Why use this reference

A faster way to work with ServiceNow system properties

ServiceNow system properties influence platform behavior across security, user experience, integrations, performance, notifications, knowledge, workflows, and many other areas. This reference helps you quickly understand what a property is for, what its default means, what area it affects, and what related settings may matter before you make a change.

Find properties faster

Search by exact property name, partial match, or topic to quickly locate the setting you need without digging through multiple records, forum threads, or scattered notes.

Understand what matters

Get practical context around default values, affected areas, and likely behavior so you can judge whether a property is only informational, needs review, or may influence important platform behavior.

Review changes with more confidence

Use one place to compare property purpose, related settings, and source references before adjusting instance configuration in development, testing, or production environments.

What you can do here

Built for common ServiceNow property workflows

Whether you are troubleshooting a behavior, reviewing an unfamiliar setting, documenting a configuration, or checking whether a property is relevant for your use case, this page is designed to make ServiceNow sys_properties easier to search, understand, and evaluate.

Troubleshoot platform behavior

Look up properties connected to logging, email, approvals, UI behavior, knowledge, mobile experiences, and other areas when you need to explain or verify instance behavior.

Document configuration decisions

Use the property pages as a practical starting point when you need to explain what a setting does, why it was reviewed, or what teams should consider before changing it.

Explore related settings

Move from one property to related ones to understand the broader configuration space instead of reviewing a single isolated key without context.

Frequently asked questions

Common questions about ServiceNow sys_properties

ServiceNow system properties are used to control or influence platform behavior without changing application code. Depending on the property, they can affect user interface behavior, security controls, notifications, logging, integrations, workflow behavior, and many other areas of the platform.
Some properties are well known and frequently documented, while others are more obscure, more technical, or only appear in specific product areas. In practice, teams often know the behavior they want to review but not the exact property name, which makes search and contextual explanation especially useful.
Before changing a property, it is usually helpful to understand its default behavior, affected area, related settings, and where the change should be tested first. Many properties are low risk, but others can influence broader instance behavior, so reviewing context before changing them is important.
Yes. You can search by exact property name when you already know it, but you can also search by broader terms such as email, approvals, mobile, knowledge, logging, or agent-related topics to discover relevant properties more quickly.
Each property page is designed to provide a practical summary of what the property does, what area it affects, what the default means, when it is typically reviewed, and which related settings or sources may help with further analysis.
It is useful for ServiceNow developers, architects, administrators, consultants, and anyone who needs a faster way to understand sys_properties during implementation, review, troubleshooting, or platform governance work.
