I want to accept cryptocurrency through Payqora ( https://payqora.com/) on my fully bespoke HTML / CSS / JavaScript site. The flow is straightforward—visitors will be making one-time purchases only—but I need the integration to feel completely native to the rest of the site. Alongside wiring up Payqora’s API (checkout widget, callbacks, webhooks or REST endpoints—whatever their latest docs recommend), I also need: • A custom-designed checkout page that matches my brand styles and loads seamlessly within the existing codebase. • Multi-currency support so prices can automatically switch between at least USD, EUR, and the major coins Payqora supports. • A lightweight, back-office transaction report—JSON or CSV export is fine—that pulls key details (TX hash, amount, currency, timestamp, status) for easy reconciliation. Please keep the code clean, commented, and compatible with vanilla JS. Once the integration is in place, a quick sandbox test followed by a live transaction demo will serve as the acceptance criteria.
