1.1 Document Overview

This file describes the payment solution provided for the mobile phone payment industry, used for the internally related developing and technical supporting personnel and commercial tenants service technicians. The files introduces the working mode and development process of Tenpay in the aspects of interactive mode, signature, interface and matters needing attention. It can also help the developers to quickly master the developing skills and can be used as the quick-consulting manual for the interface parameters and parameter types.

1.2 Reading objects

This manual is used as reference and inquiry for Tenpay developers and commercial tenants serving technological or business personnel

1.3 Business terms

Terms Examples Description

Commercial tenant No. 1900000109 Account number of air ticket plant is only used for account keeping and allocated with a 10-bit number by Tenant automatically.

Secrete key 9ba2380ad9b2aacb96bca514eda27ac9 To guarantee no falsification of communication, Tenpay and commercial tenants agree 32-bit character string, used for signature “sign”.

Account number jpgyf@qq.com

Tenpay account number can support two formats presently, qq number and email account number.

Amount 100000 Amount, default as RMB, correct to fen, 1000 indicates RMB 10.00

2 Scheme Overview

2.1 Industry background

Among electronic business, merchants, sellers and intermediary service provider are the three links of transaction activities. The sellers select the goods and place an order. After the merchants confirm the order, the buyer pays the price of goods to the merchants through intermediary service provider, during this process, the merchants’ website requires the integration of the payment function of intermediary service provider to make the buyer complete the payment of goods amount. Apart from providing payment interface, as a professional intermediary service provider, Tenpay also provides results inquiry interface and order inquiry interface to help commercial tenants to record the goods payment, so as to make the commercial tenants concentrate on commercial goods service.

The goods payment of commercial tenants shall be settled to the bank account of commercial accounts in the frequency of T0-T7 and charge the handling expenses. This process shall be completed automatically by Tenpay. The commercial tenants do not require the related development work.

2.2 Interface introduction

Interface name Request URL Function description Description of results

Initialization of interface https://wap.tenpay.com/cgi-bin/wappayv2.0/wappay_init.cgi Appoint payment parameters when calling the interface, complete the payment of the seller’s account to the commercial tenant’s account, and adopt the page-skipping interacting mode and backstage notifying interacting mode. Initiate wap request and make interactive verification through token_id.

Payment interface https://wap.tenpay.com/cgi-bin/wappayv2.0/wappay_gate.cgi

Appoint payment parameters when calling the interface, complete the payment of the seller’s account to the commercial tenant’s account, and adopt the page-skipping interacting mode and backstage notifying interacting mode. Results are returned in two ways. One way is to add parameter returning at the back of “callback_url” at the front desk. The other way is to add parameter returning at the back of “callback_url”, requiring backstage “notify_url” response receiving notification.

Order inquiry interface http://wap.tenpay.com/cgi-bin/wapmainv2.0/wm_query_order.cgi Commercial tenants inquire any order at the backstage and adopt the interacting mode of backstage system calling. Return the specific order contents and status according to order number and XML format.

2.3 Business realizing flow

The blue straight arrows indicates system calling. Back straight arrows indicate the page skipping.

Transaction initiation of commercial tenants request: commercial tenants generates the order according to customers’ payment action, including the commercial tenants, commercial ordering No, amount and other payment elements. And submit request for initiation of transaction and obtain token_id.

1) After Tenpay receives the request of transaction initiation of commercial tenants, the system creates Tenpay trading order and generates token_id simultaneously and returns the token_id.

2) Commercial tenants ask for WAP payment: commercial tenants generates WAP payment request according to token_id. Guide users to enter into the Tenpay mobile phone payment center by page skipping method.

3) After users complete payment at Tenpay mobile phone payment center, Tenpay calls “notify_url” to notify the commercial tenants about the transaction results.

4) Commercial tenants returning results: according to the notification of successful deduction of money, complete the logic processing of goods delivery and return the Tenpay processing results.

After Tenpay confirms the completion of transaction and skips back to “callback_url” of the commercial tenants.

2.4 Call back “callback_url”

“callback_url ” shall be WAP page, showing the payment results.

2.5 Notifying “notify_url”

In this notifying interface mode, commercial tenants shall guarantee the stability and reliability of “notify_url”. The “notify_url” completes the payment results information delivered by Tenpay, the information of transacting results shall be delivered to the commercial tenants of “GET”. Tenpay only returns the successfully-paid order.

3 Data format

3.1 GET or POST

Adopt GET or POST protocol of HTTP standard. In order to guarantee the receiver to receive the correct data, if the transmitted parameters have special characters (like “&, =”) requiring URL Encode.

