Wix Stores Catalog Versioning

Wix Stores has two catalog versions that are NOT backwards compatible :

V3 modules typically have a V3 suffix. Use Wix MCP to search for the specific module you need.

Core Pattern

Always check catalog version before any Stores operation:

import { catalogVersioning, products, productsV3 } from '@wix/stores';

async function getProducts() {
  const { catalogVersion } = await catalogVersioning.getCatalogVersion();

  if (catalogVersion === 'STORES_NOT_INSTALLED') {
    return [];
  }

  if (catalogVersion === 'V3_CATALOG') {
    // Use V3 module
    const result = await productsV3.queryProducts().limit(10).find();
    return result.items;
  }

  // Use V1 module
  const result = await products.queryProducts().limit(10).find();
  return result.items;
}

Required Permissions

Always look up permissions for each API method you use:

1. Search for the method using SearchWixSDKDocumentation
2. Read the full docs with ReadFullDocsArticle to get the required permissions
3. Return the required permissions to the user

Key Rules

• Call getCatalogVersion() at the start of each flow
• Catalog version is permanent per site (won't downgrade from V3 to V1)
• V1 and V3 have different payload structures — field names, nesting, and types differ
• Subscribe to both V1 and V3 webhooks to handle all sites

Finding SDK Details

Use MCP tools to search for version-specific documentation:

• SearchWixSDKDocumentation - Search for methods and permissions
• ReadFullDocsArticle - Read full documentation when needed

Search queries (results show both V1 and V3 namespaces):

• "getCatalogVersion" → permissions and usage
• "createProduct" → productsV3 (V3) and products (V1)
• "queryProducts" → productsV3 (V3) and products (V1)
• "getInventoryItem" → inventoryItemsV3 (V3) and inventory (V1)

Important: After finding the method, use ReadFullDocsArticle to get the full documentation including required permissions. Return them to the user.

API Differences Reference

V1 and V3 have different field structures. For field mapping, see: Catalog V1 to V3 Migration Guide
