Using Relay
Relay acts as a connectivity layer between UiPath cloud services and on-premises resources. The sections below describe what each integration enables. Setup steps for each integration live in the respective product guide — follow the links provided.
With Integration Service
Relay enables Integration Service connections to reach on-premises systems — such as internal Jira, SAP, or custom APIs — that are not exposed to the public internet. Once a Relay Group is configured and an endpoint is registered, you can select Private as the connection type when creating a connection in Integration Service.
This also applies to Bring Your Own LLM scenarios where your language model endpoint is hosted on-premises or in a private network. For more details on using Relay with Integration Service, refer to Connections.
Only HTTP-based connections are supported through Relay. Database Hub connections over Relay are not yet supported.
With API Workflows and Agentic Processes
API Workflows and Agentic Processes can call on-premises APIs through Relay without any changes to your network perimeter. Use the Integration Service connection you created with your on-premises endpoint. This will route the calls to your target systems via Relay.
