Top-ups with iPaymu

Top-ups are created and paid from the Top ups section of app.sintaks.dev. The customer portal handles authentication, payment-channel selection, buyer details, idempotency, payment instructions, and status tracking.

QRIS, virtual accounts, convenience stores, cards, paylater, and e-wallets are available through the same portal flow. After iPaymu verifies the payment, the organization balance is credited exactly once.

The portal manages the complete payment flow; customers do not need to call any account-management endpoint directly.
