IntegrationHub enables execution of third-party APIs as a part of a flow. These integrations are referred to as

An action is a single operation performed within a spoke, not the entire integration module itself.

A 'spoke' in IntegrationHub is a pre-built or custom application that contains a set of reusable actions, subflows, and flows designed to integrate with a specific third-party system or API. Spokes abstract the complexity of API interactions, allowing users to easily incorporate third-party functionality into their ServiceNow flows.

A connection stores the configuration details like credentials and endpoint URLs for a third-party system, but it is not the integration module itself.

An integration step is a generic term and not the specific ServiceNow terminology for these integration modules in IntegrationHub.
