How to integrate

1. Prepare Payment Token Request

To prepare a payment token request, refer to the required parameters below.

📘

Please refer: Payment Token API Request

{
    "merchantID": "JT01",
    "invoiceNo": "1523953661",
    "description": "item 1",
    "amount": 1000.00,
    "currencyCode": "SGD",
    "paymentChannel": ["CC"] //Specify which payment option
}

2. Receive Payment Token Response

To receive a payment token response, refer to the sample payment token response below.

📘

Please refer: Payment Token API Response

{
  "webPaymentUrl": "https://sandbox-pgw-ui.2c2p.com/payment/4.3/#/token/kSAops9Zwhos8hSTSeLTUcCrwcnrndJUZanGJy3fBEsXCiYmynwxHvK5h7XPBadJqD0nG7v65t5N2jPVrnwX2jL4nu%2bKKSegjUjERKCyWPg%3d",
  "paymentToken": "kSAops9Zwhos8hSTSeLTUcCrwcnrndJUZanGJy3fBEsXCiYmynwxHvK5h7XPBadJqD0nG7v65t5N2jPVrnwX2jL4nu+KKSegjUjERKCyWPg=",
  "respCode": "0000",
  "respDesc": "Success"
}

3. Validation of Payment Token

Proceed only when the parameter "respCode" is "0000". Otherwise, terminate the payment process. Refer to the Payment Response Code below.

🚧

Please refer : Payment Response Code

4. Redirect to Payment Page

Redirect to payment page via browser. The payment page URL is returned in the Parameter "webPaymentUrl".

5. Receive Payment Response via backend API

📘

Please refer : Payment Response - Backend API

The parameter "backendReturnUrl" that was previously sent via Payment Token Request is the merchant endpoint that will receive the backend notification. If the parameter "backendReturnUrl" is not set, the system will obtain the backend return URL from the merchant profile set in 2C2P's merchant portal by default.

{
  "merchantID": "JT04",
  "invoiceNo": "280520075921",
  "accountNo": "411111XXXXXX1111",
  "amount": "230.87",
  "currencyCode": "THB",
  "tranRef": "2868821",
  "referenceNo": "2785703",
  "approvalCode": "531484",
  "eci": "05",
  "transactionDateTime": "20200528080508",
  "respCode": "0000",
  "respDesc": "Success"
}

6. Receive Payment Response via browser redirection

📘

Please refer : Payment Response - Frontend API

Fill in the parameter "frontendReturnUrl" with the merchant page that you wish to redirect to. If the parameter "frontendReturnUrl" is not set, the system will obtain the front end return url from the merchant profile set in 2C2P's merchant portal by default. Refer to the sample **response** returned below.

{
	"invoiceNo": "280520075921",
	"channelCode": "CC",
	"respCode": "2000",
	"respDesc": "Transaction is completed, please do payment inquiry request for full payment information."
}

The parameter "respCode" specifies the status of the transaction and also indicates what action should be performed next. Refer to the Payment Flow Response Code below.

🚧

Please refer : Payment Flow Response Code

7. Payment Inquiry to retrieve payment information

📘

Please Refer : Payment Inquiry API

For merchants who do not implement "Receive Payment Response via backend API", you are required to call to the Payment Inquiry API to receive the payment response.
