Agent pitfalls & tips
- Instance URL is company-specific: {company}.service-now.com.
- Table API is the most common — almost everything is a table.
- sysparm_query uses encoded query format (e.g., priority=1^state=2).
- Free Personal Developer Instance (PDI) available for testing.
- Scripted REST API allows custom endpoints — ask the admin about available ones.
- sysparm_display_value=true returns labels instead of sys_ids.
