I need the Payqora.com payment gateway wired into my custom-built website so customers can complete purchases without leaving my domain. The codebase is entirely bespoke (no WordPress or Shopify framework involved), and I will give you full access to a staging environment as soon as we get started. What I expect from you: • Install and configure the Payqora API keys (I’ll supply or generate them once you tell me what’s required). • Build the secure checkout flow, including tokenisation, callback / webhook handling, and clear error messaging. • Ensure transactions appear correctly in my Payqora dashboard and that order statuses on the site update in real time. • Run end-to-end sandbox tests, then move everything to live. • Hand over concise implementation notes so future updates are straightforward. Acceptance criteria 1. A test transaction succeeds from cart to confirmation page. 2. Failed transactions return an intelligible error without exposing sensitive data. 3. Funds settle and the corresponding order displays the correct payment status in the admin panel. Please be comfortable working with raw PHP, JavaScript, or similar server-side code; once you see the repo you’ll know exactly which language is in play. If account setup steps with Payqora are still outstanding, walk me through them so we can go live without delays.
