Why I did this

A payment handoff is only part of an integration. The order also needs a trustworthy payment state and a way to handle refunds without leaving the two systems out of step.

Separate test and live tabs sit alongside payment-method and notification controls. Credential values remain masked by the product.

How I did it

I built a standalone FluentCart gateway that creates HitPay payment requests, verifies webhook signatures and rechecks payment status through the API. Merchant-enabled payment methods appear in hosted checkout.

Outcomes

The integration is available in the DASy FluentCart payment settings. Its configuration exposes separate test and live credentials, payment-method controls and webhook guidance, alongside the implemented transaction and refund handling.
