Version

API Version

/v1.2

As with all of our products and services, our API is constantly being improved to better suit our customers’ needs. To help our customers track changes, we include versions in our API. We are currently on Version 1.2 (v1.2).

To specify a version, simply add /v1.2 namespace to the base endpoint before the resource namespace.

For example, to use Version 1.2, the full endpoint for the transactions resource would be: https://api.nihaopay.com/v1.2/transactions

Authentication

Sample Request

$ curl https://api.nihaopay.com/v1.2/transactions \
-H "Authorization: Bearer <TOKEN>"

Replace <TOKEN> with your bearer token generated in the TMS. See Authentication for more information.

Each request must be made over HTTPS and authenticated using your merchant credentials. Authentication is handled through the Authorization header with a Bearer token.

You can view your bearer token in TMS by logging in and going to Settings -> Certificate.

If you believe either your merchant ID, secret key, or bearer token have been compromised, please regenerate your secret key in the TMS. Once you have a new secret key, a bearer token will be automatically regenerated. Please allow 15 minutes for the new bearer token to propagate through the system.

API Description

Payment Mode

NihaoPay supports five payment models: SecurePay, CardPay, In-APP payment, Show QRcode and Scan QRcode.

SecurePay

In Securepay, users will be redirected to the payment tunnel and finish rest of payment steps in the official payment page.

APP Payment

In-APP Payment will ask merchants to call the selected payment model while users are checking out.

Show QRcode

Our API will return a QRcode URL containing information merchant requested. Merchants will be able to show this URL on mobiles or PC web browsers, thereby enabling users to scan the QR code and pay.

Scan QRcode

In the Scan QRcode, merchants are able to sacn user's QRcode to finish the transaction.

For the following products, please refer to MuskPay API Documentation

CardPay

In CardPay, we require merchants' websites to have PCI certification. Merchants will collect users' credit card information and send request to API to finish the order.

2.Currency

Currently, NihaoPay supported currencies:

3. RMB Amount

Use this parameter to replace amount if merchants wish to price their product in RMB. NihaoPay will return an amount in merchant’s settlement currency when payment is successful.

4.Reference

5.Vendor

Currently, NihaoPay accepts three vendors are unionpay, alipay, and wechatpay.

7.Terminal

Currently, acceptable values are ONLINE and WAP.

System Reserve

sys_reserve = {"vendor_id":"4200000117201806013734875340"}

8. System Reserved

sys_reserve, NihaoPay system reserved, used for return vendor's transaction id or customer's info. Currently, includes:

Instant Payment Notification

Asynchronous Response

After payment completed, NihaoPay will return a transaction object to ipn_url using the POST method. Whenever possible, transaction data should be recorded from the IPN URL instead of the callback URL.

When executing the IPN notification, please note:

• ipn_url must be accessible on the Internet and can't be intranet address (for example localhost) or intranet IP
• The IPN notification may arrive ahead of browser callback.
• The duplicated IPN notifications.
• NihaoPay returns to ipn_url using the POST method.
• After the program is executed, the IPN page must print “ok” (without quote). If not, NihaoPay server will keep re-sending notification.
• Generally, there will be 8 notifications within 2 hours (Frequency: 0m,1m,2m,4m,8m,20m,30m).
• After the program is executed, there should not be any redirecting operation on the page, for NihaoPay will not recognize an “ok” string; therefore, it would be regarded as an error, and NihaoPay system will just keep sending the notification.

Asynchronous Response message

Sign method

verify_sign = MD5(key1=value1&key2=value2&...&keyn=valuen&MD5(TOKEN))

Verify signature

When the asynchronous notification returns, NihaoPay will do the MD5 signature on the return message. After the merchant receives asynchronous notification, it will verify that the returned information is tampered with by the signature method.

Signature method:

A. The connection method between the critical message pair and the cooperative key message pair is:

• The indication method for a single pair is key = value. If the value corresponding to the key is null, not include the key.
• The connection method for multiple pairs is key1=value1&key2=&key3=value3. Sort pairs in the signature in an ascending order in accordance with key values.
• The connection method of cooperative key messages is key1=value1&key2=&key3=value3&MD5(Token), The token, after MD5 calculation, is connected to the end of the pair.

B. Signature method

verify_sign = MD5(key1=value1&key2=&key3=value3...&keyn=value&MD5(Token))

Note:

• NihaoPay uses UTF-8 as charset.
• Parameters without a value can be excluded from sign;
• The MD5's output is lowercase when comparing signatures, please ignore case.

SecurePay transactions will redirect users to the vendor’s payment page, where users can enter payment information. Upon successful transaction, users will be redirected to the callback URL. These redirects are accomplished through the use of a JavaScript enabled form.

Due to the nature of redirects and users being able to close their browsers before the redirect can happen, an instant payment notification (IPN) URL is used to provide transaction data.

A reference string is also required to keep track of transactions as the Transaction object will not respond directly to the request but rather in the asynchronous call to your IPN URL. When you receive the Transaction object, you will need to match the reference against your records in order to determine which transaction IDs correspond to which requests.

Request

JSON

Synchronous Response

1. HTML format response >The API returns a synchronous message to the merchant. The message is a form that should be displayed in the browser. The form will submit automatically to the vendor's payment portal, redirecting the user to complete the transaction.
2. Response in JSON format >The returned json data returns a form object or url (not both). If the url is returned, the caller can directly redirect to this url after getting the url. If the return is a form object, the caller needs to use the fields in the form object to construct a form form by itself, and write the form form to In the current webpage request, the page will jump to the payment page after submission.

Asynchronous Response

After the successful completion of a securepay, API will return a transaction object to callback_url using the GET method, returns to ipn_url using the POST method.

Transaction IDs can be used to retrieve details, request cancellations, and create refunds.

Whenever possible, transaction data should be recorded from the IPN URL instead of the callback URL.

Errors

Error

{
    "code": 409,
    "label": "64",
    "message": "Refund or capture currency does not match the original transaction currency."
}

When an API request fails, NihaoPay will return an error object.

NihaoPay errors follow conventional HTTP status codes. A 2xx code indicates request success; therefore, you will not see any of these codes in the error object. A 4xx code indicates an error in the information provided. These could be anything from a malformed request, an unauthenticated request, or an unknown endpoint. A 5xx code indicates NihaoPay’s internal server error.

There are certain features that are not yet available but are documented in this API Reference. Requesting those features from the API will result in a 501 error.

Feel free to contact our tech support team at tech_support@nihaopay.com if you encounter errors.
