Turn on the LINE Pay deals map
Help customers find your shop on the LINE Pay deals map (好康地圖).

- Under 我的門市/分店 (My stores), switch 顯示於好康地圖 (Show on deals map) to green.
- Tap 編輯 (Edit) and confirm the store phone number and address.
- Add business hours for every day of the week, or the form cannot be saved. For closed days, drag the time to 已結束營業 (Closed).

- Tap 完成 (Done) to save.
Check payments and refunds
Every transaction can be checked in the Partner app.
After a customer pays, confirm the payment under transaction search (交易查詢) in the Partner app.
Accepted payment methods
- Accepted: credit cards, LINE Points
- Not accepted: iPASS (一卡通)
How to refund
- Open the transaction and scroll down to find the cancel option. You can cancel part or all of the amount.
- Cancellations cannot be undone, so check the amount first.
- Before refunding, confirm the last three digits of the customer's phone number.
- Only payments from the last 60 days can be refunded. Older payments cannot be refunded.
Check payout records
Review fees, payout account, and expected payout dates.
Tap the 撥款紀錄 (Payout records) tab at the bottom of the app to see each expected payout date and amount. Expand 手續費及撥款帳戶資訊 (Fees and payout account) at the top to see how fees are calculated and which account receives payouts. Tap 編輯 (Edit) to change the payout account.
(Optional) Web Merchant Center settings
Link your LINE Official Account and a mobile invoice barcode.
These two settings are in the web version of LINE Pay Merchant Center. Sign in with your Store ID and password:
Open LINE Pay Merchant CenterA. Link your LINE Official Account (LINE@)
- Go to 管理基本資訊 > LINE@/官方帳號管理 (Basic info > LINE@ / Official Account).
- Enter your full Official Account ID including @, then click 設定 (Set).
- Check the account details in the table, then click 確認 (Confirm).
Customers can then add your Official Account as a friend right after paying with LINE Pay.
B. Link a mobile invoice barcode
- Go to 管理基本資訊 > 其他資訊 (Basic info > Other info).
- Select 手機載具 (Mobile barcode) and enter your barcode.
- Scroll down and click 儲存 (Save).
Each month LINE Pay emails the previous month's fee e-invoice to your registered email. Linking a mobile barcode stores invoices automatically so you are less likely to miss them.
Frequently asked questions
The app signed me out after a long time. What now?
If a LINE account was linked as the store administrator during activation, tap 以管理者 LINE 帳號登入 (Sign in with administrator LINE account) and tap 許可 (Allow). Your LINE app will receive a verification code from LINE Pay Merchant. Enter it in the app and tap 確認 (Confirm).
I forgot my password.
Tap 重設密碼 (Reset password) on the password screen, or use the web reset page. Enter your Store ID and contact email, then follow the email link to set a new password (8–14 characters with upper- and lowercase letters).
I can't find Map info. Why does the deals map matter?
地圖資訊 (Map info) is under 更多 (More) at the bottom right of the app. The deals map is where LINE Pay users find nearby shops that accept LINE Pay. Turn it on and add hours and photos so customers can see you.
A customer wants a refund after more than 60 days.
The Partner app can only refund payments from the last 60 days. For older payments, contact the LINE Pay Merchant Helper directly.
