Alipay CN
Topics covered on this page
Accept online payments from Alipay users through your website using the AlipayCN payment method.
This payment method allows you to gain access to one of China's most popular online payment methods without needing an Alipay account or registering for a Chinese bank account. This guide walks you through the payment flow and details on how to implement.
How to enable
- Supported Countries: Thailand, Singapore
- Minimum API version:
2017-11-02
To enable Alipay (Online), send an email requesting this feature to support@opn.ooo.
Payment flow
Alipay (Online) supports payment on mobile application and website. Customers paying via Alipay (Online) go through an app_redirect payment flow. This means they are redirected from your website or mobile application to Alipay’s secure checkout page where they authorize and confirm the payment. For mobile a customer can use Alipay’s app to complete the payment. For website payment a customer can either scan the QR code using the Alipay's app on their phone, or login into their Alipay account to complete the payment. The following screenshots demonstrate two flows: one by checking out the payment on desktop and another one on mobile.
Using a mobile
The customer chooses the wallet they want to pay with ❶ they are redirected to their wallet app to confirm the payment ❷. The payment details are shown ❸. The customer can choose to be redirected to the merchant's confirmation details page by pressing on Back to merchant ❹.
Using a desktop browser
The customer chooses the wallet they want to pay with ❶ ,after that a QR code will be shown ❷. The customer opens corresponding wallet app then uses the qr scanner ❸. The customer scans the QR code ❹. The customer is shown the summary page before confirming their payment ❺. The payment confirmation slip is shown. The customer can choose to be redirected to the merchant's payment confirmation page ❻. Once you receive a webhook completion event, confirm the payment with the customer ❺.
Implementation
Note: alipay
will be deprecated in favor of alipay_cn
To create a charge using Alipay CN, make the following API requests.
1. Create a new payment source (type
: alipay_cn
) using Omise.js or one of the mobile SDKs (iOS and Android)
1. Create a new charge using the identifier of the source created in Step 1.
1. After receiving the charge completion webhook event, retrieve the charge to verify its status (optional, but recommended).
Use your public key to create the Alipay CN source on the client (a customer's browser or mobile phone). Use your secret key to create the Alipay CN charge on the server.
If both the creation and charge of a source must happen server-side, you can create and charge the source in a single API request using your secret key.
Creating a source
When the customer confirms that they wish to pay with this payment method, create a new source specifying the amount
, currency
, platform_type
, and type
.
Parameter | Type | Description |
---|---|---|
amount |
integer | (required) See Limits |
currency |
string | (required) Currency for source as three-letter ISO 4217 code (SGD for Singapore , THB for Thailand) |
platform_type |
string | (optional) Platform the payer is making payment on, iOS ANDROID or WEB |
type |
string | (required) alipay_cn |
The following examples demonstrate the creation of a new Alipay CN source for S$1500. Replace the omise_public_key
and $OMISE_PUBLIC_KEY
variables with the test public key found on your dashboard.
Using Omise.js, the
type
parameter is supplied as the first argument to thecreateSource
method.
Omise.setPublicKey(omise_public_key);
Omise.createSource('alipay_cn', {
"amount": 150000,
"currency": "SGD",
"platform_type": "WEB"
}, function(statusCode, response) {
console.log(response)
});
For testing, you can create the same request using curl.
curl https://api.omise.co/sources \
-u $OMISE_PUBLIC_KEY: \
-d "amount=150000" \
-d "currency=SGD" \
-d "type=alipay_cn" \
-d "platform_type=WEB"

"charge_status": "unknown",
"receipt_amount": null,
"discounts": [],
"promotion_code": null
}
The id
attribute is the source identifier (begins with src
).
Creating a charge
Create a charge specifying the parameters return_uri
, source
, amount
, and currency
.
return_uri
specifies the location on your website to which the customer should be redirected after completing the payment authorization step.URL must be in HTTPS format.
source
specifies the source identifier.amount
andcurrency
must matchamount
andcurrency
of the source.
Can support both manual and automatic capture.
The following example demonstrates how to create a new charge using curl.
Replace $OMISE_SECRET_KEY
with your test secret key found on your dashboard.
Replace $SOURCE_ID
with the id
of the source.
curl https://api.omise.co/charges \
-u $OMISE_SECRET_KEY: \
-d "amount=150000" \
-d "currency=SGD" \
-d "return_uri=https://example.com/orders/345678/complete" \
-d "source=$SOURCE_ID"

Creating a source and charge
Alternatively, you can create and charge a source in a single API request.
curl https://api.omise.co/charges \
-u $OMISE_SECRET_KEY: \
-d "amount=150000" \
-d "currency=SGD" \
-d "return_uri=https://example.com/orders/345678/complete" \
-d "source[type]=alipay_cn" \
-d "source[platform_type]=WEB"
Completing the charge
At this point, you have created a new charge with its status
set to pending
.
Other possible values for charge status
are successful
, failed
, and expired
.
The following sections detail how to authorize a charge, receive its completion webhook event, and update its status.
Authorizing the charge
Redirect the customer to the location specified in authorize_uri
so that they can authorize the charge.
The merchant can simulate this authorization phase in test mode by visiting authorize_uri
to manually mark the charge as Successful
or Failed
.
After the customer has completed the authorization phase, they will be redirected to the location specified in return_uri
.
Receiving the charge completion event
The best way to be notified about the completion of a charge is using webhook events.
Set up a location on the merchant server to receive webhook events, and add this location as a webhook endpoint on the dashboard.
Checking the charge status
After receiving this event, retrieve the charge using its id
and confirm that its status
matches the status
of the charge contained in the event.
If the value of status
is successful
, you got paid.
If the value of status
is failed
, check the failure_code
and failure_message
in the charge object for an explanation.
Possible failure codes are as follows.
Failure Code | Description |
---|---|
payment_expired |
Payment expired. |
payment_rejected |
Payment rejected by issuer. |
failed_processing |
General payment processing failure. |
invalid_account |
Valid account for payment method not found. |
insufficient_fund |
Insufficient funds in the account or the payment method has reached its limit. |
See the Refunds API documentation for information on how to refund a payment charge.
Alipay payment charges can be voided within the next 00:15(GMT+8) after the charge was created.
