SERVICE FALLBACK METHOD AND APPARATUS
Techniques are described for processing international transaction refund. In an example implementation, a system receives a refund request for an international transaction associated with a foreign currency. In response to receiving the refund request, the system retrieves previously stored exchange rate information for the international transaction associated with the refund request. The exchange rate information includes an exchange rate between the foreign currency and a national currency that was in effect when the international transaction was originally processed. Moreover, the national currency amount for the international transaction based on the determined exchange rate information of the foreign currency is calculated. The calculated amount to the national currency based on the exchange rate information is automatically converted, which completes the refund request for the international transaction based on the calculated national currency amount.
1 . A computer-implemented method, comprising:
receiving a refund request for an international transaction;
in response to receiving the refund request, retrieving previously-stored exchange rate information for the international transaction associated with the refund request, wherein the exchange rate information includes an exchange rate between a foreign currency and a national currency that was in effect when the international transaction was originally processed;
calculating a refund amount for the international transaction based on the previously-stored exchange rate information;
processing the refund request for the international transaction based on the calculated refund amount.
2 . The computer-implemented method of claim 1 , wherein the exchange rate between the foreign currency and the national currency is set by an international e-commerce platform or by negotiation between a user and an international merchant.
3 . The computer-implemented method of claim 1 , wherein the refund request is a foreign currency refund request, and calculating the refund amount for the international transaction comprises:
converting a target amount of foreign currency into a corresponding amount of national currency based on the exchange rate information for the international transaction, wherein the target amount is the amount originally processed in a payment request for the international transaction.
4 . The computer-implemented method of claim 1 , wherein the refund request is a national currency refund request, and calculating the refund amount for the international transaction comprises:
converting a target amount of national currency into a corresponding amount of foreign currency based on the exchange rate information for the international transaction, wherein the target amount is the amount originally processed in a payment request for the international transaction.
5 . The computer-implemented method of claim 3 , wherein processing the refund request for the international transaction based on the calculated national currency amount comprises:
deducting the target amount of foreign currency from an account of an international merchant;

the target amount is the amount originally processed in a payment request for the international transaction.
11 . The computer-readable medium of claim 8 , wherein the refund request is a national currency refund request, and calculating the refund amount for the international transaction comprises:
converting a target amount of national currency into a corresponding amount of foreign currency based on the exchange rate information for the international transaction, wherein
the target amount is the amount originally processed in a payment request for the international transaction.
12 . The computer-readable medium of claim 10 , wherein the processing the refund request for the international transaction based on the calculated national currency amount comprises:
deducting the target amount of foreign currency from an account of an international merchant;
transferring the target amount of foreign currency to a predetermined foreign currency fund pool; and
returning the converted amount of national currency corresponding to the target amount of foreign currency by using an intermediate account.
13 . The computer-readable medium of claim 11 , wherein the processing the refund request for the international transaction based on the calculated national currency amount comprises:
deducting the converted amount of foreign currency corresponding to the target amount of national currency from an account of an international merchant;
transferring the converted amount of foreign currency corresponding to the target amount of national currency to a predetermined foreign currency fund pool; and
returning the target amount of national currency by using an intermediate account.
14 . The computer-readable medium of claim 8 , wherein processing the refund request for the international transaction comprises crediting an account specified in the refund request for the refund amount.
15 . A computer-implemented system, comprising:
one or more computers; and
one or more computer memory devices interoperably coupled with the one or more computers and having tangible, non-transitory, machine-readable media storing one or more instructions that, when executed by the one or more computers, perform one or more operations comprising:
receiving a refund request for an international transaction;
in response to receiving the refund request, retrieving previously-stored exchange rate information for the international transaction associated with the refund request, wherein the exchange rate information includes an exchange rate between a foreign currency and a national currency that was in effect when the international transaction was originally processed;
calculating a refund amount for the international transaction based on the previously-stored exchange rate information;
processing the refund request for the international transaction based on the calculated refund amount.
16 . The computer-implemented system of claim 8 , wherein the exchange rate between the foreign currency and the national currency is set by an international e-commerce platform or by negotiation between a user and an international merchant, wherein processing the refund request for the international transaction comprises crediting an account specified in the refund request for the refund amount.
17 . The computer-implemented system of claim 8 , wherein the refund request is a foreign currency refund request, and calculating the refund amount for the international transaction comprises:
