  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" | jq -r '.taxGroups[0].id')

echo "Default tax group: ${DEFAULT_TAX_ID}"

# Get products without tax
products_without_tax=$(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": {"filter": "{\"taxGroupId\": null}", "paging": {"limit": 100}}}')

# Assign tax group to each
echo "$products_without_tax" | jq -r '.products[].id' | while read -r pid; do
  curl -s -X PATCH "https://www.wixapis.com/stores/v1/products/${pid}" \
    -H "Authorization: ${API_KEY}" \
    -H "wix-site-id: ${SITE_ID}" \

    -d "{
    \"product\": {
      \"id\": \"${pid}\",
      \"taxGroupId\": \"${DEFAULT_TAX_ID}\"
    }
  }" > /dev/null

  echo "✅ Assigned tax to product ${pid}"
  sleep 0.2
done

Best Practices

1. Always have a default tax group - Assign to most products
2. Create specific groups for exemptions - Tax-exempt items, reduced rates
3. Regional tax groups - For multi-jurisdiction compliance
4. Update rates annually - Tax rates change, keep groups current
5. Audit regularly - Check for products without tax assignments
6. Document tax rules - Include compliance notes in descriptions

Tax Group Naming Conventions

Good Examples:

• "Standard Sales Tax (8.75%)"
• "EU VAT (20%)"
• "Tax Exempt - Digital Goods"
• "Reduced Rate - Food Items (4%)"

Bad Examples:

• "Tax 1"
• "Group A"
• "Default"
