# Prerequisites

### Creating an app

*Let's get going!*

The very first step is to go to [Batch's dashboard](https://dashboard.batch.com/) and create a new app.

![Registering a new app](https://38998153-files.gitbook.io/~/files/v0/b/gitbook-x-prod.appspot.com/o/spaces%2FCL8wF0y1T2vLnm3yR2MW%2Fuploads%2F2M99Uu7clJeVP8yDmjJy%2Fdashboard_new_app_screenshot.png?alt=media\&token=5f1c4b1f-38f7-43f2-b151-7f828dd0b49c)

Now let's do all the required configurations to allow you to send notifications on iOS *(APNS)* and Android *(FCM)*.

### Setting up your apps

Here is how to set up your apps on Batch's dashboard:

* **iOS**: Download/upload a [.p8 file](/developer/sdk/ios/prerequisites.md#configuring-notifications) *(recommended)* or use a [.p12 certificate](https://doc.batch.com/developer/sdk/flutter/pages/LGYgNVUG2DhMZicjx5p6#generating-the-.p12-certificate).
* **Android**: [Get your Server API Key](/developer/sdk/android/prerequisites.md) and your sender ID.

Once you are done with APNS/FCM setup, you can start integrating the SDK into your app.

# Agent Instructions
This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

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

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://doc.batch.com/developer/sdk/flutter/prerequisites.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

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.