GET or POST is generally used for the request or notification of page skipping interacting mode, request of back system calling mode and the request of backstage notifying mode.

3.2 XML Data format

Adopt standard XML protocol. All parameters only exist in the first node. Multi-node nesting shall not be adopted.

<?xml version="1.0" encoding="gb2312" ?>

<root>

</root>

Generally, returning code “retcode” parameter is arranged. “0” indicates successful calling. “Non-0” indicates failed calling. The results shall not be signed in case of failure, only with “retcode” and returning information “retmsg”.

XML is generally used for the reply of background system calling mode.

3.3 Character string format

Directly take simple character as the data content. They are generally used as the interface feedback of background notifying mode, indicating whether the treatment is successful or not.

Returning results Result description

success Successfully dealt with, “Tenpay” system would not issue following notice after receiving this result.

“fail” or other characters Unsuccessfully dealt with, Tenypay may receive this result or may not receive any result; the system issues another notice through order-supplementing mechanism (referring to Section 6 for details).

4 Digital signature

To guarantee the authenticity and integrity of data during the data delivery process, we need to make digital signature on the data and make signature verification after receiving the signed data.

The digital signature includes two steps. Firstly, splice the original strings to be signed as per certain rules. Then select the specific algorithm and secrete key to calculate the signature results.

Generally, failed results require no signature.

4.1 Original string of signature

No matter request or reply, no matter using “get”, “post” or “xml”, the signed primitive strings are combined as character strings in the following way.

1. Except “sign” field, all parameters shall use the “QueryString” format after following the order of ascii codes of field from small value to large value (key1=value1&key2=value2…) through splice. Vacant value shall not be transmitted or involve in signature string.

2. All parameters refer to all the non-empty parameters actually appeared in the communication process. Even if the fields without description in the interface, they also require string formation with signature. If no “test” field exists in refunding interface, in case of commercial tenants request or Tenpay replies, and “test” has value, then “test” field shall participate in signed group string.

3. In the signed primitive string, field name and field value shall use the primitive value without URL Encode.

4. The returned reply or notified information from Tenpay may increase parameters due to upgrade. Please pay attention to the conditions when replying this signature.

Example:

Call some interface, the interface has the following field:

“ Partner, total_fee, desc and attach”

In case of actually calling interface, the value of all fields shall be as follows.

partner=1900000109，total_fee=1，desc=a&b，attach=，test=1

The correctly signed primitive strings shall be:

desc=a&b&partner=1900000109&test=1&total_fee=1

The common errors include

desc=a%26b&partner=1900000109&test=1&total_fee=1

desc=a&b&partner=1900000109&total_fee=1

attach=&desc=a&b&partner=1900000109&test=1&total_fee=1

partner=1900000109&total_fee=1&desc=a&b&test=1

Note: the returned result parameter list (6.2.4) in Wap payment interface is very special. The second point is not suitable. That is, all the parameters refer to the parameters describing the interface.

4.2 Signature algorithm

Presently, signature algorithm only supports MD5 signature temporarily.

MD5 signature

MD5 is a kind of abstract generation algorithm. Add the contents of communication secret key of commercial tenants to signature primitive string for MD5 calculation. The formed abstract character string is the signed results. In order to benefiting for comparison, the signed results can be unifiedly converted as capital characters.

Note: when signing, convert character string as byte stream conforming to “input_charset” of the designated character set.

MD5 signature calculation format：

sign = Md5( Original character string &key= commercial tenant secret key) To UpperCase

For example:

Signed original string is : input_charset=GBK&partner=1900000109&total_fee=1

Secret key of commercial tenants : 8db4a013a8b515349c307f1e448ce836

Results of signature:

sign=md5(input_charset=GBK&partner=1900000109&total_fee=1&key=8934e7d15453e97507ef794cf7b0519d)= 8DB4A013A8B515349C307F1E448CE836

5 Order-supplementing mechanism

As for backstage notifying interacting mode, if Tenpay receives the reply no “success” of commercial tenants or overtime, then Tenpay thinks notification fails, Tenpay will regularly issue notification through some strategy (for example, 8 times within 30 minutes), so as to improve the successful rate of notification, but Tenpay can not guarantee the notification can be successful finally.

Due to the conditions of redelivery to the backstage notification, considering that same notification may be issued to commercial tenant system for many times. Commercial tenant system must be capable of processing the repetitive notices correctly.

The recommended practice of Tenpay is to check the status of corresponding business data firstly and judge whether the notice has been processed or not after receiving the notice for processing; if the notice has not been processed, its shall be processed; if it has been processed, it shall return to “successes”, before checking and dealing with the business data, adopt data lock for concurrency control to avoid the data chaos caused by function reentry.
