## Overview

Linear is a modern issue tracking and project management platform designed for high-performance software teams. It provides streamlined workflows, keyboard-first design, and powerful integrations to help teams build products faster.

### Linear Data Structure

The connector understands Linear's hierarchical data model:

* **Teams**
  * **Issues** (with comments, attachments, documents, and embedded files)
  * **Projects** (with milestones, updates, external links, and documents)
* **Users** (team members with profiles and emails)

### What Gets Synced

The connector indexes the following content for AI-powered search:

| Content Type    | Details                                                                                                                           |
| --------------- | --------------------------------------------------------------------------------------------------------------------------------- |
| **Issues**      | Title, description, status, priority, labels, identifiers (e.g., ENG-123), assignee, creator, type, and parent issue (sub-issues) |
| **Comments**    | Full comment threads organized by thread ID with author info and timestamps                                                       |
| **Attachments** | External links attached to issues                                                                                                 |
| **Documents**   | Linear documents linked to issues and projects                                                                                    |
| **Files**       | Files from descriptions/comments (images as base64, others as FileRecord)                                                         |
| **Projects**    | Description, content, milestones, updates, comments, external links, and documents                                                |
| **Users**       | Profiles with IDs, emails, and display names                                                                                      |
| **Permissions** | Team-level access controls (public vs. private teams)                                                                             |

## Configuration Guide

The Linear connector uses **OAuth 2.0** for authentication. Linear's OAuth apps return refresh tokens that auto-refresh, so a single authorization keeps syncing indefinitely.

#### Step 1: Access Linear API settings

1. Go to [linear.app/settings/api](https://linear.app/settings/api) and sign in with your Linear account (must have admin access to your workspace).
2. You'll see the **API** page where you create and manage OAuth 2.0 applications.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/GMZnbT0yvhmRGT64/images/connectors/linear/api_settings.png?fit=max&auto=format&n=GMZnbT0yvhmRGT64&q=85&s=8ca809758034d32437d86533ade53f70" alt="Linear API Settings Page" className="block mx-auto w-11/12" width="1908" height="809" data-path="images/connectors/linear/api_settings.png" />
</div>

<Info>
  It is recommended to create a dedicated Linear workspace for managing OAuth apps, since any admin on the workspace can see the application credentials.
</Info>

#### Step 2: Get the Redirect URL from PipesHub

Before creating the OAuth application in Linear, copy the Redirect URL from PipesHub.

1. In PipesHub, go to **Workspace Settings** → **Connectors**, find **Linear**, and click **+ Setup** for a new instance.
2. The connector panel opens as a right-side drawer. On the **Authenticate Instance** tab, copy the **Redirect URL**.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/murfsbwGziFofuQn/images/connectors/linear/linear_config.png?fit=max&auto=format&n=murfsbwGziFofuQn&q=85&s=ff749232a485d03fc9d93ae6eaa3834b" alt="PipesHub Linear Authenticate Instance tab — copy the Redirect URL" className="block mx-auto w-11/12" width="1901" height="907" data-path="images/connectors/linear/linear_config.png" />
</div>

#### Step 3: Create a new OAuth 2.0 application

1. Back on the Linear **API** page, find the **OAuth Applications** section.
2. Click the **+** button to create a new application.
3. Fill in the application details:
   * **Application name:** a meaningful name (e.g., `PipesHub Linear Connector`)
   * **Developer name:** your name or organization name
   * **Developer URL:** your website URL (e.g., `https://your-domain.com`)
   * **Description:** optional description of the application
   * **Callback URLs:** paste the Redirect URL you copied from PipesHub (Step 2)

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/GMZnbT0yvhmRGT64/images/connectors/linear/create_oauth_app.png?fit=max&auto=format&n=GMZnbT0yvhmRGT64&q=85&s=f86523853874d7fa1836389df987b13f" alt="Create OAuth 2.0 Application Form" className="block mx-auto w-11/12" width="1905" height="862" data-path="images/connectors/linear/create_oauth_app.png" />
</div>

