workflow. You can create a shipping rate, connect a carrier account, validate
credentials, and return live rates at checkout.

Before you start

• Make sure Shipping Carrier Service Status is active in Settings
  → Shipping Configuration Settings.
• Create at least one Shipping Rule and ensure your Shopify shipping zones
  are synced.
