# Bulk Import Mailboxes

`POST /mailboxes/bulk-import`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/mailboxes/bulk-import`
- Auth: HTTP bearer

Connect many mailboxes you already own, from CSV. Buys nothing.

202 means ACCEPTED, not imported: the work runs in the background and the
response carries no per-row outcome. Poll `GET /mailboxes` to see what
landed, and expect rows to appear gradually rather than all at once.

Credentials in the CSV are write-only - stored encrypted and never
returned by this or any other endpoint.

## Headers

- `Authorization` string, nullable
- `X-Target-Org-Id` string, nullable

## Request body

- MailboxBulkImportRequest: Import mailboxes from CSV. Credentials in the CSV are write-only.
  - `csv_content` string, required: Raw CSV. Credential columns are stored encrypted and never returned.

## Response `202`

Successful Response

- ApiResponseMailboxDomainPayload
  - `data` MailboxDomainPayload, required: An open envelope for one provider/deliverability result. Open on purpose. These payloads are provider state and advisory reads whose contents grow with the product, and a dropped field reads as "nothing to report" rather than "we did not tell you". Every value passes through ``scrub_vendor_names`` on the way in.
  - `pagination` PaginationMeta
    - `page` integer, required: Current page number (1-indexed)
    - `limit` integer, required: Items per page
    - `total` integer, required: Total number of items
    - `has_next` boolean, required: Whether there are more pages
    - `next_cursor` string, nullable: Opaque cursor for the next page; null when there are no more items. Pass it back as the `cursor` query param to fetch the following page without computing page numbers.
    - `total_available` integer, nullable: Search endpoints only: how many records really match, when known. Can be larger than `total`, which is capped at the 10,000 results that can be paged. For company search this is a distinct-company estimate. Null when unknown; absent outside search.
    - `total_is_lower_bound` boolean, nullable: Search endpoints only: true when more records match than `total` shows (the result set is larger than the 10,000 results that can be paged). Absent outside search.
    - `notes` string[], nullable: Search endpoints only: plain-language notes about the result, e.g. that more records match than can be paged, or that a reversed `between` range was put in order.
