## 1. Overview
GoAllPay provides customers with unified API access to help them implement fast, secure and centralized access payment channels.

## 2. API description

### 2.1 Transaction process 
![image](https://git.allpayx.com/OpenAPI/b2c/raw/master/images/pc_flowsheet.png)

### 2.2 Signature rules 

```html
1. For the request message sent to the GoAllPay system, in which all incoming parameters (except parameter signature) according to the field name of ASCII smallest sequence (dictionary), using the format of the URL key/value pair (key1 = value1 & key2 = value2... ) spliced into a string string1.

2. At the end of string1, the signature Key (assigned at GoAllPay upon access) agreed by both parties is spliced directly (no need to connect with "&"), resulting in a stringSignTemp string, and an encryption on stringSignTemp to get the value of signature (The encryption algorithm is subject to the parameter "signType" value).

3. Example of signing process: 
string1: OsType=IOS&OsVersion=&acqID=99020344&backURL=https://testapi.allpayx.com/test&charSet=UTF-8&detailInfo=W3siZ29vZHNfbmFtZSI6ICJhcHBsZSIsICJxdWFudGl0eSI6ICIyIn1d&frontURL=http://example.com&goodsInfo=apple&logisticsStreet=上海市浦东新区xx路xx号xxx室&merID=merchant_id&merReserve=&orderAmount=1&orderCurrency=CNY&orderNum=20220620171733&paymentSchema=UP&signType=SHA256&tradeFrom=H5&transTime=20220620171733&transType=PURC&userID=user01&userIP=114.91.1.243&version=VER000000005
stringSignTemp: OsType=IOS&OsVersion=&acqID=99020344&backURL=https://testapi.allpayx.com/test&charSet=UTF-8&detailInfo=W3siZ29vZHNfbmFtZSI6ICJhcHBsZSIsICJxdWFudGl0eSI6ICIyIn1d&frontURL=http://example.com&goodsInfo=apple&logisticsStreet=上海市浦东新区xx路xx号xxx室&merID=merchant_id&merReserve=&orderAmount=1&orderCurrency=CNY&orderNum=20220620171733&paymentSchema=UP&signType=SHA256&tradeFrom=H5&transTime=20220620171733&transType=PURC&userID=user01&userIP=114.91.1.243&version=VER000000005key
