# Receive bills by email

> Let vendors email invoices straight into Slash.

Every legal entity has an accounts payable email address. Invoices sent to it
are read automatically and become `draft` bills with the files attached.

## Get your inbox address

[Get the bill inbox](/api-reference/bills/inbox/get) returns the address and
any senders you have allowed:

```json theme={null}
{
  "address": "acme@ap.slash.com",
  "authorizedSenders": [
    {
      "id": "ais_2rj4l7hmrrrcv",
      "type": "domain",
      "value": "vendor.com",
      "createdAt": "2026-09-19T14:05:22.000Z"
    }
  ]
}
```

Bills from the inbox have `source: email` and no owner until someone claims
them in the dashboard. [List bills](/api-reference/bills/list) with
`source=email` to pick them up.

## Who can send bills

Without any extra setup, the inbox accepts email from:

* your team's Slash users
* addresses on your company's own domain
* the email domains of your vendor contacts

Anything else is bounced, with a reply explaining why.

## Allow more senders

To accept invoices from a bookkeeper or a new supplier, allow their address
or their whole domain with
[Allowlist an inbox sender](/api-reference/bills/inbox/senders/add):

```bash theme={null}
curl https://api.slash.com/v2/bills/inbox/senders \
  -X POST \
  -H "X-API-Key: $SLASH_API_KEY" \
  -H "x-legal-entity: $SLASH_LEGAL_ENTITY_ID" \
  -H "Content-Type: application/json" \
  -d '{ "type": "email", "value": "books@gmail.com" }'
```

Use `type: email` for one address and `type: domain` for everyone at a
domain. Public providers such as `gmail.com` can't be allowed as a domain,
because anyone could sign up there; allow the individual address instead.

[Remove an inbox sender](/api-reference/bills/inbox/senders/remove) to stop
accepting their email. Bills they already sent are kept.
