Welcome

Join Markt documentation: guides, developer resources, and API reference for sellers and integrators. Join Markt is a multi-vendor commerce platform for digital products. Vendors run independent storefronts on subdomains or custom domains; buyers check out, pay, and receive delivery instantly. These docs cover day-to-day shop setup, developer integrations, and the HTTP APIs your tools can call.
