Connect Synerise with Google Wallet to let your customers add [wallet passes](/docs/campaign/wallet-passes) to Google Wallet.

## Requirements

Obtain the following information from Google Cloud Console and the Google Pay & Wallet Console:

| Value | What is it? | Where to find it? |
| --- | --- | --- |
| Issuer ID | The unique identifier assigned to your Google Wallet issuer account. | In the Google Pay & Wallet Console. |
| Issuer name | The name configured for your Google Wallet issuer account. | In the Google Pay & Wallet Console. |
| Service account JSON key | The JSON key file of the service account Synerise uses to authenticate requests to the Google Wallet API. | Generated for the service account in Google Cloud Console. |

Instead of connecting your own Google Wallet credentials, you can choose to use Synerise managed credentials when enabling the integration - see step 6 in [Enabling Google Wallet in Synerise](#enabling-google-wallet-in-synerise). In that case, you don't need to collect the values above.

## Collecting integration parameters from Google Cloud

1. Go to [Google Cloud Console](https://console.cloud.google.com/).
2. Select an existing project, or create a new one.
3. In the **IAM & Admin** section, create a service account.
4. Generate a JSON key for the service account, and save the downloaded file—you'll upload it to Synerise as the **service account JSON key**.
5. Go to the Google Wallet API and configure your issuer account.
6. In the Google Pay & Wallet Console, copy the **Issuer ID** and **Issuer name** of your issuer account.

## Enabling Google Wallet in Synerise

1. [Collect the integration parameters from Google Cloud](#collecting-integration-parameters-from-google-cloud).
2. Go to <img src="/api/docs/image/ad5911f3e3e1b87d3cda4bbfa051e6606d9bbc87/icons/settings-icon.svg" alt="Settings icon" class="icon">**Settings > Apps & Services**.
3. In the list of integrations, click **Google Wallet**.
4. Click **New connection**.  
    **Result**: A configuration form opens.

5. In the **Connection name** field, enter a name to identify the connection in Synerise.
6. Under **Authentication method**, choose how Synerise should authenticate requests to Google Wallet:
    - **Use my Google Wallet account** - connect using the credentials you collected above.
    - **Use Synerise managed credentials** - switch the **Enable integration using Synerise credentials** toggle on. Synerise configures and manages the credentials required to access Google Wallet, so no additional setup is required. Skip the remaining steps below.

    
      <div class="admonition admonition-tip"><div class="admonition-icon"><svg xmlns="http://www.w3.org/2000/svg" fill="none" viewBox="0 0 24 24" stroke="currentColor" stroke-width="2.5"><path stroke-linecap="round" stroke-linejoin="round" d="M9.663 17h4.673M12 3v1m6.364 1.636l-.707.707M21 12h-1M4 12H3m3.343-5.657l-.707-.707m2.828 9.9a5 5 0 117.072 0l-.548.547A3.374 3.374 0 0014 18.469V19a2 2 0 11-4 0v-.531c0-.895-.356-1.754-.988-2.386l-.548-.547z" /></svg></div><div class="admonition-body"><div class="admonition-content">

      Use **Synerise managed credentials** for the fastest setup, for example for a proof of concept:
      - Practically instant onboarding.
      - No need to create a Google Wallet Business account.
      - No credentials for you to manage.
      - Lower risk of misconfiguration.

      Use **your own Google Wallet account** if you need full control:
      - Full independence from Synerise's shared issuer.
      - Your own Google Wallet issuer account.
      - You manage access to the credentials on your side.

      </div></div></div>

7. If you selected **Use my Google Wallet account**, under **Google Wallet issuer**:
    1. In the **Issuer ID** field, enter the issuer ID you copied from the Google Pay & Wallet Console.
    2. In the **Issuer name** field, enter the issuer name you copied from the Google Pay & Wallet Console.
    3. Upload the service account JSON key file you generated in Google Cloud Console.
8. Click **Apply**.  
    **Result**: The connection with Google Wallet is created and ready to use as the **Google credential ID** when [configuring a wallet pass's credentials](/docs/campaign/wallet-passes/creating-wallet-passes#configuring-credentials).
