

Question

I want to get the value of token from response of Postman and set it to an environment.

My response is showing like :

{
  "success": true,
  "token": "ojkdd"
}

and my script is :

pm.test(responseBody, true)
var jsonData = JSON.parse(responseBody);
console.log(jsonData)

I get the following error :

ReferenceError: responseBody is not defined

Answer 1

your json data is in pm. So you need to retrieve your JSON data using the below code.

 var jsonData = pm.response.json(); 

 pm.test("Verify Json values", function () { 
  pm.expect(jsonData.success).is.to.equal(true); 
 });

Edit : For setting it to environment as @danny suggested

 pm.environment.set("token", pm.response.json().token)

Answer 2

You did this same wrong way as I today :D the script should be in test not in Pre-request Sript

For response: { "token" : "kj32n4jk32n4" }

Past below script to TEST tab in postman and debug it in postman console

var data = JSON.parse(responseBody)
console.log(data.token)
postman.setEnvironmentVariable('token',data.token) 

Answer 3

If you want to store the value as an environment variable, you can add this to the Tests tab:

pm.environment.set("token", pm.response.json().token)

You will need to ensure that you have created an environment file and it's selected in the top right of the UI, before the variable can be stored.
