Integrations connect HaloAgents to the tools your team already uses. They make the AI smarter by feeding it data, give it real actions to take in your stack, and route the right alerts to the right place. Most setups take a few minutes, just sign in to the provider and toggle the modes you want.

​
How Integrations Work

Each integration can do up to three things, and you toggle them per workspace from the integration’s detail page:
  • Ingest pulls data from the integration into Halo (contacts, companies, deals, transcripts, contracts).
  • Actions lets the AI agent run functions in the integration (create a HubSpot deal, file a Linear bug, request a Stripe refund).
  • Notifications sends alerts from Halo into the integration (most commonly Slack).
Sync runs real-time over webhooks when supported, with an hourly cron as a fallback so nothing slips through. Manual sync is a one-click button on every integration’s detail page.

​
Setting Up an Integration

1

Open the integrations marketplace

In the dashboard, go to Integrations in the sidebar (/dashboard/integrations). Filter by the mode chips (Sync, Actions, Notifications) to find what you need.
2

Connect

Click Connect on the integration’s card. OAuth integrations (HubSpot, Slack, Stripe, Linear, Zoom) open the provider’s consent screen. API key integrations (PandaDoc, Fathom, Intercom) show a form where you paste your key.
3

Choose modes

On the integration’s detail page, toggle Ingest, Actions, and Notifications. Defaults are sensible: Ingest and Actions on, Notifications off until you set them up.
4

Pick agent actions (if applicable)

For integrations with Actions mode, enable the specific actions per agent at AI Agents > [Your Agent] > Actions. See Agent Actions.
5

First sync

Hit Sync now to trigger the initial historical pull. The cron then keeps it incremental from there.

​
How sync works

The first connect always triggers a full historical sync. Subsequent crons are incremental.

​
Authentication

If credentials go bad, the integration shows an Auth error banner with a “Reconnect” link. Cron sync is automatically skipped while there’s an auth error.

​
Knowledge contributions

Some integrations contribute to your AI’s knowledge base, the data the agent searches at runtime: What gets ingested can be filtered with Learning Rules. Stripe and Linear don’t contribute to knowledge: Stripe data is relational (used in prompts and segments), and Linear data lives in Linear.

​
Beyond the built-ins: Connectors

If the tool you need isn’t in the marketplace, the Connectors tab lets you plug in any external MCP server: an internal company API, a vendor’s MCP server, or a custom wrapper over your own data. Discovered tools become agent actions just like native integration actions. See Connectors (External MCP Servers).
