Hi Guys .. during response template how  i can check if request json contains a key and if available get the val and return back in the response else return 0 or something else. Something as below
however when request has no query.offset then i am returning a blank val which crash the app


```  "offset": {{request.query.offset}},```

Do you mean your request is a json payload that has a structure like:
```{
"query": {
"offset": 1
}
}```


If the above is a correct assumption then you can use the `jsonPath` helper to pull the value out of the request.  The nice thing is that the `jsonPath` helper allows you to specify a default.  So, create your response along the lines of:
```{
    "myOffset": {{jsonPath request.body '$.query.offset' default='0'}}
}```
If you then send a request like this:
```{
    "query": {
      "offset": 4
    }
}```
You will get a response like this:
```{
  "myOffset": 4
}```
If you send a request like this:
```{
    "query": {
      "foo": "bar"
    }
}```
You will get a response like this:
```{
  "myOffset": 0
}```
