# Managing Integrations

> Connect, manage, and disconnect your external tools.

## Connecting an integration

**OAuth integrations** (Gmail, HubSpot, Slack, Notion, LinkedIn, GitHub, Calendly):

1. Go to **Settings → Integrations**
2. Find the integration
3. Click **Connect**
4. Authorize in the popup
5. Done — available in your next session

**API key integrations** (Apollo, Stripe, ZeroBounce, Brevo, n8n, Apify, Browserbase):

1. Go to **Settings → Integrations**
2. Find the integration
3. Click **Add API key**
4. Paste your key — it's validated on save
5. Done — available in your next session

## Credential storage

All credentials are encrypted with AES-256 at rest. Decrypted only at session start for injection into MCP server configuration. Keys are never logged or exposed in tool call output.

For OAuth integrations, Ultron requests minimum required scope. You can review what access was granted from your OAuth provider's connected apps page.

## Integration status

Each integration shows one of three statuses:

| Status       | Meaning                                     |
| ------------ | ------------------------------------------- |
| Connected    | Active and ready                            |
| Disconnected | Removed or not yet connected                |
| Expired      | OAuth token needs refresh — click Reconnect |

OAuth tokens refresh automatically in most cases. If a token expires and auto-refresh fails, a banner appears in the next session prompting you to reconnect.

## Disconnecting

Click **Disconnect** on any integration to remove it. The stored token or API key is deleted immediately. The integration becomes unavailable in the next session.
