> [SDK Payment Enums](https://developer.2c2p.com/docs/sdk-classes-payment-enums)

 

## 1. Prepare Payment Token Request

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

> 📘 Payment Token API
>
> Refer to: [Payment Token API](https://developer.2c2p.com/docs/api-payment-token)

```json
{
    "merchantID": "JT04",
    "invoiceNo": "1595219400",
    "description": "2 days 1 night hotel room",
    "amount": 10.0,
    "currencyCode": "THB",
    "nonceStr": "a8092512-b144-41b0-8284-568bb5e9264c",
    "paymentChannel": ["IMBANK"]
}
```

 

## 2. Receive Payment Token Response

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

```java
String paymentToken = "roZG9I1hk/GYjNt+BYPYbxQtKElbZDs9M5cXuEbE+Z0QTr/yUcl1oG7t0AGoOJlBhzeyBtf5mQi1UqGbjC66E85S4m63CfV/awwNbbLbkxsvfgzn0KSv7JzH3gcs/OIL";

## 6. Initiate Transaction Status Inquiry

To retrieve transaction details and status, merchants must initiate the Transaction Status Inquiry API. Refer to the sample code below.
