Payco integration questions
1. Does PAYCO support refunds?
- if yes, is there a time limit (e.g. 1 year?)
- if yes, is there a max/min amount for refund?
2. Does PAYCO support cancel?
2. for PAYCO user experience is it similar to Naverpay? Where regardless of the user's terminal type, it will all be required for user to input their login credentials on a H5 web/wap browser? (what I understand is that Payco doesn't have an APP)
3. What is the timeout/payment expiry period after creating a payment (or after user redirects to Payco website)?
- is it 20 minutes?
4. Can help confirm the following values are correct?
Channel parameters --- Channel enumeration value
method --- CARD
flowMode --- DIRECT
easyPay --- PAYCO

As Korea PG perspective,
refund and cancel goes through same procedure.
1. Yes.
1-2. Normally we are asking merchant to perform the refund within 1 year.
1-3. Max - transaction amount, No Min amount
2. Yes.
2. Payco has its own app.
3. Payment session (Authentication) - 20 mins
4. Yes, these are correct.
hi @유부장 as Payco has its own app, are you able to share the user experience video/screenshots for
- mobile;
- desktop;
- mobile browser?

@Ayaan이안 hello there, can i request for a payco SANDBOX payment account (handphone number/password) to make payment?
is there a standard one used for testing?

ok noted, in that case do you have kakaopay、tosspay、naverpay sandbox credentials for testing?
currently when we send in these for naverpay, kkp, tosspay, we are all getting this page (i have shared our postman request for payco), currently we are only changing the easypay parameter to each wallet name. is this correct?
@Ayaan이안 we are using API integration mode: our expectation is that we should get a URL with the wallets redirection URL and we can let user jump to the wallet directly.
Yes we are using API method, thank you very much.
noted we will remove and test again
