# Check InMail Seat

> Know whether a Sales Nav seat can send InMails right now, without sending one.

## Overview

LinkedIn puts a **monthly fuse** on every Sales Nav seat, independent of its remaining InMail credits: once tripped, every InMail is refused with `INMAIL_MONTHLY_FUSE_LIMIT`, and it lifts on LinkedIn's own schedule. This action tells you the seat's state before you queue sends, so you can route leads to a seat that can actually deliver.

It also reports whether the seat currently sees the **Open Profile badge** (see [Check InMail](/api-reference/v2/profiles/check-inmail)) and its InMail credit balance.

<Note>This endpoint consumes **1 credit**. Nothing is sent: the fuse is probed with an empty message LinkedIn refuses before it could ever deliver. Requires a Sales Nav seat on the account. Ignore this if you're on per-seat pricing: usage is unlimited.</Note>

## Request

<ParamField header="x-api-key" type="string" required>
  Your API key for authentication.
</ParamField>

<ParamField body="account_id" type="string" required>
  The unique identifier of the account to use. Must have a Sales Nav seat.
</ParamField>

<ParamField body="action" type="string" required>
  Must be `"check_inmail_seat"`.
</ParamField>

<ParamField body="params" type="object">
  <Expandable title="params properties">
    <ParamField body="profile" type="string">
      Optional. A lead in the seat's network (profile URL, slug, member id or Sales Nav reference) to probe against. When omitted, the API picks one itself.
    </ParamField>
  </Expandable>
</ParamField>

## Response

<ResponseField name="success" type="boolean">
  Indicates whether the request was successful.
</ResponseField>

<ResponseField name="data" type="object">
  <Expandable title="data properties">
    <ResponseField name="seat_status" type="string">
      `ok` (InMails go through), `monthly_limit` (LinkedIn's monthly fuse is tripped), `under_review` (LinkedIn has frozen the Sales Nav account; the member must clear it on linkedin.com) or `rate_limited` (a passing throttle, retry in a few minutes).
    </ResponseField>

    <ResponseField name="can_send_inmail" type="boolean">`true` only when `seat_status` is `ok`.</ResponseField>
    <ResponseField name="open_profile_badge_visible" type="boolean | null">Whether the seat currently sees the Open Profile badge. When `false`, [Check InMail](/api-reference/v2/profiles/check-inmail) and Sales Nav search results from this seat report every member as not open and must not be trusted.</ResponseField>
    <ResponseField name="inmail_credits" type="integer | null">InMail credits left on the seat. Not what decides `seat_status`: a fused seat keeps its credits.</ResponseField>
    <ResponseField name="linkedin_code" type="string | null">LinkedIn's own code when the seat is refused, e.g. `INMAIL_MONTHLY_FUSE_LIMIT`, `ACCOUNT_UNDER_REVIEW`.</ResponseField>
    <ResponseField name="message" type="string">Human-readable explanation of the state.</ResponseField>
    <ResponseField name="checked_at" type="string">ISO 8601 timestamp of the probe.</ResponseField>
