金鑰的注意事項

Q:金鑰的有效期限

A:MyPay的金鑰有效期限只有一年,如果要延長,請自行至金鑰管理系統延長

Q:金鑰可以在什麼時候延長

A:到期日7天前,都可以延長(不包含第7天),一但超過,系統自動產生新金鑰後,即不可再延長

Q:金鑰即將到期前7天時,系統新發的金鑰是否會於信件中夾帶

A:會

Q:金鑰在到期前何時會發信通知

A:定期發送金鑰到期通知的頻率為:60天/30天/20天,若 貴司皆無動作,則系統會於到期前七天產製新金鑰並發送email到 貴司技術窗口信箱,此時舊的金鑰,因還未過期還可以使用,一旦過期,貴司仍使用舊金鑰則會無法交易

交易結果的告知

Q:交易完成的導頁會有交易結果的參數嗎

A:不論是參數中的success_returl 或 failure_returl或是後臺設定的交易成功、失敗導頁網址,均不會給予交易結果參數

Q:何時會給予交易結果

A:MyPay將在接收上游結果後,會由附錄三這邊的設定,背景主動發動通知商家

Q:當我接到MyPay通知時該做什麼

A:請直接回應8888,如沒有回應,MyPay會通知5次,若5次內均得不到8888,系統會寄發信件給予商家的技術人員以及附錄三而外設定的人員

定期扣款常見問題

Q:電子錢包綁定後可否執行一次性交易+定期定額扣款

A:只能執行一次性交易,無法使用定期扣款

Q:.API發動定期定額扣款,扣款失敗的話,會重扣幾次,多久重扣一次

A:不論是API建檔,還是後臺建檔,預設都是3天後發動重扣,並且只會執行一次,如果要調整,需要至後台調整((參考下圖,如太小請按右鍵可另開分頁放大)),API並無支援調整

Q:.定期定額扣款到一半時,消費者若想換信用卡扣款可以嗎?可透過 API 實現?

A:可以更換卡號,請從後台更改(參考下圖,如太小請按右鍵可另開分頁放大),無法透過API修改,或著發動取消扣款API,從新建立新的

PayPage交易設計概要

安全性設計

所有的付費要求發動都僅能從特約商店的網頁伺服器發出請求,將傳輸的資料以AES加密,再透過HTTPS加密傳輸。交易資料不由消費者端送出,可確保資料不被消費者竄改。所有付費資訊經過MYPAY Link匝道進行轉送處理,特約商店不需要處理消費者的付費流程以及安全控管。

資料驗證

交易參數中有一組由雜湊函式運算出的驗証碼,作為資料驗証用,以確保資料正確性。 大部分交易模式,特約商店以導頁的方式處理付費流程,特約商店只需確保與MYPAY LINK連線正常,即可確保交易安全以及確保資料安全。

系統架構

所有請求與查詢只能透過伺服器發動,由特約商店的網頁伺服器利用伺服端服務程式發動交易,以避免交易資料被消費者竄改或攔截。為確保交易安全,MYPAY Link僅能接受 https connection,注意僅接受TLS1.2以上協定。

MYPAY LINK 目前提供之服務與格式

MYPAY LINK 提供多種交易與應用方式,應用情境如下:

(1)PayPage金流交易請求:透過MYPAY交易頁面作付款動作

(2)交易查詢:查詢金流交易資訊

(3)交易退款:金流交易退款,支援即時退款且未超過退款期限內之支付方式皆可使用此方式發動退款。

(4)信用卡取消授權:信用卡類交易,若使用自行請款模式,交易狀態為授權完成(245)時,則可以發動此信用卡取消授權,用以取消交易,並釋出消費者圈存金額。

(5)信用卡授權請款:信用卡類交易,若使用自行請款模式,交易狀態為授權完成(245)時,則可以發動此信用卡授權請款,用以完成交易。發動只限定一次。可全額或部分請款。

(6)取消定期定額式扣款:取消原有定期扣款訂單,亦可以從管理介面取消。

(7)MYPAY電子錢包綁定:以此API進行消費者信用卡綁定。

(8)取消退款:當該筆退款尚未送到金流服務商時,以取消之前發的退款訂單,若訂單已上傳到金流服務商則無效。

(9)電子發票開立:開立發票可在交易時一併發動請求 或交易成功後獨立發動開立發票。

(10)電子發票查詢:查詢電子發票開立狀態。

(11)特約商店可用支付工具查詢:可查詢特約商店可使用那些支付工具

我們提供介接方式是透過https連線,只接受POST方式傳送交易資料。

信用卡類交易,若使用自行請款模式,交易狀態為授權完成(245)時,則可以發動此信用卡授權請款,用以完成交易。發動只限定一次。可全額或部分請款。

授權請款天數限制

1.請款有天數限制,依照銀行跟代收及非代收的情況,而有所不同,一旦超過請款天數限制,則無法請款,只能重新交易
2.代收付特約商店:一律5天內須要發動請款。
3.非代收付特約商店:依據不同銀行,天數不同,請參考下表,如不再此表內的銀行,代表未支援

銀行名稱 天數
凱基銀行 5天
台新銀行 5天
國泰銀行 5天

MYPAY電子錢包綁定

特店產生一組token專屬會員,以後會員後續交易時,不需要再輸入卡號,加速交易流程與資訊安全。 發動API呼叫信用卡綁定頁面,消費者將信用卡號輸入,系統會綁定貴司電子錢包時,當完成時將畫面導回貴司網站,並會背景通報結果。

電子發票查詢

查詢目前電子發票即時的開立狀態,而交易查詢則包含訂單完整資訊。您可以依您需求作個別查詢。符合查詢規則時,則會回傳相關交易欄位,不符合查詢條件則回傳原查詢欄位。須符合條件才會回傳正確的查詢結果,交易查詢除了提供單筆查詢,也提供一次多筆查詢。
