SmarterServices

All connections are outbound and initiated by the test-taker's browser. No inbound firewall rules are required. Unless noted otherwise, traffic is HTTPS / WSS over TCP 443.

If your firewall/proxy supports wildcards, the shortest working allowlist is:

Proxies: Forward proxies must pass WebSockets (WSS) through without inspection. UDP media should bypass the proxy entirely.

SSL inspection: Exclude <code>*.livekit.cloud</code>, <code>*.twilio.com</code>, <code>*.proctoring.media</code>, and <code>*.upscope.io</code> from TLS inspection; TURN-over-TLS and DTLS will fail otherwise.

SIP ALG / NGFW: Disable SIP ALG; add explicit allow rules for STUN, TURN and DTLS protocols.

Idle timeouts: WebSocket idle timeout ≥ 300 s for signaling hosts.

Screen sharing and webcam are captured locally via Chrome (<code>desktopCapture</code>) and streamed to the media hosts above; no other endpoints are involved.

This list is subject to change as vendors update their infrastructure (LiveKit and Twilio both publish "subject to change" notices). Re-verify against the vendor links above when reviewing.

{appName} in 60 seconds

This prototype demo is aware that you are reading “{title}”. It can point you back to the current article, but a production article-aware Fin contract is still follow-up work.

Prototype article-aware answer

Because you already asked about invitations, this prototype demo can add the follow-up: use the role selector before sending each invite to limit access to the teammate responsibilities.

Prototype role-limiting follow-up

This prototype demo suggests starting with your workspace profile, inviting the team members who need access, and then connecting the integrations you use.

Prototype getting-started answer

In this prototype demo, integrations are configured from workspace settings. Choose the integration, connect the account, and review the enabled permissions.

Prototype integrations answer

In this prototype demo, invite teammates from workspace settings, then choose the access each teammate needs before sending the invitation.

Prototype invite-team answer

This prototype demo does not have a scripted answer for that question yet. Try asking how to invite your team or open a source article. No production Fin API was called.

Prototype answer unavailable

I’ve got this page open. Ask me anything about it and I’ll answer from the docs.
