Why Payment API

Payments for the software you already have

Not every business wants to switch software. Schools, clinics, online stores, ERPs and SaaS products already have systems that work. What they are missing is a simple way to accept instant bank payments and know, automatically, when an order has been paid.

The Star Logics Payment API gives you exactly that. Your system asks for a payment and gets back a dynamic Raast QR for the exact amount. When the customer pays from their bank app, we call your webhook with the payment details, and your system marks the order as paid.

The problemWith Payment API

Customers pay a personal account and send screenshots Each payment uses a dynamic QR tied to one order

Developers check bank statements to confirm payments A webhook tells your server the moment it's paid

Reconciliation is done by hand at month end Every payment carries your order reference

Integrating payments feels heavy A few API calls, with our engineers helping you go live
