Relay

Relay lets UiPath cloud services securely reach on-premises HTTP and HTTPS endpoints inside your network — without a VPN, without opening inbound firewall ports, and without changing your network topology.

When you register an on-premises endpoint under a Relay Group, UiPath generates a private Relay URL for it. Cloud services such as Integration Service and API Workflows use that URL to route requests through the UiPath relay infrastructure to a Relay client running inside your network, which forwards each request to the internal target.

Key concepts

TermDescription
Relay GroupA tenant-level container that groups one or more Relay clients and the on-premises endpoints they expose. Each registered endpoint receives a unique Relay URL. Multiple Relay Groups can coexist in a tenant to cover different network segments.
Relay clientA lightweight binary (Windows or Linux) installed on a machine inside your network. It establishes the outbound TLS tunnel to Test Cloud and forwards requests to internal services.
Relay URLA private proxy address generated by UiPath for each registered on-premises endpoint. UiPath cloud services use this URL instead of the actual endpoint address.
On-premises endpointAn endpoint, identified by a hostname (FQDN) or IP address and port, that the Relay client exposes to Test Cloud.
