# Gmail Actions
Send, reply, search, and fetch Gmail messages with VoltOps-managed actions—no MIME hand-crafting or
token juggling required.
## Prerequisites
1. Gmail API enabled for your Google project plus either:
- OAuth2 credential with `accessToken` + `refreshToken` + client ID/secret, or
- Service account with domain-wide delegation (client email, private key, and optional delegated
user).
2. A Volt project with API keys (`pk_…`, `sk_…`).
3. Gmail credential inside Volt: **Settings → Integrations → Add Credential → Gmail**, choose OAuth2
or Service Account, paste the values, and save. Volt returns a `cred_xxx` identifier.
4. (Recommended) Environment variables:
```bash
GMAIL_CREDENTIAL_ID=cred_xxx
```
## Available actions
- `gmail.sendEmail` – send mail with text/html bodies, CC/BCC, Reply-To, attachments, or save as a
draft (`draft: true`).
- `gmail.replyToEmail` – reply using `threadId` or `inReplyTo` plus the same fields as send.
- `gmail.searchEmail` – search mailbox by query, sender/recipient, label, category, or timestamp
filters.
- `gmail.getEmail` – fetch a single message by `messageId` (formats: `full`, `minimal`, `raw`,
`metadata`).
- `gmail.getThread` – fetch an entire thread by `threadId`.
## Running Gmail actions from code
```ts
import { VoltOpsClient } from "@voltagent/core";
const voltops = new VoltOpsClient({
publicKey: process.env.VOLTAGENT_PUBLIC_KEY!,
secretKey: process.env.VOLTAGENT_SECRET_KEY!,
});
// Send an email
await voltops.actions.gmail.sendEmail({
credential: { credentialId: process.env.GMAIL_CREDENTIAL_ID! },
to: ["teammate@example.com"],
cc: ["manager@example.com"],
subject: "Incident update",
htmlBody: "<p>All systems nominal.</p>",
textBody: "All systems nominal.",
replyTo: ["noreply@example.com"],
attachments: [
{
filename: "notes.txt",
content: Buffer.from("postmortem draft").toString("base64"),
contentType: "text/plain",
},
],
});
// Reply inside an existing thread
await voltops.actions.gmail.replyToEmail({
credential: { credentialId: process.env.GMAIL_CREDENTIAL_ID! },
to: ["teammate@example.com"],
subject: "Re: Incident update",
textBody: "Thanks for the quick fix.",
threadId: "188b6c3a3d9a1a2b",
inReplyTo: "<message-id@example.com>",
});
// Search and hydrate results
const search = await voltops.actions.gmail.searchEmail({
credential: { credentialId: process.env.GMAIL_CREDENTIAL_ID! },
query: "from:alerts@example.com after:1719700000",
maxResults: 5,
});
// Fetch a message directly
await voltops.actions.gmail.getEmail({
credential: { credentialId: process.env.GMAIL_CREDENTIAL_ID! },
messageId: "188b6c3a3d9a1a2b",
format: "full",
});
```
## Treat Gmail actions as tools
```ts
import { createTool } from "@voltagent/core";
import { VoltOpsClient } from "@voltagent/core";
import { z } from "zod";
const voltops = new VoltOpsClient({
publicKey: process.env.VOLTAGENT_PUBLIC_KEY!,
secretKey: process.env.VOLTAGENT_SECRET_KEY!,
});
