What problem does it solve? Wix Stores has two catalog versions (V1 and V3) that are not backwards compatible, with different modules, payload structures, and field names. This Skill ensures your integration always calls the correct SDK module by checking the site's catalog version before any products, inventory, orders, or collections operation. ## Core Features & Use Cases - Catalog Version Detection: Call catalogVersioning.getCatalogVersion() at the start of every flow to determine whether a site uses V1_CATALOG, V3_CATALOG, or has Stores not installed. - Version-Aware SDK Routing: Route operations to productsV3/inventoryItemsV3 for V3 sites or products/inventory for V1 sites, handling their different payload structures. - Permissions Lookup: Use Wix MCP tools (SearchWixRESTDocumentation, ReadFullDocsArticle) to find required permissions for each API method and return them to the user. - Use Case: When building a Wix app that queries store products, first check the catalog version, then run productsV3.queryProducts() or products.queryProducts() accordingly, and subscribe to both V1 and V3 webhooks to support all sites. ## Quick Start Ask the AI to build a Wix Stores integration that checks the catalog version and queries products using the correct V1 or V3 SDK module.
