# LinkedIn Integration — Search Chats and Posts with AI

> Connect LinkedIn to Hyper to sync messages, posts, and profile data so AI agents can surface relationship context and conversation history.

LinkedIn is where professional relationships develop and business conversations happen — in direct messages, comment threads, and posts that carry real context about your network. When you connect LinkedIn to Hyper, it syncs your chat history, posts, and profile data into your shared AI memory layer. Agents can search past conversations by participant or topic, find relevant posts by keyword, and retrieve profile information — giving you relationship context exactly when you need it without switching tabs or scrolling endlessly.

## Connect LinkedIn

LinkedIn uses a browser-hosted native authentication flow managed securely by the Hyper desktop app. You enter your LinkedIn credentials directly into the flow, and Hyper handles secure session management on your behalf.

<Steps>
  <Step title="Open Settings in the Hyper desktop app">
    Launch the Hyper desktop app and click **Settings** in the navigation, then select **Connections**.
  </Step>

  <Step title="Click Connect next to LinkedIn">
    Find LinkedIn in the list of available integrations and click **Connect**.
  </Step>

  <Step title="Enter your LinkedIn credentials">
    A browser-hosted authentication window opens within the Hyper app. Enter your LinkedIn email address and password. Hyper manages the session securely — your credentials are used only to establish the LinkedIn session and are not persisted in plaintext.
  </Step>

  <Step title="Wait for the initial sync to complete">
    Hyper begins fetching your chats, posts, and profile data. The sync is capped at a 90-day lookback window. Progress is visible in **Settings → Connections**.
  </Step>
</Steps>

<Warning>
  LinkedIn does not offer a public OAuth API for this type of access. Hyper's LinkedIn integration uses a native browser session approach. Use your personal LinkedIn credentials — do not use a shared or service account.
</Warning>

## What Hyper Syncs

| What's synced           | Details                                                               |
| ----------------------- | --------------------------------------------------------------------- |
| **Chats**               | Direct message threads with connection names and conversation content |
| **Posts**               | LinkedIn posts from your feed or profile                              |
| **Profile data**        | Profile information for contacts encountered in chats and posts       |
| **Lookback window**     | Capped at 90 days of history                                          |
| **Incremental updates** | New messages and posts are synced incrementally                       |
| **Deduplication**       | Content-hash dedup prevents duplicate entries                         |

<Info>
  Hyper reads your LinkedIn data only — it never posts, messages, likes, comments, or modifies anything on your LinkedIn account.
</Info>

<Note>
  The 90-day lookback cap keeps the initial sync fast and focused on recent, actionable relationship context.
</Note>

## Search LinkedIn with AI Agents

Once your LinkedIn data is synced, your AI agents can search chats and posts or retrieve specific profiles and conversation threads.

**Example agent queries:**

```text theme={null}
Find my LinkedIn messages with Sarah from Acme Corp
Search LinkedIn chats mentioning "partnership proposal"
Show me recent posts about AI infrastructure from my network
Find the conversation thread with the recruiter from TechCo
Read my chat history with john.doe@example.com
Search posts containing "Series B announcement"
Show me the LinkedIn profile for the person who messaged me about the consulting project
```

**What agents can do:**

| Action               | Description                                                    |
| -------------------- | -------------------------------------------------------------- |
| **Search chats**     | Find message threads by participant name or conversation title |
| **Search posts**     | Find posts by keyword or phrase in the post text               |
| **Read chat thread** | Retrieve the full message history for a specific conversation  |
| **Read post**        | Fetch the full content of a specific post                      |
| **Read profile**     | Retrieve profile data for a specific LinkedIn contact          |

<Accordion title="About LinkedIn data freshness">
  Hyper syncs LinkedIn data incrementally — new messages and posts are pulled in regularly, subject to LinkedIn's rate constraints. If you notice a recent conversation isn't appearing, wait a few minutes and try again as the sync catches up.
</Accordion>

## Reconnect LinkedIn

If the LinkedIn session expires or is invalidated, Hyper will show a **Reconnect** prompt in **Settings → Connections**.

<Steps>
  <Step title="Go to Settings → Connections">
    Open the Hyper desktop app and navigate to **Settings → Connections**.
  </Step>

  <Step title="Click Reconnect next to LinkedIn">
    Click the **Reconnect** button to open the LinkedIn authentication flow.
  </Step>

  <Step title="Re-enter your LinkedIn credentials">
    Complete the sign-in in the browser-hosted window. Hyper re-establishes the session and resumes incremental sync. Your previously indexed data is preserved.
  </Step>
</Steps>

## Disconnect LinkedIn

To remove LinkedIn from Hyper, go to **Settings → Connections**, find LinkedIn, and click **Disconnect**. Hyper cleanly terminates your LinkedIn session and stops all future syncing. Previously indexed chat, post, and profile data will be removed from your memory layer.

<Warning>
  Disconnecting LinkedIn removes all synced data from Hyper's memory layer and terminates the LinkedIn session. If you reconnect later, Hyper will re-sync from the 90-day lookback window.
</Warning>
