Use ServiceNow APIs to change functionalities and add features on the ServiceNow AI Platform.

Client

Use client-side JavaScript APIs to control how the ServiceNow AI Platform functions and displays within the web browser. Client-side APIs provide common functionality that you can add to your instance by calling the APIs from client-side scripts such as client scripts and UI policy scripts.

Common use cases:
  • Use the GlideAjax API to call server-side code from a client script.
  • Use the GlideForm API to customize forms.

Client mobile

Cabrillo JS is a client-side JavaScript API for accessing capabilities inside ServiceNow AI Platform native mobile applications. Cabrillo JS provides methods to use native device capabilities, native mobile UI, and other ServiceNow AI Platform mobile functionality.

UI Builder

Use UI Builder APIs when developing client scripts in the UI Builder. Client scripts are executed in response to something happening on a page, such as:
  • User interaction events/actions, such as a button click.
  • Lifecycle events, such as a data broker execution started.

Server

Use server-side JavaScript APIs to change the functionality of existing applications or to build new applications. Server-side APIs provide common functionality that you can add to your instance by calling the APIs from server-side scripts such as business rules and script includes. Scoped APIs are intended for use with scoped applications, and global APIs are intended for use with applications in the global scope. New applications are typically scoped. Applications in the global scope are typically legacy applications.

Common use cases:
  • Use the GlideRecord or GlideQuery APIs to perform create, read, update, and delete operations on record data from server-side scripts.
  • Use the GlideSystem API to access information about the instance or the current user session and to write informational or error messages.
  • Use FlowAPI methods to trigger flows, subflows, and actions from server-side scripts.

REST

Use REST APIs to access and update data on the ServiceNow AI Platform. You can discover these APIs from within your instance by using the REST API Explorer. If you don't find an API that meets your needs, you can create custom REST APIs using the Scripted REST API feature. ServiceNow REST APIs support Basic Authentication and OAuth 2.0 to authenticate requests.

Common use cases:
  • Use the Attachment API to upload and query file attachments.
  • Use the Email API to send and receive email messages.
  • Use the Table API to create, read, update, and delete records in a table.
