# Amazon Publisher Services (APS)

Amazon's mobile app ad solution, Amazon Publisher Services (APS), has a dedicated Unity plugin and requires a different installation process than other ad providers.

## Installation

{% hint style="success" %}
Please be sure you have [Lion SDK](/readme/getting-started.md) installed in your project.
{% endhint %}

1\. Open **Lion Studios** > **Settings Manager** on Unity's navigation bar.

4. Installation is complete at this point.

### Update Amazon Id's

1. Ask your studio manager to put Amazon app Id's and Amazon ad Id's for both android & iOS on Portal side.
2. Run Setup Wizard again by going to **LionStudios -> Setup Wizard** and complete all steps.

   1. Once you reach "Issues are Detected" step, click on "Fix it" button for "Ads identifier mismatch". All ids will get added automatically at correct locations.
   2. **Note**: If all Amazon Ad's are already added correctly at this point then following button will not show up and it means that setup is already configured correctly.

### Sanity Check:

This step is not required but if you want you can see all Amazon Id's for yourself too.

1. Go to **LionStudios -> Settings Manager -> Amazon.** You will see Amazon Android and iOS App IDs there already.

{% hint style="success" %}
Be sure you other **Ad Unit IDs** are filled and keep "**Enable Lion Ads**" on. See more information here [Ads](/lionsdk-1.x-legacy-docs/ads.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/third-party-sdks/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.
