### Stripe Payment Processing
1096

1097
Stripe payment processing with native SDKs for secure credit card tokenization and payments.
1098

1099
```typescript { .api }
1100
/**
1101
 * Stripe card token parameters for creating payment tokens
1102
 */
1103
interface StripeCardTokenParams {
1104
  /** Card number */
1105
  number: string;
1106
  /** Expiry month */
1107
  expMonth: number;
1108
  /** Expiry year */
1109
  expYear: number;
1110
  /** CVC / CVV code */
1111
  cvc?: string;
1112
  /** Cardholder name */
1113
  name?: string;
1114
  /** Address line 1 */
1115
  address_line1?: string;
1116
  /** Address line 2 */
1117
  address_line2?: string;
1118
  /** City */
1119
  address_city?: string;
1120
  /** State / Province */
1121

1122
  /** Country */
1123

**Usage Examples:**
1151

1152
```typescript
1153
import { Stripe, StripeCardTokenParams } from 'ionic-native';
1154

1155
// Initialize Stripe with publishable key
1156
await Stripe.setPublishableKey('pk_test_XXXXXXXXXXXXXXXXXXXXXXXXXX');
1157

1158
// Create payment token from card details
1159
const cardParams: StripeCardTokenParams = {
1160
  number: '4242424242424242',
1161
  expMonth: 12,
1162
  expYear: 2025,
1163
  cvc: '123',
1164
  name: 'John Doe',
1165
  address_line1: '123 Main St',
1166
  address_city: 'San Francisco',
1167
  address_state: 'CA',
1168
  postal_code: '94105',
1169
  address_country: 'US',
1170
  currency: 'usd'
1171
};
1172

1173
try {
1174
  const token = await Stripe.createCardToken(cardParams);
1175
  console.log('Payment token created:', token);
1176
  // Send token to your server for payment processing
1177
} catch (error) {
1178
  console.error('Payment token creation failed:', error);
1179
}
1180
```
