Notes

• All endpoints use /api/v1/customer as the base path
• Search operations are case-sensitive and use partial matching (LIKE %term%)
• The loan application endpoint is a placeholder that always returns 418 I'm a Teapot
• Customer IDs are strings and must be unique
• Date fields are automatically set by the system using @CreationTimestamp
