# Adding general information about your API

## Authentication information
You can add authentication information for your API using the `auth` section in `scribe.php`. 

```eval_rst
.. Important:: Scribe uses your specified authentication information in three places:

   - Generating an "Authentication" section in your docs
   - Adding authentication parameters to your example requests for endpoints marked as :code:`@authenticated` (or if you have with :code:`auth.default` = true)
   - Adding the necessary auth parameters with the specified value to response calls only for endpoints marked as :code:`@authenticated` (or if you have with :code:`auth.default` = true)
```

Here's how you'd configure auth with a query parameter named `apiKey`:

```php
    'auth' => [
        'enabled' => true,
        'default' => false,
        'in' => 'query',
        'name' => 'apiKey',
        'use_value' => env('SCRIBE_API_KEY'),
        'placeholder' => 'YOUR-API-KEY',
        'extra_info' => 'You can retrieve your key by going to settings and clicking <b>Generate API key</b>.',
    ],
```

If `apiKey` were to be a body parameter, the config would be same. Just set `in` to `'body'`.

Here's an example with a bearer token (also applies to basic auth, if you change `in` to `'basic'`):


```php
    'auth' => [
        'enabled' => true,
        'default' => false,
        'in' => 'bearer',
        'name' => 'hahaha', // <--- This value is ignored for bearer and basic auth
        'use_value' => env('SCRIBE_AUTH_KEY'),
        'placeholder' => '{ACCESS_TOKEN}',
        'extra_info' => 'You can retrieve your token by visiting your dashboard and clicking <b>Generate API token</b>.',
    ],
```

And here's an example with a custom header:


```php
    'auth' => [
        'enabled' => true,
        'default' => false,
        'in' => 'header',
        'name' => 'Api-Key', // <--- The name of the header
        'use_value' => env('SCRIBE_AUTH_KEY'),
        'placeholder' => 'YOUR-API-KEY',
        'extra_info' => 'You can retrieve your token by visiting your dashboard and clicking <b>Generate API token</b>.',
    ],
```
The `default` field is the default behaviour of our API. If your endpoints are authenticated by default, set this to `true`, then use `@unauthenticated` on the method doc block if you need to turn off auth for specific endpoints. If your endpoints are open by default, leave this as `false`, then use `@authenticated` on the method doc block if you need to turn on auth for specific endpoints.

You can set whatever you want as the `extra_info`. A good idea would be to tell your users where to get their auth key. 

The `use_value` field is only used by Scribe for response calls. It won't be included in the generated output or examples.
The `placeholder` is the opposite of `use_value`. It will be used only as a placeholder in the generated example requests.

For more information, see the [reference documentation on the auth section](../config.html#auth).


## Introductory text
The `intro_text` key in `scribe.php` is where you can set the text shown to readers in the "Introduction" section. If your text is too long to be put in a config file, you can create a `prepend.md` containing the intro text and put it in the `resources/docs` folder.

## Title
You can set the HTML `<title>` for the generated docs webpage, Postman collection and OpenAPI spec by setting the `title` key in `scribe.php`. If you leave it as null, Scribe will infer it from the value of `config('app.name')`.

## Logo
Maybe you've got a pretty logo for your API or company, and you'd like to display that on your documentation page. No worries! To add a logo, set the `logo` key in `scribe.php` to the path of the logo. Here are your options:

- To point to an image on an external public URL, set `logo` to that URL.
- To point to an image in your codebase, set `logo` to the `public_path()` of the image, if you're using `laravel` type docs. If you're using `static` type, pass in the relative path to the image from the `public/docs` directory. For example, if your logo is in public/images, use '../img/logo.png' for `static` type and 'img/logo.png' for `laravel` type.
- To disable the logo, set `logo` to false.
