I’m currently working on an HTTP monitor where I don’t know how to validate the JSON response.

It is a [status.io](http://status.io) endpoint that I would like to query, but the JSON response contains more info than I need. Is it possible to isolate two objects with post-execution scripts prior to validation? Let’s say I wanted to validate on **Voice DK** & **Agent application** status.

If anyone could point me in the right direction it would be much appreciated&nbsp;:blush:

**Endpoint** :  
[https://api.status.io/1.0/status/58207f2bf02471510e000303](https://api.status.io/1.0/status/58207f2bf02471510e000303)

You will need to parse the json with javascript code.

Example:

```markup
{
    "totalCount": 3,
    "nextPageKey": null,
    "resolution": "1m",
}

```

```javascript
body = response.getResponseBody();
obj = JSON.parse(body);
totalCount = obj.totalCount;
api.setValue("totalCount", totalCount);
if (totalCount == 0) {
    api.fail("Total Count is null");
} else {
    api.info("Total Count is not null");
}

```

You just need to proper parse the result json you get from the status page to get the proper field for validation.
