////

If a client tries to send some **extra** data in the **query parameters**, they will receive an **error** response.

For example, if the client tries to send a `tool` query parameter with a value of `plumbus`, like:

```http
https://example.com/items/?limit=10&tool=plumbus
```

import okhttp3.MediaType.Companion.toMediaType
import okhttp3.OkHttpClient
import okhttp3.Request
import okhttp3.RequestBody.Companion.toRequestBody

class PostString {
  private val client = OkHttpClient()

  fun run() {
    val postBody =
      """

- `account` client_id is a confidential client that belongs to the realm `{realm}`
- `account` client_id is has **Service Accounts Enabled** option enabled.
- `account` client_id has a custom "Audience" mapper, in the Mappers section.
  - Included Client Audience: security-admin-console

#### Adding 'admin' Role

- Go to Roles

    the key value sent in the query parameter automatically and provides it as the
    dependency result. But it doesn't define how to send that API key to the client.

    ## Usage

    Create an instance object and use that object as the dependency in `Depends()`.

    The dependency result will be a string containing the key value.

    ## Example

    ```python

 *     if (myConfig.isInvalid()) {
 *       return Response.Builder()
 *           .request(chain.request())
 *           .protocol(Protocol.HTTP_1_1)
 *           .code(400)
 *           .message("client config invalid")
 *           .body("client config invalid".toResponseBody(null))
 *           .build()
 *     }
 *
 *     return chain.proceed(chain.request())
 *   }
 * ```
