# Get the bill inbox

`GET /v2/bills/inbox`

## Request

- Base URL: `https://api.slash.com`
- URL: `https://api.slash.com/v2/bills/inbox`
- Auth: API key in header `X-API-Key`

Get the legal entity's accounts payable email address and the senders allowed to email it. Invoices sent there become draft bills.

## Response `200`

The inbox.

- BillInbox: The legal entity's accounts-payable email inbox. Invoices emailed to `address` are parsed into draft bills with `source: email`.
  - `address` string, email: The address to forward invoices to. Absent only for a legal entity that has not finished onboarding.
  - `authorizedSenders` BillInboxSender[]: Senders allowlisted for the inbox, oldest first. Emails from users of the legal entity, addresses on its company domain and known vendors' domains are accepted without an entry here.
    - `id` string, required: Sender id with the `ais_` prefix. Remove the sender with `DELETE /v2/bills/inbox/senders/{senderId}`.
    - `type` 'email' | 'domain', required: `email` matches one address exactly; `domain` matches every address at that domain.
    - `value` string, required: The lowercased address or bare domain.
    - `createdAt` string, date-time, required: When the sender was allowlisted.

## Other responses

- `400`: - `invalid_request (request shape)` — The body, query, or headers failed validation, or a required header is missing. `details` has one entry per failing location, keyed by JSON pointer or header name.
- `401`: - `unauthorized` — API key authentication is missing or invalid.
- `403`: - `forbidden (legal entity)` — The credential is not permitted to act for the selected legal entity. - `not_available` — Public API v2 is not yet available. Use [Public API v1](https://docs.slash.com/introduction) in the meantime. - `user_api_key_required` — The API key is scoped to a legal entity rather than a user. Every v2 request needs a user API key, created under Settings → API keys in the Slash dashboard, together with the `x-legal-entity` header.
- `404`: - `not_found` — No resource matches the identifier. When the identifier is a field of the request, `details` names that `field` and the `id` it received.
- `429`: The request exceeded the applicable rate limit. The response body is plain text, not the error object; clients must not depend on its wording.
- `500`: - `internal` — Slash could not complete the request. Quote `referenceId` when contacting Slash support.
