Preliminary Preparation / Test Account Information

This chapter describes some testing information you need to know and to prepare before testing API calls.
Before integrating ECPay’s e-invoice services into your system, we strongly recommend you to do testing at ECPay’s stage environment firstly before you go live. The stage environment is an exact copy of the ECPay’s production environment, which is the real or live mode. Following testing information or credentials are shared at ECPay’s stage, so you do not have to do any extra registration. Every API call will require MerchantID, which is a unique string of 7-digit, with its pair of HashKey and HashIV.
At production (live mode), the MerchantID, HashKey and HashIV is a globally unique ID of your account, so please be sure to keep it properly in order to avoid any risk of information security (i.e. data leakage). Except for the MerchantID, HashKey and HashIV for testing, following table summarizes the account (username), password and Tax ID to sign in ECPay’s dashboard (i.e. ECPay’s dashboard, also at stage).
The dashboard offers a user interface for users who are not developers to operate. It provides such features as managing payments and refunds, configuring your ECPay account, generating transaction reports, searching feature for financial personnel to lookup transaction data or list of e-invoice which have been issued. To sign in the dashboard at stage please see the following table.

Following information are only for testing API integrations at Stage. Do not use it at Production.
When you finish testing and about to go to Production, please replace the MerchantID, HashKey and HashIV with real ones that you apply to ECPay.
If you do not know your real MerchantID, HashKey and HashIV applied to ECPay, please follow the guide in this FAQ to get them.
