Integrations
Connect your voice agent to the tools you already use.
Connect the apps you already run on, then your agent uses them live on the call: look up the caller, book the appointment, log the result. Over 1,000 apps, most in one click.
On the call
What a connected agent does
A connected app isn't a setting the agent reads. It's an action it takes, live, while the caller is still on the line.
- Booking
Books the appointment. The caller wants a time. The agent reads your Google Calendar, books a free slot, and emails the confirmation from Gmail before they hang up.
- Lookup
Knows who's calling. It matches the number to a Salesforce or HubSpot contact, greets them by name, answers from their history, and logs the call back to the record.
- Handoff
Raises the ticket. When something needs a person, it opens a Zendesk ticket with the transcript and pings the right Slack channel so nobody starts from scratch.
Setup
How connecting works
Connect the app
Open Connections and choose the app. Managed apps connect in one click on the vendor's consent screen; a few ask for an API key on a secure hosted page.
Pick the actions the agent can use
Choose exactly what the agent may do, from read-only look-ups to full read and write. Start with the recommended set and widen it whenever you like.
Test it, then go live
Run the agent in the browser tester to watch it call the live app, then publish. Voice and text agents share the same connection.
Your data stays yours
Connected, not exposed
The agent acts on your behalf without ever holding your credentials. Connections are brokered, scoped, and revocable.
- Scoped
You choose every action. Pick exactly what the agent may do in each app, from read-only look-ups to full read and write. Start narrow and widen it whenever you want.
- OAuth
No passwords in the agent. Managed apps connect through OAuth on the vendor's own consent screen. There's no API key pasted into a prompt for the model to leak.
- Brokered
Tokens never reach the model. Credentials live inside Composio, the connection broker. The agent only ever holds a non-secret reference to the connected account.

FAQ
Common questions
Over 1,000, through Composio. The apps on this page are the ones that matter most for a phone line; the full catalogue is in the app under Connections.
For managed apps, yes: approve the vendor's consent screen once and you're connected, with no API key and no developer. A few apps connect with an API key you paste on a secure hosted page instead, which takes about a minute.
If it's in the Composio catalogue of 1,000+ apps you can still connect it from Connections, even when it isn't featured here. If it has a public API, you can also wire it up as a custom HTTP tool.
Yes. Connect an app once for the workspace and every agent can use it, on voice and on text. You can also connect a separate account to a single agent.
Inside Composio, the connection broker. The agent never sees your tokens or keys; it only receives a non-secret reference to the connected account.
