title: How can I set an environment variable in postman from the response data received?
body: <p>My response body data:</p>
  
  <pre><code>  "slots": {
        "deliverySlots.today.text": {
          "list": [
            {
              "pos": "004",
              "deliverySlotCode": "8800652143353",
              "deliveryDate": "Mar 20",
              "beginTime": "10 am",
              "endTime": "12 pm",
              "dayOfWeek": "Tuesday",
              "selected": false,
              "expired": true,
              "isAvailable": true
            }
          ]
        }
      }
  </code></pre>
  
  <p>I would like to save the value of the <code>isAvailable</code> property into an environment variable. How can I set this value?</p>
