userInitiatedPay (entry code)Alipay+ → ACQP

The userInitiatedPay API is used when the user initiates a payment request by scanning an entry code in Merchant-presented Mode Payment (Push Mode). Alipay+ calls this API to send the decoding request to the Acquiring Service Provider (ACQP) and then processes the payment according to the response returned by the ACQP.

Note: In the following sections, Mobile Payment Provider (MPP) is also known as Payment Service Provider. For example, the pspId parameter specifies the ID that identifies an MPP.

Structure

A message consists of a header and body. The following sections are focused on the body structure. For the header structure, see:

Note:

1. Set the data type of each parameter (except array) as String. This means that you must use double quotation marks (" ") to enclose the parameter value. Examples:

If the data type of a parameter is Integer and its value is 20, set it as "20".
If the data type of a parameter is Boolean and its value is true, set it as "true".

2. For optional parameters that are not required in your case, you can take one of the following actions:

Exclude the parameters from the request body.
Set the parameter values as null (without the double quotation marks).

Do NOT leave the optional parameters empty by setting their values as ""; otherwise, an error might occur.

Response parameters

result Result object REQUIRED

The result of the business processing, including the result status, result code, and result message. For more information about how to return the result, see How to return the result.

Show child parameters

codeType String

The type of code that the user scans.

In the Merchant-presented Mode Payment Entry Code scenario, the valid value is:

STORE_CODE: indicates an entry code.

Return this parameter if the value of the result.resultCode parameter is SUCCESS, which means that the decoding succeeds.

paymentRequestId String

The unique ID that is assigned by the ACQP to identify a payment order.

Return this parameter if the value of the result.resultCode parameter is SUCCESS, which means that the decoding succeeds.

More information:

Maximum length: 64 characters

paymentFactor PaymentFactor object

Factors that impact payment-related items such as service fee, interchange fee (also known as interpartner fee), and regulatory reporting. This parameter is used to identify the payment scenario.

If the value of the result.resultCode parameter is SUCCESS and the value of the codeType parameter is STORE_CODE, which means that the code is decoded as an entry code, return the following child parameters as follows:

isInStorePayment: set the value to true
isCashierPayment: set the value to true
inStorePaymentScenario: set the value to EntryCode

Show child parameters

merchant Merchant object

The merchant information, including the merchant ID, merchant name, merchant category code, and so on.

Return this parameter if the value of the result.resultCode parameter is SUCCESS and the value of the codeType parameter is STORE_CODE, which means that the code is decoded as an entry code.

Show child parameters

paymentCurrency string

The currency code of the payment currency. The value of this parameter must be an alphabetic code that follows the ISO 4217 standard, for example, "EUR" for Euros.

Return this parameter if the value of the result.resultCode parameter is SUCCESS and the value of the codeType parameter is STORE_CODE, which means that the code is decoded as an entry code.

More information:

Maximum length: 3 characters

minPaymentAmount Amount object

The currency code of the payment currency. The value of this parameter must be an alphabetic code that follows the ISO 4217 standard, for example, "EUR" for Euros.

Return this parameter if the value of the result.resultCode parameter is SUCCESS and the value of the codeType parameter is STORE_CODE, which means that the code is decoded as an entry code.

Show child parameters

maxPaymentAmount Amount object

The maximum payment amount that the ACQP would accept.

Return this parameter if both of the following conditions are met:

The value of the result.resultCode parameter is SUCCESS and the value of the codeType parameter is STORE_CODE, which means that the code is decoded as an entry code.
You have set the maximum payment amount limitation.

Show child parameters

indirectAcquirer IndirectAcquirer object

Information of the Indirect Acquiring Partner.

Return this parameter if both of the following conditions are met:

The value of the result.resultCode parameter is SUCCESS and the value of the codeType parameter is STORE_CODE, which means that the code is decoded as an entry code.
An Indirect Acquiring Partner participates in the payment, for example, when you are acquiring through a special payment network.

Show child parameters

paymentExpiryTime Datetime

The time after which the payment order is expired. If the payment transaction is not completed before the time that is specified for this parameter, Alipay+ informs the MPP to close the order.

Return this parameter if the value of the result.resultCode parameter is SUCCESS and the ACQP wants the payment transaction to be completed before a specific time. The default expiration time is 3 minutes. The returned expiration time must be shorter than the default expiration time; otherwise, the default expiration time takes effect instead of the returned expiration time.

More information:

The value follows the ISO 8601 standard format. For example, "2019-11-27T12:01:01+08:00".

settlementStrategy SettlementStrategy object

The settlement strategy that is applied to the payment order. For example, the currency that the ACQP wants to be settled against.

Return this parameter if the value of the result.resultCode parameter is SUCCESS.

Important: If the settlement currency is different from the payment currency, that is specified on the paymentAmount.currency or paymentCurrency parameter, you must return this parameter correctly; otherwise, you can

Set the value of this parameter to that of the paymentAmount.currency or paymentCurrency parameter.
Set the value of this parameter to null (without double quotation marks).
Exclude this parameter from the response body.

In the latter case, the value of the paymentAmount.currency or paymentCurrency parameter is used as that of the settlementCurrency parameter.