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/GMZnbT0yvhmRGT64/images/connectors/linear/oauth_additional_scopes.png?fit=max&auto=format&n=GMZnbT0yvhmRGT64&q=85&s=4dac61bed6984f145948aefac4098d9b" alt="Linear OAuth Application Additional Scopes" className="block mx-auto w-11/12" width="1919" height="840" data-path="images/connectors/linear/oauth_additional_scopes.png" />
</div>

4. Configure the additional settings (leave all toggles **OFF**):
   * **Public** — keep OFF; the connector is only for your organization
   * **Client credentials** — keep OFF; not needed for standard OAuth flow
   * **Webhooks** — keep OFF; the connector uses scheduled polling

5. Click **Create** to create the application.

<Warning>
  The Callback URL must match exactly between Linear and PipesHub. Any mismatch — trailing slash, protocol, casing — will cause authentication to fail.
</Warning>

<Info>
  OAuth 2.0 applications created from October 1, 2025 onwards have refresh tokens enabled by default. Access tokens last 24 hours and are automatically refreshed.
</Info>

#### Step 4: Copy Client ID and Client Secret

After creating the application, you'll see the application settings page.

1. Copy the **Client ID** — used as **Client ID** in PipesHub.
2. Click to reveal and copy the **Client Secret** — used as **Client Secret** in PipesHub.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/GMZnbT0yvhmRGT64/images/connectors/linear/oauth_credentials.png?fit=max&auto=format&n=GMZnbT0yvhmRGT64&q=85&s=9cde76bfd4d4a1a2912a18d8fd546b2c" alt="OAuth 2.0 Credentials" className="block mx-auto w-11/12" width="1901" height="859" data-path="images/connectors/linear/oauth_credentials.png" />
</div>

<Warning>
  Store the Client Secret securely. It can be regenerated if needed, but you'll have to update your PipesHub configuration with the new value and re-authorize.
</Warning>

#### Step 5: Authenticate Instance tab — enter credentials

The connector drawer in PipesHub has three tabs: **Authenticate Instance**, **Authorize**, and **Configure Records**. Return to the **Authenticate Instance** tab.

1. Confirm the **Redirect URL** matches the Callback URL you saved in Linear in Step 3.
2. If your admin has pre-registered an OAuth app, pick it from the **OAuth app** dropdown. Otherwise leave it blank and enter credentials manually.
3. Enter:
   * **Client ID** — from Step 4
   * **Client Secret** — from Step 4
4. Click **Next** to move to the **Authorize** tab.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/murfsbwGziFofuQn/images/connectors/linear/connector_add_creds.png?fit=max&auto=format&n=murfsbwGziFofuQn&q=85&s=a7c8bc4d5583858031bf3e791ec69df1" alt="Authenticate Instance tab — enter Client ID and Client Secret" className="block mx-auto w-11/12" width="1898" height="896" data-path="images/connectors/linear/connector_add_creds.png" />
</div>

#### Step 6: Authorize tab — complete the OAuth flow

On the **Authorize** tab, all the OAuth authorization work happens. The tab shows an **Authenticate** button to kick off the OAuth handshake.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/murfsbwGziFofuQn/images/connectors/linear/connector_authenticated.png?fit=max&auto=format&n=murfsbwGziFofuQn&q=85&s=80a5c3a554a1980057db0836e5904d7b" alt="PipesHub Authorize tab with the Authenticate button" className="block mx-auto w-11/12" width="1909" height="886" data-path="images/connectors/linear/connector_authenticated.png" />
</div>

1. Click **Authenticate** to start the OAuth flow. A popup opens to Linear's authorization page showing your application name and the workspace it will authenticate with. Permissions requested: **Read access to your workspace**.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/murfsbwGziFofuQn/images/connectors/linear/oauth_consent.png?fit=max&auto=format&n=murfsbwGziFofuQn&q=85&s=8a4a8820db844b640fde80be78d182a6" alt="Linear OAuth Consent Screen" className="block mx-auto w-11/12" width="1913" height="908" data-path="images/connectors/linear/oauth_consent.png" />
</div>

<Warning>
  **Authorize using the same email as your PipesHub account.** Using a different email causes permission issues on the PipesHub platform.
</Warning>

2. Click **Authorize** to grant access.
3. The popup closes and returns you to PipesHub. The connector tile shows an **Authenticated** badge with a **Reauthenticate** option.
4. Click **Next** to move to the **Configure Records** tab.

