# Search LinkedIn conversations

> List LinkedIn message threads for the team across both messenger surfaces (basic LinkedIn + Sales Navigator) with operator-object filters (account, contact ids, conversation_hash = LinkedIn's own 2-…== thread id, messenger_type, event-count, activity / message-sync clock ranges), sort, cursor pagination, and include[] for the parent account and the last 50 messages. Live rows by default; page_size:0 for count-only. Given a thread id by the user, look it up with filter.filter {"conversation_hash": {"eq": "<hash>"}}: q is a nickname LIKE and will not find it.

Contract:
- MCP tool `search_linkedin_conversations`, registry package `mcp.linkedin/linkedin_conversations`, mount `linkedin.messaging`.
- Operation `search`, response envelope `search`.
- Flags: read only.



## OpenAPI

````yaml /api-reference/linkedin/openapi.yaml post /api/linkedin-conversations/search
openapi: 3.0.3
info:
  title: 'GTM API public contract: gtm.service.linkedin'
  description: >-
    Connected LinkedIn accounts and everything driven through them: account
    health and smart limits, conversations and messages, the connection graph,
    outbound posting, scraping, profile and company enrichment, and the
    antidetect browsers that execute it all.


    GENERATED. This document is projected from the Zod MCP tool registry in
    `product/mcp/gtm.mcp` (one tool per public endpoint, 1:1). Do not edit it by
    hand; edit the tool definition and regenerate with `pnpm openapi:public`.


    Surface: the public `/api` contract of `gtm.service.linkedin`, 189
    operations. This is the only OpenAPI document the platform publishes.
    Internal (`/internal`) and health endpoints are deliberately absent: they
    are not part of any contract, they can change without notice, and the
    service source is their only description.


    Conventions:

    - Auth is a bearer JWT, optionally narrowed by the `Team-SID` header.

    - Every success body is an MCP envelope: `success: true` plus one typed
    `operation` shape (`search`, `get`, `create`, `update`, `delete`, `metrics`,
    `group_by`, `action`), and a `meta` block with `trace_id` for support.

    - Every failure is the same `McpError` envelope with a code from a fixed
    16-code taxonomy, so a client maps errors once.

    - Lists page with `page_size` (0 to 500, default 50) plus an opaque forward
    `cursor`; `page_size: 0` returns counts only.

    - On `GET` and `DELETE`, object-valued query parameters (`filter`, `sort`)
    travel as JSON text and array-valued ones repeat as `name[]=value`.

    - The MCP-only `_meta` field (usage analytics) never reaches the backend and
    is not part of this contract.
