wix-vibe-headless
wix/skills
Client-only, dependency-free REST scaffolds for connecting an already-built front end (a vibe-coded app, an HTML/JSX/Vite project, a design-tool export) to a live Wix site over the site's public WIX_CLIENT_ID — the browser talks to Wix directly, no SDK, no backend, no build step. One skill covering every Wix business solution: Stores/eCommerce storefront (products, cart, checkout), Bookings (services, slots, appointments), Blog (posts, categories, tags), Events & Tickets (browse, RSVP, ticketing), Portfolio (collections, projects, galleries), Restaurants (menu, online ordering, reservations), CMS / Wix Data (list, detail, filter, forms, CRUD), Pricing Plans (memberships, subscriptions, checkout), and Members (custom login — email+password, Google/Facebook, and custom SSO — plus account areas and member-gated content). Each vertical ships a copy-as-is REST layer plus wiring instructions. Read-only over the owner's content — never provisions, never mocks data. Triggers: connect my Wix store/shop, build a storefront over Wix, add a cart and checkout, connect Wix Bookings, take appointments/reservations, show my Wix blog, list my Wix events, sell tickets, take RSVPs, build a portfolio from Wix Portfolio, show my restaurant menu / order online / book a table, display my Wix CMS collection, wire a contact form to Wix, sell membership/subscription plans, add member login / sign up, let members log in with Google or Facebook, custom login page, account / profile page, gate content behind login, sign in with SSO/Okta, 'here is my WIX_CLIENT_ID', connect this app to my Wix site over REST. Use this for CLIENT-ONLY REST integration over an existing site; use `wix-headless` instead for SDK + Wix CLI builds, hosting, and one-prompt new-site creation.
