Payment completion




1. Initiate the customer

When the customer chooses to pay with Alipay, your system will need to perform an AUTH request and, if successful, redirect the customer’s browser to the URL returned in the response.


AUTH request

The example request below is for an Alipay AUTH request:

import securetrading

stconfig = securetrading.Config()
stconfig.username = "[email protected]"
stconfig.password = "Password1^"
st = securetrading.Api(stconfig)

auth = {
    "returnurl": "",
    "currencyiso3a": "EUR",
    "paymenttypedescription": "ALIPAY",
    "billinglastname": "Bloggs",
    "requesttypedescriptions": ["AUTH"],
    "sitereference": "test_site12345",
    "accounttypedescription": "ECOM",
    "billingcountryiso2a": "DE",
    "baseamount": "1050",
    "billingfirstname": "Joe",
    "orderreference": "My_Order_123"

strequest = securetrading.Request()
stresponse = st.process(strequest) #stresponse contains the transaction response

if (!($autoload = realpath(__DIR__ . '/../../../autoload.php')) && !($autoload = realpath(__DIR__ . '/../vendor/autoload.php'))) {
  throw new Exception('Composer autoloader file could not be found.');

$configData = array(
    'username' => '[email protected]',
    'password' => 'Password1^'

$requestData = array(
    'currencyiso3a' => 'EUR',
    'requesttypedescriptions' => array('AUTH'),
    'accounttypedescription' => 'ECOM',
    'sitereference' => 'test_site12345',
    'baseamount' => '1050',
    'paymenttypedescription' => 'ALIPAY',
    'returnurl' => '',
    'billingfirstname' => 'Joe',
    'billinglastname' => 'Bloggs',
    'billingcountryiso2a' => 'DE',
    'orderreference' => 'My_Order_123'

$api = Securetradingapi($configData);
$response = $api->process($requestData);

settlestatus Numeric 3 This allows you to determine the status of the payment. Refer to the Handling the response section below for information on how to best interpret this field.
sitereference Alphanumeric including
50 The site reference relates to your individual account which you received on setup. If you do not know your site reference, please contact our Support team.


Handling the response

When handling the AUTH response for Alipay payments, the recommendations outlined in our Best practices still need to be followed, with exception to the handling of the settlestatus field, which is subject to different conditions that are detailed below:

The settlestatus returned in the AUTH response is used to determine the status of the Alipay payment:

Settle status 10
If the settlestatus is “10”, the payment is pending settlement.

  • The funds have not yet been settled into your bank account.
  • The next step is to redirect the customer’s browser to redirecturl to complete the payment.

Funds will not be settled into your account until the customer is redirected to Alipay’s pages, in order to complete the payment. Read on for further information.


  • When there is an update to the settle status of the AUTH, you will receive a URL notification to inform you that the settlestatus has been updated to either “3” or “100”.
  • Further information on the notifications can be found below.

Settle status 3
If the settlestatus is “3”, the payment has been cancelled.

  • The payment has been declined, or has encountered an error.
  • To learn more about why the payment was unsuccessful, you will need to look at the errorcode. e.g. “70000” indicates that the payment was declined. Click here for a full list of error codes.
  • In rare cases, the settlestatus can be updated from “3” to “100” (indicating payment has successfully settled). If this occurs, you will receive another URL notification to inform you. e.g. This can be due to the customer contacting Alipay directly to resolve an issue on their account that was preventing the payment from being processed successfully.


2. Redirect to Alipay

After checking the AUTH response, if the request was successful, you will need to redirect the customer’s browser to the redirecturl returned in the response.

Your system will need to redirect the customer’s browser to the redirecturl, which is a page hosted by Alipay, in order to process the payment. At a later time, providing the customer has successfully completed the required steps on Alipay’s hosted pages, the customer’s browser will be redirected back to the returnurl provided in the AUTH request.

When testing, you will be displayed the sandbox as provided by Alipay. To complete a test transaction, you will need to follow the instructions displayed on screen. Please contact your account manager for test credentials to enter while on the sandbox.



3. Payment completion

Once the customer returns from the Alipay hosted page to the returnurl hosted on your site, we recommend that you display a confirmation message stating the payment was successful.

The settlement process for Alipay differs from the standard process followed with card-based payment methods.


If configured, our system will submit a URL notification to inform you of the authorisation. Following authorisation, funds will be settled at a later time, as determined by Alipay.

The notification may not be sent immediately after processing the AUTH. For this reason, you should display a success or error message to the customer immediately after they return from Alipay’s hosted pages, and not wait for this notification.


In the unlikely event that payment is still pending settlement after 7 days (settlestatus “10”), this will be scheduled for investigation and we will contact you with further information.


Before you begin testing, we recommend that you contact our Support team and request that rules are enabled on your account, which submit URL notifications to your system in the following scenarios:


Configuring the authorisation notification

We recommend including at least the following fields in URL notifications sent on authorisation:

*Please choose your preferred format.


Configuring the settlement notification

We recommend including the following fields in URL notifications sent on settlement:


Check the notification

You will need to check the contents of each notification received and respond accordingly by following the processes outlined in the “URL notifications” section of our Action types page. In particular, you will need to look at the updated settlestatus value:




After processing a payment with Alipay, it is possible to pay the customer back by submitting a REFUND request.

Refunds for Alipay are settled immediately (settlestatus “100”).



The REFUND request and response for Alipay payments follow the same field specification as outlined in our standard REFUND documentation. Click here for further information.
