ServiceNow Developer

Scoped Application Structure

Por qué: Lets you structure a new application with its own tables, roles and menus so it can be packaged and moved between instances cleanly.

Application Scope & Cross-Scope Access

Por qué: Lets you set the access policies of your app so another team's scripts can read your tables only where you allow, and track who calls what.

GlideRecord API — Query, Insert, Update, Delete

Por qué: Lets you write queries that stay fast on large tables and avoid loops that update thousands of records inside a single transaction.

GlideAggregate

Por qué: Lets you build a dashboard count or a SLA breach total without loading every incident into memory, which keeps the report responsive.

Client Scripts — onLoad, onChange, onSubmit

Por qué: Lets you sequence several client scripts on a complex form and decide which ones belong on the catalog item versus the table form.

g_form & g_user APIs

Por qué: Lets you build dynamic forms where visibility and requirements follow the user's role and prior answers, without duplicating the rule on the server.

Service Portal — Widgets & Pages

Por qué: Lets you assemble a self-service portal page for employees, with its theme and layout, instead of sending them to the standard UI.

Widget Server & Client Controllers

Por qué: Lets you build a custom widget that fetches data on the server, binds it in AngularJS and talks to a neighboring widget on the same page.

REST & SOAP Web Services — Inbound & Outbound

Por qué: Lets you pull data from an external system with an outbound REST message and expose your own endpoint, choosing the right authentication for each.

IntegrationHub & Spokes

Por qué: Lets you connect ServiceNow to Slack or Jira with a spoke instead of custom code, and package a reusable action for other teams.

ACL Scripting & Security Rules

Por qué: Lets you diagnose why a user cannot see a record and write an ACL script that restricts a field to the right condition and roles.

Encryption & Data Protection

Por qué: Lets you decide how sensitive values such as national IDs or tokens are stored, and when column encryption is enough or Edge Encryption is needed.
