Inside the NMI class, add the following method:

   public function addCustomerVault($creditCard)
   {
       $data = [
           'ccnumber' => $creditCard['cc_number'],
           'ccexp' => $creditCard['exp_date'],
           'cvv' => $creditCard['cvv'],
           'customer_vault' => 'add_customer',
           'security_key' => $this->securityKey,
       ];

       if ($this->production === false) {
           $data['test_mode'] = 'enabled';
       }

       $createVaultCurl = curl_init();
       curl_setopt_array($createVaultCurl, [
           CURLOPT_URL => $this->url,
           CURLOPT_RETURNTRANSFER => true,
           CURLOPT_POST => true,
           CURLOPT_POSTFIELDS => http_build_query($data),
           CURLOPT_SSL_VERIFYHOST => false,
           CURLOPT_SSL_VERIFYPEER => false,
       ]);
       $createVaultResponse = curl_exec($createVaultCurl);
       curl_close($createVaultCurl);

       \Log::info('NMI Vault Response: ' . $createVaultResponse);

       if ($createVaultResponse === false) {
           return [
               'responsetext' => 'error',
               'error' => 'Customer vault creation failed',
           ];
       }

       parse_str($createVaultResponse, $vaultResponseArray);
       return isset($vaultResponseArray['customer_vault_id']) ? $vaultResponseArray['customer_vault_id'] : null;
   }
