# Integrate

By following these steps, you’ll be prepared to provide the SHA-256 fingerprint of your app’s signing certificate and seamlessly integrate native-display checkout using our SDK.

### Prerequisites

**Keytool**: A command-line tool for managing Keystores and certificates, usually included with the Java Development Kit (JDK). Ensure the JDK is installed on your machine.

### Step 1: Generate a New Keystore

If you already have a Keystore for your application, you may skip this step.

1. Open your terminal.
2. Run the Keytool command:

<CodeGroup>
  ```shell shell theme={"system"}
  keytool -genkey -v -keystore your_keystore_path -alias your_alias -keyalg RSA -keysize 2048 -validity 10000
  ```
</CodeGroup>

* `your_keystore_path`: The location where you want to save the keystore file (e.g., `my-release-key.jks`).
* `your_alias`: The name you’ll use to refer to your key, typically your package name (e.g.,`com.org.name`).

### Step 2: Complete the Keystore Prompts

After running the command, you’ll be prompted to enter the following information:

1. **Keystore Password**: Choose a strong password to protect your keystore.
2. **Your Name**: Enter your name (or your organization’s name).
3. **Organizational Unit**: Optional; you can leave it blank.
4. **Organization Name**: Enter your organization’s name.
5. **City or Locality**: Enter the city where you are located.
6. **State or Province**: Enter the state or province where you are located.
7. **Country Code**: Enter the two-letter country code (e.g., US for the United States).

Confirm the details after entering them.

### Step 3: Extract SHA-256 Fingerprint

Once your keystore is generated, you can extract the SHA-256 fingerprint by running this command:

<CodeGroup>
  ```shell shell theme={"system"}
  keytool -list -v -keystore your_keystore_path -alias your_alias
  ```
</CodeGroup>

Replace `your_keystore_path` and `your_alias` with the values you used during keystore creation.

### Step 4: Find the SHA-256 Fingerprint

In the command output, find the line starting with `SHA256:`. Your fingerprint will look like this::

<CodeGroup>
  ```shell shell theme={"system"}
  SHA256: XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX:XX
  ```
</CodeGroup>

***Note:** This is a public key and does not contain sensitive information about your game.*

### Step 5: Submit the Details

Provide both the package name and the SHA-256 fingerprint to the Appcharge team for integration.
