  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "collection": {
    "name": "Updated Category Name",
    "description": "Updated description",
    "visible": true
  }
}'

Add Products to Category

Method 1: Update Product (Add Category ID)

curl -X PATCH "https://www.wixapis.com/stores/v1/products/${PRODUCT_ID}" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "product": {
    "id": "'"${PRODUCT_ID}"'",
    "collectionIds": ["collection-123", "collection-456"]
  }
}'

Method 2: Bulk Assignment (GraphQL)

Use getProductsList to query products, then update multiple products:

# First, get products that should be in this category
curl -X POST "https://www.wixapis.com/_api/wix-ecommerce-graphql-web/api" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "query": "query getProductsList($offset: Int, $limit: Int, $filters: ProductFilters) { catalog { products(offset: $offset, limit: $limit, filters: $filters) { list { id name categoryIds } } } }",
  "variables": {"limit": 100, "offset": 0},
  "operationName": "getProductsList",
  "source": "WixStoresWebClient"
}'

# Then bulk update products to add category
# (Use REST API PATCH in a loop or bulk endpoint)

Get Products by Category

GraphQL with Filters:

curl -X POST "https://www.wixapis.com/_api/wix-ecommerce-graphql-web/api" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "query": "query getProductsList($offset: Int, $limit: Int, $filters: ProductFilters) { catalog { products(offset: $offset, limit: $limit, filters: $filters) { totalCount list { id name price categoryIds } } } }",
  "variables": {
    "limit": 100,
    "offset": 0,
    "filters": {"categoryIds": ["CATEGORY_ID"]}
  },
  "operationName": "getProductsList",
  "source": "WixStoresWebClient"
}' | jq '{
  category: "CATEGORY_NAME",
  totalProducts: .data.catalog.products.totalCount,
  products: [.data.catalog.products.list[] | {id, name, price}]
}'

Count Products in Category

GraphQL: getProductsTotalCount

curl -X POST "https://www.wixapis.com/_api/wix-ecommerce-graphql-web/api" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "query": "query getProductsTotalCount($filters: ProductFilters) { catalog { products(filters: $filters) { totalCount } } }",
  "variables": {
    "filters": {"categoryIds": ["CATEGORY_ID"]}
  },
  "operationName": "getProductsTotalCount",
  "source": "WixStoresWebClient"
}'

Remove Products from Category

Update product and remove category ID from collectionIds:

curl -X PATCH "https://www.wixapis.com/stores/v1/products/${PRODUCT_ID}" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{
  "product": {
    "id": "'"${PRODUCT_ID}"'",
    "collectionIds": []
  }
}'

Delete Category

Endpoint: DELETE https://www.wixapis.com/stores/v1/collections/{id}

curl -X DELETE "https://www.wixapis.com/stores/v1/collections/${COLLECTION_ID}" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}"

Note: Deleting a category does NOT delete the products, only the category assignment.

AI-Powered Product Categorization

Category Matching Algorithm

For each product, analyze:

1. Product name - Extract keywords
2. Product description - Identify product type
3. Existing tags - Match with category names
4. Product type - Physical/digital/service
5. Price range - Category price patterns

Example Matching Logic

// Pseudo-code for AI category matching
function matchProductToCategory(product, categories) {
  const productKeywords = extractKeywords(product.name + ' ' + product.description);

  const scores = categories.map(category => {
    const categoryKeywords = extractKeywords(category.name + ' ' + category.description);
    const matchScore = calculateSimilarity(productKeywords, categoryKeywords);

    return {
      categoryId: category.id,
      categoryName: category.name,
      score: matchScore,
      confidence: matchScore > 0.7 ? 'high' : matchScore > 0.4 ? 'medium' : 'low'
    };
  });

  return scores.sort((a, b) => b.score - a.score)[0];
}

Category Keyword Patterns

Clothing: shirt, dress, pants, jacket, shoes, apparel, fashion, wear Electronics: phone, computer, gadget, tech, device, electronic Home & Living: furniture, decor, kitchen, bedding, home Beauty: skincare, makeup, cosmetic, beauty, fragrance Food & Beverage: food, drink, snack, beverage, organic Sports & Fitness: fitness, sports, exercise, gym, outdoor Books & Media: book, ebook, audiobook, media, magazine Toys & Games: toy, game, puzzle, kids, children

Bulk Category Assignment

Assign Multiple Products to One Category

# Get all products
products=$(curl -s -X POST "https://www.wixapis.com/stores/v1/products/query" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{"query": {"paging": {"limit": 100}}}')

# Loop and assign
for product_id in $(echo "$products" | jq -r '.products[].id'); do
  curl -s -X PATCH "https://www.wixapis.com/stores/v1/products/${product_id}" \
    -H "Authorization: ${API_KEY}" \
    -H "wix-site-id: ${SITE_ID}" \
    -H "Content-Type: application/json" \
    -d '{
    "product": {
      "id": "'"${product_id}"'",
      "collectionIds": ["TARGET_CATEGORY_ID"]
    }
  }' > /dev/null

  echo "✅ Added product ${product_id} to category"
  sleep 0.2  # Rate limiting
done

Best Practices

1. Category Naming: Clear, specific names (avoid "Other", "Misc")
2. Category Hierarchy: Use parent categories for organization
3. Product Limits: Keep categories under 100 products for performance
4. Visibility: Set new categories to invisible until fully configured
5. SEO: Add descriptions to categories for better search ranking
6. Multiple Categories: Products can belong to multiple categories
