1 Background
Alipay is now focusing on the concept of development platform, with open platform for developers and merchant platform for non-developers. (very similar to wechat) I suggest that you first go to understand the introduction and functions of the two platforms.

Click here to jump to alipay merchant platform
When we click on the payment document, we’ll see all redirects to the open platform. Therefore, Alipay will gradually open the ability to pay in the open platform. Several payment methods have been updated.
2 Payment Method
The payment way that pays treasure has the following kinds altogether
- Pay in person – scan code payment – bar code payment
- App to pay
- Mobile website payment
- Payment on arrival
We can take a look at the payment document entry of open platform and merchant platform respectively:
Open platform document entry
Merchant platform document entry
Click on it and browse it. Several payment methods are still in transition from merchant platform to open platform. (It’s a little confusing.)
- Face to face payment can only be used after applying for an AppId on the open platform (should be released after the open platform).
- Instant payment is not integrated into the open platform, it can only be called through the old interface, and the entrance is still only in the merchant platform.
- App payment and mobile website payment are the new version and the old version of the points.
The new version of the document is shown below:
The document of an earlier version is as follows:
What are the differences between the old version and the new version of the two updated payment methods
3. Payment difference between new and old versions
Completing a complete payment involves the following process:
- Access to pay
- Create transaction information
- The client initiates the payment
- Receiving information asynchronously
- Query transactions
- A refund
The old version of the process was explained in detail in the previous series of articles, but the new version of the process is described below.
3.1 Access Payment
In the development platform, you need to create applications. Specific creation and configuration guide the official document is as follows: openhome.alipay.com/platform/cu…
After creating and configuring the application, you need to open the payment service. Enter the specific application – Function Information – Application function
After the application is approved, payment can be made through the interface.
3.2 Create transaction payment
The new version of transaction creation payment mainly changes the partner into appID, that is to say, each payment not only belongs to alipay account, but also belongs to the specific application. The other is some fine tuning of parameters and interface name replacement. I won’t repeat it here.
PS: Alipay provides the SDK of the server side. It is recommended to refer to it directly, without the need for stitching parameters and requests
3.3 Client Initiates payment
It is recommended to download the latest client and replace it with the latest method. After replacement, it is found to be compatible with the parameters generated by the interface of the earlier version.
My Github client has also been updated:
- The Android client: PayAndroid
- The iOS side: PayiOS
3.4 Receiving Information Asynchronously
The new version of the documentation is more explicit about receiving information asynchronously and processing descriptions. Compared with the previous version, there are modifications to the parameters, such as the parameter name of the amount. Also added a reminder of how to handle authentication information:
3.5 refund
In my opinion, the most convenient way to update the interface is refund. The old version of the refund process looked like this:
PS: the refund flow chart of Ping++ is stolen here. Official Refund Document
That is to say, you need to use the interface to initiate a refund request, and then it will return to you an address, you need to open this address to enter the alipay cashier to enter the payment password to refund.
It’s safer, but it’s too much trouble. Each refund must be confirmed manually.
But!!! When you pay to update to use the new interface, you will find that there is a refund interface
This means that when called, synchronization can return the refund result. I don’t know how many… Greatly reduce the amount of development and Bug rate of refund verification. (The old version of the refund code is Bug prone)
4 summarizes
To sum up, it is strongly recommended to use the new open platform interface if there are conditions or new access to Alipay payment. Those who have received it also suggest updating the upgrade code. (if the client is compatible) We will continue to pay attention to payment related updates and issues.
