# Amazon Publisher Services (APS)

Amazon Publisher Services (APS) uses its own dedicated Unity plugin and requires a different installation process than other ad providers.

If your project requires APS, your Lion Studios manager will advise when APS should be installed and configured, and will provide the required settings.

LionSDK provides a streamlined way to install and manage the APS Unity plugin within your project.

### Installation

In Unity, open the Lion Manager window by navigating to:\
Window → Lion Studios → Settings Manager

Open the Amazon section from the left-hand navigation.

If APS is not installed, click Install.

After installation is complete, enable Auto Initialization.

Enter the required APS settings provided by your Lion Studios manager.

The APS installation is now complete!

#### Lion Ads

If you are using Lion Ads, APS can now be configured in the Ads section of Lion Manager. Enter the required APS ad unit settings for each supported platform. For more information, please refer to this [section](/readme/features/ads/third-party.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://lionstudios.gitbook.io/readme/features/ads/third-party/amazon-publisher-services-aps.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