<Info>
  The connector requests only **read access** to your workspace. It does not create, modify, or delete any Linear data.
</Info>

#### Step 7: Configure Records tab — sync settings, filters, and indexing

On the **Configure Records** tab, control how the connector syncs and what gets synced.

**Sync settings** — configure your synchronization preferences first:

1. **Sync Strategy** — `Scheduled` or `Manual`.
2. **Sync Interval** — how often to sync (default: 60 minutes).

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/murfsbwGziFofuQn/images/connectors/linear/connector_configure_sync_strategy.png?fit=max&auto=format&n=murfsbwGziFofuQn&q=85&s=7c0d081c018459c27b0360b76605181c" alt="Configure Sync Strategy" className="block mx-auto w-11/12" width="1902" height="891" data-path="images/connectors/linear/connector_configure_sync_strategy.png" />
</div>

<Note>
  **Scheduled sync** runs automatically at the specified intervals. **Manual sync** requires you to trigger synchronization on-demand.
</Note>

**Sync filters** — determine which content is downloaded from Linear. Data excluded by sync filters is never downloaded.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/murfsbwGziFofuQn/images/connectors/linear/linear-filters.png?fit=max&auto=format&n=murfsbwGziFofuQn&q=85&s=857a032bf5036a33364be9df191c67ef" alt="Linear Filters Configuration" className="block mx-auto w-11/12" width="1895" height="896" data-path="images/connectors/linear/linear-filters.png" />
</div>

Available sync filters:

1. **Enable Manual Indexing** — control indexing trigger method.
   * Enabled: records are indexed only when you manually trigger it.
   * Disabled (default): records are indexed automatically after sync.

2. **Teams** — filter issues and projects by team.
   * Operator: `In` (include only) or `Not In` (exclude)
   * Selection: searchable dropdown of all your Linear teams (e.g., "Engineering", "Design", "Product")
   * Leave empty to sync all teams.

<Info>
  The team list is dynamically fetched from your Linear workspace. Type to search and filter; select multiple teams as needed.
</Info>

3. **Modified Date** — filter by last modification date. Operators: `Is After`, `Is Before`, `Is Between`.

4. **Created Date** — filter by creation date. Same operators.

**Indexing filters** — control what synced data gets processed for AI search. All data is synced, but only enabled content types are indexed.

* **Index Issues** (default: enabled) — include issue content and comments in search
* **Index Issue Attachments** (default: enabled) — include external link attachments in search
* **Index Issue Documents** (default: enabled) — include Linear documents in search
* **Index Issue and Comment Files** (default: enabled) — include files extracted from issue descriptions and comments
* **Index Projects** (default: enabled) — include project content, milestones, and updates in search

**Example configurations:**

* *Sync only Engineering team:* Teams → Operator `In` → select "Engineering"
* *Exclude archived teams:* Teams → Operator `Not In` → select archived teams
* *Recent issues only:* Modified Date → Operator `Is After` → Date `2024-06-01`
* *Index issues but not attachments:* disable **Index Issue Attachments**
* *Index everything except files:* disable **Index Issue and Comment Files**

Click **Save** to save your configuration. PipesHub confirms the instance is ready with a final dialog — **"Instance is configured and ready to sync"** — offering two choices: **I'll do it later** or **Start syncing now**.

<div className="text-center">
  <img src="https://mintcdn.com/pipeshub/murfsbwGziFofuQn/images/connectors/linear/enable_connector.png?fit=max&auto=format&n=murfsbwGziFofuQn&q=85&s=d32a5f1a48ace863d5b9f35d31e5a6c1" alt="Instance is configured and ready to sync — I'll do it later or Start syncing now" className="block mx-auto w-11/12" width="1895" height="912" data-path="images/connectors/linear/enable_connector.png" />
</div>

Choose **Start syncing now** to kick off the initial sync immediately, or **I'll do it later** to enable the connector without an immediate sync. Monitor the **Indexing Progress** to track sync completion.

