## 1. Generate Payment Token To prepare a payment token request, refer to the required parameters below. > 📘 Payment Token API > > Refer to: [Payment Token API](doc:api-payment-token) ```java JSON { "merchantID": "JT04", "invoiceNo": "1595219400", "description": "2 days 1 night hotel room", "amount": 10.00, "currencyCode": "THB", "nonceStr": "a8092512-b144-41b0-8284-568bb5e9264c", "paymentChannel": ["ALL"], "loyaltyPoints": [{ "providerID": "DGC", "accountNo": "501105", "redeemAmount": 1.00, "rewards": [{ "quantity": 1.00 }] }] } ```
## 2. Receive Payment Token Response To receive a payment token response, refer to the sample payment token response below. The response will contain the payment token ID which must be passed to the merchant application. ```java Java String paymentToken = "roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL"; ``` ```coffeescript Kotlin val paymentToken = "roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL" ``` ```objectivec NSString *paymentToken = @"roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL"; ``` ```swift let paymentToken: String = "roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL" ``` ```coffeescript Flutter String paymentToken = 'roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL'; ``` ```coffeescript React Native let paymentToken = 'roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL'; ```
## 3. Construct Loyalty Point Info Request To prepare a loyalty point info request, refer to the parameters below. > 📘 Request API Parameters > > Refer to: [Loyalty Point Info API Parameters](doc:sdk-classes-apis-interface#section-loyalty-point-info-request-api) ```java LoyaltyPointInfoRequest *loyaltyPointInfoRequest =[[LoyaltyPointInfoRequest alloc] initWithPaymentToken: paymentToken]; loyaltyPointInfoRequest.providerId = @"DGC"; ``` ```coffeescript Kotlin val loyaltyPointInfoRequest = LoyaltyPointInfoRequest(paymentToken).apply { providerId = "DGC" } ``` ```objectivec PaymentOptionRequest *paymentOptionRequest = [[PaymentOptionRequest alloc] initWithPaymentToken: paymentToken]; ``` ```swift let loyaltyPointInfoRequest: LoyaltyPointInfoRequest = LoyaltyPointInfoRequest(paymentToken: paymentToken) loyaltyPointInfoRequest.providerId = "DGC" ``` ```coffeescript Flutter Map loyaltyPointInfoRequest = { 'paymentToken': paymentToken, 'providerId': 'DGC' }; ``` ```coffeescript React Native let loyaltyPointInfoRequest = { 'paymentToken': paymentToken, 'providerId': 'DGC' }; ```
