# Incrementally synchronize one mailbox

`GET /api/email/changes`

## Request

- Base URL: `https://domani.run`
- URL: `https://domani.run/api/email/changes`
- Auth: HTTP bearer

Call without a cursor to capture a baseline before a bounded full snapshot. Then pass `next_cursor` to replay mutations that happened during and after that snapshot. Cursors are opaque, signed, mailbox-bound, and expire after 30 days. Push notifications are only invalidation hints; this journal is the durable recovery source. An entry about a work item made from authentication mail carries its `title` and `ask` redacted for a token without `email:auth_secrets`.

## Query parameters

- `mailbox_id` string, required
- `cursor` string
- `limit` integer

## Response `200`
