Frequently asked questions.
What can I connect to Qashier through the API?
You can connect your existing POS to QashierPay, integrate a third-party payment terminal with QashierPOS, or plug your current system into Qashier Treats for loyalty. Three integration paths, one API.
Do I need to replace my current POS or payment system?
No. The API is built to work alongside what you already have. You keep your existing setup and connect it to Qashier's payment, POS, or loyalty layer without starting from scratch.
Is this suitable for multi-outlet businesses?
Yes. The API scales across multiple outlets, so you do not need to rebuild your stack as you grow. All transaction data consolidates into one dashboard regardless of how many locations you run.
