# Send Reply

`POST /inbox/{reply_id}/send`

## Request

- Base URL: `https://be.graph8.com/api/v1`
- URL: `https://be.graph8.com/api/v1/inbox/{reply_id}/send`
- Auth: HTTP bearer

Send a reply through the specified channel (email, sms, or linkedin).

## Path parameters

- `reply_id` string, required: Thread/reply ID

## Headers

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

## Request body

- SendRequest
  - `body` string, required: Message body to send
  - `channel` 'email' | 'sms' | 'linkedin', required
  - `subject` string, nullable: Email subject (optional, for email channel)
  - `to` string, nullable: Recipient override (email address or phone number). Omit it to reply to the thread's contact: the contact's email (else the last inbound sender) for email, the thread's contact number for SMS. Not used for LinkedIn.
  - `from_address` string, nullable: Sender (mailbox email, your phone number, or numeric LinkedIn account ID). Omit it to send from the thread's own mailbox / number / LinkedIn account (the thread's `mailbox`, `from_number` or `linkedin_account_id`). You still need permission to send as that sender.

    - `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.
