UiPath Integration Service is a feature that enables you to integrate UI and API automation in a unified way. The three main components of UiPath Integration Service are:

Connectors: These are pre-built or custom components that provide access to various applications or systems through their APIs. You can use connectors to perform actions or retrieve data from different sources, such as Salesforce, Slack, Google Sheets, etc. (UiPath Integration Service documentation1)

Connections: These are configurations that store the authentication and connection details for each connector. You can create and manage connections in the UiPath Automation Cloud and share them across different folders and processes. (UiPath Integration Service documentation2)

Triggers: These are rules that define when and how to start a process in Orchestrator based on events from connectors. You can configure triggers to react to data changes, insertions, deletions, or custom events in the connected applications or systems. (UiPath Integration Service documentation3)
