ServiceNow® Integration Hub enables you to build reusable integrations with third-party systems and call them from anywhere in the Now Platform. For example, you can request Integration Hub to call external systems using integration APIs from the Action Designer Script step, run the Script step on the ServiceNow® MID Server, and activate protocol steps like REST, SOAP, and PowerShell.

Integration Hub is available as part of Workflow Data Fabric. For more information, see https://www.servicenow.com/products/automation-engine.html.

Workflow Studio is a Now Platform feature that enables you to automate processes within a single instance. Without an Integration Hub subscription, you can use base system actions or steps, including the Script step, to manipulate records, send emails, trigger notifications, and perform operations within the instance. Request Integration Hub to automate and create integrations with external systems from the Workflow Studio interface.

You can preview Integration Hub on a Personal Development Instance (PDI).
