# Parameters

## Query Parameters

In a URL, a query parameter is a part of the query string and defined after the question mark (`?`). Query parameters are used to pass additional information.

For example, in the URL `https://www.example.com/search?query=example&page=2` the query parameters are 'query' and 'page', with values 'example' and '2', respectively.

## Body Parameters

Body parameters can be used to send JSON data. Unlike query parameters, it's possible to define the data type of body parameters.

{% hint style="warning" %}
Body parameters are not available for `GET` requests.
{% endhint %}

For example, in a `POST` request which creates a new job listing, the body parameters might include the job's title, location, and salary.
