Complete Tax Setup Workflow

Step 1: Check Active Tax Calculator

calculators=$(curl -s -X GET "https://www.wixapis.com/billing/v1/list-tax-calculators" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}")

active_calculator=$(echo "$calculators" | jq -r '.calculators[] | select(.active == true) | .name')
calc_type=$(echo "$calculators" | jq -r '.calculators[] | select(.active == true) | .type')

echo "Active Tax Calculator: ${active_calculator} (${calc_type})"

Step 2: Query Tax Groups

tax_groups=$(curl -s -X POST "https://www.wixapis.com/billing/v1/tax-groups/query" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{"query": {}}')

echo "$tax_groups" | jq '[.taxGroups[] | {id, name, rate, default}]'

Step 3: Get Default Tax Group

default_groups=$(curl -s -X GET "https://www.wixapis.com/billing/v1/tax-groups/default-tax-groups" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}")

DEFAULT_TAX_ID=$(echo "$default_groups" | jq -r '.taxGroups[0].id')
echo "Default tax group ID: ${DEFAULT_TAX_ID}"

Step 4: Query Tax Regions

regions=$(curl -s -X POST "https://www.wixapis.com/billing/v1/tax-regions/query" \
  -H "Authorization: ${API_KEY}" \
  -H "wix-site-id: ${SITE_ID}" \
  -H "Content-Type: application/json" \
  -d '{"query": {}}')

echo "$regions" | jq '[.taxRegions[] | {id, name, code, country, rate}]'

Step 5: Assign Tax to Unconfigured Products

# Find products without tax
products_no_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 default tax to all
echo "$products_no_tax" | jq -r '.products[].id' | while read -r pid; do
  curl -s -X PATCH "https://www.wixapis.com/stores/v1/products/${pid}" \
    -H "Authorization: ${API_KEY}" \
    -H "wix-site-id: ${SITE_ID}" \
    -H "Content-Type: application/json" \
    -d "{\"product\": {\"id\": \"${pid}\", \"taxGroupId\": \"${DEFAULT_TAX_ID}\"}}" > /dev/null
  echo "✅ Assigned tax to product ${pid}"
  sleep 0.2
done

Best Practices

1. Use /billing/v1/ endpoints - These are what the UI uses
2. Always query tax groups before creating products
3. Use default tax group for most products
4. Create specific groups for exemptions or special rates
5. Regional compliance - Set up appropriate tax for each jurisdiction
6. Audit regularly - Check for products without tax assignments
