# Using Query Params

When working on a mock API, you will often need to configure your API in a way that will affect the working of the rest of your team. So to handle those scenarios, Mocklets enables you to control some of the configuration using query params while making the API request.

Currently, we allow users to configure response HTTP status and delay parameters by adding query params to their API calls.

### Configure HTTP Status

You can request a specific HTTP status in response by adding `x_response_status` param to your api. So, if you api is `https://api.mocklets.com/mock12675/pets` which has its active response HTTP status set as `200`, but you want it to return a `401` response, you just have to call

```http
https://api.mocklets.com/mock12675/pets?x_response_status=401
```

{% hint style="info" %}
**Please note** You need to add the requested status code to your api, otherwise it will return `404 NOT FOUND`  error.
{% endhint %}

### Configure Response delay

User can add custom delay to the api request using query param without effecting the behavior of other team members using the same api. You need to add `x_response_delay` param to you api. So, if your api is `https://api.mocklets.com/mock12675/pets` and you want to set the delay as `15 seconds`, you have to call

```http
https://api.mocklets.com/mock12675/pets?x_response_delay=15
```

The maximum delay supported in `60 seconds`, any value above it will be ignored and `60 second` delay will be set for that request.

We are adding more configuration that can be managed using query params. Please stay tuned for more.
