#### Creating a Rule

1. Go to **Address Validation** > **Real-time Validation Rules**
2. Click **Create validation**
3. Configure:
   * **Name:** What the rule does (e.g., "High Value Warning")
   * **Display Message:** What customers see
   * **Alert Type:** Informative (blue), Warning (yellow), or Error (red)
4. Add triggers (minimum 2):
   * **Shipping Country:** is/is not specific countries
   * **Order Total:** equal/greater than/less than amount
5. Set trigger logic:
   * **All must match:** AND logic
   * **Any can match:** OR logic
6. Click **Publish**

**Example rule:**

* Trigger 1: Order total > $500
* Trigger 2: Country is "United States"
