# 2. Onboarding

## Provide onboarding data

Before you start integrating the NFC Wallet SDK, exchange a set of application identifiers, keys, and endpoints with the **Thales delivery team**.

## Send required data to the Thales delivery team

Provide the following information for your **digital wallet application**.

<table><thead><tr><th width="199">Parameter</th><th width="141">Format</th><th>Description</th></tr></thead><tbody><tr><td><p>PreProd</p><p>FCM service account</p></td><td>JSON file</td><td>Enables sending push notifications to your digital wallet application in the <strong>PreProd</strong> environment.</td></tr><tr><td><p>Production</p><p>FCM service account</p></td><td>JSON file</td><td>Enables sending push notifications to your digital wallet application in the <strong>Production Environment</strong>.</td></tr><tr><td>Apple Team ID</td><td>Alphanumeric string</td><td>Your Apple Developer team identifier.</td></tr><tr><td>App ID</td><td>String</td><td>Your application identifier (for example, a bundle identifier).</td></tr></tbody></table>

{% hint style="info" %}
Use **Apple Team ID** and **App ID** to derive the application binding key.

Thales uses this key to bind wallet enrollment requests to your **digital wallet application**.

Only registered digital wallet applications can enroll wallets. See [Enroll wallet](/nfc-wallet-sdk-ios/implement-nfc-wallet/enroll-wallet.md).
{% endhint %}

### Get your application data

#### Get FCM service account

For details on FCM Service account, see the [Firebase Console](https://console.firebase.google.com/).

Then contact the **Thales delivery team** to complete the push notification setup.

{% hint style="info" %}
FCM can deliver push notifications to the same digital wallet application from multiple senders.
{% endhint %}

#### Get Apple Team ID and App ID

Get your **Apple Team ID** and **App ID** from your Apple Developer account and/or Xcode project settings.

## Receive this from the Thales delivery team

Configure the following values in your **digital wallet application** and, if applicable, your backend.

<table><thead><tr><th>Parameter</th><th width="391">Description</th><th>Format</th></tr></thead><tbody><tr><td>PreProd source IP addresses</td><td>IP addresses to allowlist in FCM so the Thales backend can send push notifications to the PreProd environment.</td><td>Comma-separated list of IPv4 or IPv6 addresses</td></tr><tr><td>Production source IP addresses</td><td>IP addresses to allowlist in FCM so the Thales backend can send push notifications to the Production Environment.</td><td>Comma-separated list of IPv4 or IPv6 addresses</td></tr><tr><td>PreProd URLs</td><td>Endpoints to connect to the Thales backend in the PreProd environment.</td><td>String</td></tr><tr><td>Production URLs</td><td>Endpoints to connect to the Thales backend in the Production Environment.</td><td>String</td></tr><tr><td>PreProd card information encryption key</td><td>Key to secure transmission of card information (PAN, CSC, and expiration date) in the PreProd environment.</td><td>Hexadecimal string or PEM certificate</td></tr><tr><td>Production card information encryption key</td><td>Key to secure transmission of card information (PAN, CSC, and expiration date) in the Production Environment.</td><td>Hexadecimal string or PEM certificate</td></tr></tbody></table>
