# Send Invoice record

`POST /public/v1/invoices/{record_number}/send/`

Send an existing invoice by email, with the invoice PDF attached.

The path `{record_number}` is the invoice `number`.

The body matches `POST /api/email_send/invoice/` (`to_emails`, `cc_emails`, `bcc_emails`,
`pdf_content`, `subject`, `message`, `sandbox`). `pdf_content` is optional. If it is omitted
or empty, the worker captures the invoice PDF. If `subject` or `message` is omitted or empty,
company invoice email templates are used, then organization defaults.

If `to_emails` is omitted or empty, the customer email on the invoice is used.

A 200 response means the send was accepted, not that
the provider has delivered the message. Emails are sent in the background
