# Emails API reference

List, read, reply to and delete email.

Requests go to `https://api.revdoku.com`. Every path starts with `/v1`, for example `https://api.revdoku.com/v1/mailboxes`. Send `Authorization: Bearer $REVDOKU_API_KEY` from your server. Tables use JSON names; where TypeScript differs, a field shows `json_name` / `typescriptName`. Python uses the JSON names.

## List emails

`GET /v1/mailboxes/{mailbox_id}/emails`

Requires mailbox read permission.

Lists received email by default. To poll, list in ascending order, save pagination.next_cursor after every page (including an empty page) and send it next time with the same filters. Listing never marks email read.

| Language | Call |
| --- | --- |
| TypeScript | `client.listEmails({ mailboxId })` |
| Python | `client.list_emails(mailbox_id)` |
| TypeScript, full API | `client.api.listEmails({ mailboxId })` |

| `mailbox_id` / `mailboxId` | string | yes |  |
| `account_id` / `accountId` | string | no | Select another granted account for this request. Omit to use the credential default. In JSON bodies, send account_id as a body field instead. |
| `reason` | string or null | no | Optional purpose for this action. AI agents should explain intentional reads and changes when known; omit when unknown. Do not include secrets, file contents, or transcripts. |
| `limit` | integer | no |  |
| `cursor` | string | no | pagination.next_cursor from the previous page. |
| `order` | string: `asc`, `desc` | no | Arrival order. Use asc to poll. |
| `direction` | string: `received`, `sent`, `all` | no |  |
| `sender` | string | no | Exact sender address, case insensitive. |

| `read` | boolean | no |  |
| `has_attachments` / `hasAttachments` | boolean | no |  |
| `conversation_id` / `conversationId` | string | no | Return the emails of this conversation. |
| `include_storage` / `includeStorage` | boolean | no | Include backing file IDs for file-browser integrations. |

**Examples**

**TypeScript**

```ts
import { Revdoku } from 'revdoku';

const client = new Revdoku();
const savedCursor: string | undefined = undefined; // the cursor you saved after the last page
const { data } = await client.listEmails({ mailboxId: 'bkt_example', order: 'asc', cursor: savedCursor });
for (const email of data.emails) {
  console.log(email.id, email.receivedAt, email.subject);
}
// Save the cursor after every page, also after an empty page.
const nextCursor = data.pagination.nextCursor;
console.log(nextCursor);
```

**Python**

```python

client = Revdoku()
saved_cursor = None  # the cursor you saved after the last page
response = client.list_emails("bkt_example", order="asc", cursor=saved_cursor)
for email in response.data.emails:

| `emails[].subject` | string or null |  |
| `emails[].from_addresses` / `fromAddresses` | array of DecodedEmailAddress | Parsed From authors in header order, retaining multiple authors. Empty when absent/unparseable. Display names are not identity keys. Fields: `address`, `name`. |
| `emails[].to_addresses` / `toAddresses` | array of DecodedEmailAddress | Parsed To recipients in header order, with named groups flattened. Empty when absent/unparseable; not trusted delivery routing. Fields: `address`, `name`. |
| `emails[].cc_addresses` / `ccAddresses` | array of DecodedEmailAddress | Parsed Cc recipients in header order, with named groups flattened. Empty when absent/unparseable. Fields: `address`, `name`. |
| `emails[].reply_to_addresses` / `replyToAddresses` | array of DecodedEmailAddress | Parsed Reply-To addresses in header order. Empty when absent/unparseable. Does not authorize sending a reply. Fields: `address`, `name`. |
| `emails[].message_id` / `messageId` | string or null | Sender Message-ID without angle brackets, preserving case. Null when absent/unparseable/ambiguous; never the Revdoku delivery ID. |
| `emails[].in_reply_to` / `inReplyTo` | array of string | Ordered parent Message-IDs without angle brackets, preserving case. Empty when absent/unparseable; multiple parents are retained. |
| `emails[].references` | array of string | Ordered References IDs without angle brackets, preserving case. Empty when absent/unparseable. |

| `emails[].withheld` | boolean | True means Revdoku hides the email's content from API keys and MCP: the subject, display names, sender address (except its domain), body and attachments. If labels includes the Junk label, the email is junk: skip it. Downloads of the email and its files return EMAIL_WITHHELD, and a person can review it in the dashboard. Otherwise AI labels have not checked it yet: keep its ID and read it again with getEmail / get_email after a few seconds. The read returns 503 EMAIL_LABELING_PENDING with Retry-After until the label is ready (at most about one minute). Do not drop a pending email. |

| `pagination` | Pagination | One page of a list. Request the next page with cursor=next_cursor and the same filters. Cursors are opaque strings: do not build or decode them. |
| `pagination.limit` | integer |  |
| `pagination.has_more` / `hasMore` | boolean | True when another page exists. |
| `pagination.next_cursor` / `nextCursor` | string or null | Cursor for the next page; null on the last page. Email lists always return a cursor so that you can poll for new mail. |

## Send an email

`POST /v1/mailboxes/{mailbox_id}/emails`

Requires mailbox write permission.

Send only to account members, to other mailboxes of the account, or (on paid plans) to addresses that emailed this mailbox and passed sender authentication. The From name is the mailbox title. Set in_reply_to to reply. Delivery is asynchronous: read delivery.status later. After an unknown result, list direction=sent before you send again.
