+# [Azure CLI](#tab/azure-cli)
+
+### Prerequisites
+
+Before you begin, you must have the following:
+
+* The [Azure CLI](/cli/azure/install-azure-cli) version 2.0.67 or later.
+
+* The Azure CLI [extension for Notification Hubs](/cli/azure/ext/notification-hub/notification-hub).
+* The **API Key** for a Google Firebase Cloud Messaging (FCM) project.
+
+### Set up push notifications for Google Firebase Cloud Messaging (FCM)
+
+1. Use the [az notification-hub credential gcm update](/cli/azure/ext/notification-hub/notification-hub/credential/gcm#ext-notification-hub-az-notification-hub-credential-gcm-update) command to add your Google API Key to your notification hub.
+
+   ```azurecli
+   az notification-hub credential gcm update --resource-group spnhubrg --namespace-name spnhubns    --notification-hub-name spfcmtutorial1nhub --google-api-key myKey
+   ```
+
+2. The Android App needs a connection string to connect with the notification hub.  Use the [az notification-hub authorization-rule list](/cli/azure/ext/notification-hub/notification-hub/authorization-rule#ext-notification-hub-az-notification-hub-authorization-rule-list) command to list the available access policies.  Run the [az notification-hub authorization-rule list-keys](/cli/azure/ext/notification-hub/notification-hub/authorization-rule#ext-notification-hub-az-notification-hub-authorization-rule-list-keys) command to get the access policy connection strings.  Specify the **primaryConnectionString** or **secondaryConnectionString** in the `--query` parameter to get the primary connection string directly.
+
+   ```azurecli
+   #list access policies for a notification hub
+   az notification-hub authorization-rule list --resource-group spnhubrg --namespace-name spnhubns --notification-hub-name spfcmtutorial1nhub --output table
+
+   #list keys and connection strings for a notification hub access policy
+   az notification-hub authorization-rule list-keys --resource-group spnhubrg --namespace-name spnhubns --notification-hub-name spfcmtutorial1nhub --name myAccessPolicyName --output json
+
+   #get the primaryConnectionString for an access policy
+   az notification-hub authorization-rule list-keys --resource-group spnhubrg --namespace-name spnhubns --notification-hub-name spfcmtutorial1nhub --name myAccessPolicyName --query primaryConnectionString
+   ```
+
+3. Use the [az notification-hub test-send](/cli/azure/ext/notification-hub/notification-hub#ext-notification-hub-az-notification-hub-test-send) command to test sending messages to the Android App.
+
+   ```azurecli
+   #test with message body
+   az notification-hub test-send --resource-group spnhubrg --namespace-name spnhubns --notification-hub-name spfcmtutorial1nhub --notification-format gcm --message "test notification"
+
+   #test with JSON string
+   az notification-hub test-send --resource-group spnhubrg --namespace-name spnhubns --notification-hub-name spfcmtutorial1nhub --notification-format gcm --payload "{\"data\":{\"message\":\"test notification\"}}"
+   ```
+
+> [!NOTE]
+> Get Azure CLI references for other platforms with the [az notification-hub credential](/cli/azure/ext/notification-hub/notification-hub/credential) command.
