RCA J2C Stripe For J2Commerce is a free payment plugin that sends shoppers through Stripe Checkout for J2Commerce orders on Joomla 4, 5, and 6. You paste live and test API keys, optional webhook signing secret, and choose test mode while sandboxing. Payment methods are controlled in your Stripe Dashboard, not by a dozen per-method toggles inside Joomla. No external Stripe PHP SDK ships in the ZIP; the plugin talks to Stripe with server-side session creation appropriate to J2Commerce v6.
