Wix Headless / Velo API
Exposes Wix platform capabilities — including content management, e-commerce, bookings, and members — as REST APIs and JavaScript SDKs for headless and server-side integrations.
Score Breakdown
⚙ Agent Friendliness
🔒 Security
OAuth 2.0 and API keys over TLS; scopes align to Wix service namespaces. API keys are long-lived and require manual rotation.
⚡ Reliability
Best When
You are building a headless front-end or server-side integration on top of an existing Wix site with commerce, bookings, or CMS data.
Avoid When
You need a fully platform-agnostic commerce or CMS API with no vendor lock-in.
Use Cases
- • Build a headless storefront that reads product and order data from a Wix backend
- • Sync Wix CMS collections with external data sources or CDNs
- • Automate Wix Bookings scheduling — create, update, or cancel appointments programmatically
- • Manage Wix Members and site access programmatically for membership-gated content
- • Trigger custom business logic via Wix Automations when orders or bookings are created
Not For
- • Accessing raw Wix website HTML or page builder elements programmatically
- • High-frequency transactional workloads requiring sub-50ms API latency
- • Migrations away from Wix — API access is tightly coupled to Wix hosting
Interface
Authentication
OAuth 2.0 for third-party app integrations via Wix App Market; API keys for headless/server-side access. Scopes are defined per Wix service (Stores, Bookings, Members, etc.).
Pricing
Headless API access is a distinct product tier; pricing is separate from regular Wix subscriptions.
Agent Metadata
Known Gotchas
- ⚠ API namespaces (Stores, Bookings, Members, etc.) have inconsistent pagination styles and error schemas — agents must handle each namespace separately
- ⚠ Wix Velo (server-side JS) and REST API are separate surfaces with different capabilities; not all features are available in both
- ⚠ Webhook event delivery is not guaranteed exactly-once; agents need idempotent event handlers keyed on event ID
- ⚠ API keys tied to specific Wix sites — multi-site agents must manage separate credentials per site
- ⚠ Some APIs (e.g., CMS collections) have read-only REST access and require Velo/backend code for writes
