1. Sign up for 결제선생
Create a payssam account
Sign up at payssam.kr with your business account. Your business
registration (사업자등록) must be complete first. Follow the official
결제선생 회원가입 가이드.
2. Register your business & pass the card-company review
Card companies review each business before it can send payment requests. Submit four photos:- Signboard (간판)
- Entrance (입구)
- Interior (내부)
- Products / items handled (취급품목)
Photo tips
- Shared office / no signboard: substitute equivalent photos (e.g. the building/suite and your workspace).
- Home-based business: include the road-name address sign and your entrance.
- Products: show your product or course page on a laptop screen and photograph that.
3. Connect Paymint to Magic Meal Kits
Update Magic Meal Kits to the latest version
Redeploy your server to the latest version first — see Installation → Upgrading.
Set up the connection
Configure the Paymint connection with your account details. Connection setup and management
is centralized at
make.magicmealkits.com/connections. See
Authentication for the connection fields (MMK mode vs Traditional mode).
There are two onboarding paths:
- General — complete the card-company review above, then connect.
- Magic Meal Kits partner-only — a separate application after Magic Meal Kits signup.
Costs
- Paymint runs on a prepaid balance — top it up from the Magic Meal Kits site whenever you need.
- Sending or resending an invoice 알림톡 costs ₩70 per message.
- Cancel and balance/status lookups are not charged.
- A small overdraft is allowed: sends keep working until your balance falls below about
−₩2,100 (roughly 30 messages past zero), after which payment-sending calls are blocked
with
402“Insufficient balance”. Keep your balance topped up. See the API reference.
Running multiple businesses
- Each business uses its own Payment Only plan — buy one plan per additional business.
- You can register up to 2 accounts per login.
- Apply the correct business to every module. Mixing businesses across a flow fails — e.g. sending an invoice from business A and then cancelling on business B will not work.