## Supported Features

The Linear connector provides:

* **Full content sync** — Teams, issues, projects, comments, attachments, documents, and files
* **Incremental sync** — only fetches changes since last sync using `updatedAt` timestamps
* **Batch processing** — fetches data in optimized batches (50 issues, 10 projects per request)
* **Permission preservation** — respects team-level public/private access controls
* **Dual group tracking** — UserGroups (membership) and RecordGroups (content organization)
* **Fault tolerance** — per-team checkpoints enable sync resumption on failures
* **File handling** — images embedded as base64, other files synced as separate FileRecords

## Permission Model

Linear uses a team-based permission model:

| Team Type         | Permission Behavior                            |
| ----------------- | ---------------------------------------------- |
| **Public Teams**  | All organization members can view team content |
| **Private Teams** | Only team members can view team content        |

The connector preserves these permissions:

* For **public teams**, content is visible to all organization users in PipesHub.
* For **private teams**, content is only visible to team members in PipesHub.

  <Accordion title="Troubleshooting" icon="circle-exclamation">
    ### Common Issues

    **Invalid client credentials error:**

    * Verify Client ID and Client Secret are correct
    * Ensure you copied the full values without extra spaces
    * Check that the OAuth app is active in Linear API settings
    * Regenerate the secret if necessary and update PipesHub

    **Callback URL mismatch error:**

    * Ensure the Redirect URI in PipesHub exactly matches the callback URL in Linear
    * Check for trailing slashes or protocol differences (http vs https)
    * Update both configurations to use the same URL

    **Authorization failed:**

    * Verify you're signing in with an account that has Linear access
    * Ensure you have the necessary permissions in your Linear workspace
    * Check that the OAuth application is properly configured

    **No data syncing:**

    * Verify the connector status shows "Active"
    * Check that the authenticating user has access to Linear teams
    * Ensure teams are not archived or restricted
    * Review sync logs for specific error messages

    **Permission denied for specific issues:**

    * Verify the authenticating user has access to the team containing the issues
    * Check team privacy settings (public vs. private) in Linear
    * Ensure the user is a member of private teams

    **Missing comments or attachments:**

    * Comments are synced as part of issues - ensure "Index Issues" filter is enabled
    * Attachments require "Index Issue Attachments" filter to be enabled
    * Check that the authenticating user has permission to view comments/attachments
    * Ensure the content exists on the issues in Linear

    **Files not appearing:**

    * Only files from Linear's upload service (uploads.linear.app) are extracted
    * External file URLs from other services are not indexed
    * Check that "Index Issue and Comment Files" filter is enabled

    <Warning>
      If you modify OAuth application settings in Linear (Client ID, Secret, or callback URL), you must update the configuration in PipesHub and re-authorize the connection.
    </Warning>
  </Accordion>
</AccordionGroup>

## Connector Workflow

<AccordionGroup>
  <Accordion title="Synchronization Process" icon="sync">
    The Linear connector follows a structured synchronization process to ensure all data is accurately synced and permissions are properly maintained.

    ### Sync Order

    The connector syncs data in the following order:

    1. **Users** → Sync all Linear users with their profiles
    2. **Teams** → Sync teams with membership and permission settings
    3. **Issues** → Sync issues with comments and embedded files per team
    4. **Attachments** → Sync external links attached to issues
    5. **Documents** → Sync Linear documents linked to issues
    6. **Projects** → Sync projects with milestones, updates, and related content
    7. **Deletions** → Detect and remove deleted/archived issues and projects

    ### Full Sync vs Incremental Sync

    **Full Sync** occurs when:

    * First-time synchronization
    * Manual full sync is triggered

    **Incremental Sync** occurs when:

    * Previous sync completed successfully
    * Only fetches content modified since last sync
    * Resumes from last checkpoint if interrupted

    ### What Gets Processed

    **Issues**: Title, description, comments (organized by threads), status, priority, assignee, labels, and embedded files

    **Projects**: Description, content, milestones, updates, comments, external links, and documents

    **Attachments & Documents**: Synced separately to capture additions even when parent issue wasn't modified

    **Deletions**: Automatically detects trashed/archived content and removes from index along with related records
  </Accordion>

## FAQ

<AccordionGroup>
  <Accordion title="How long does the initial sync take?">
    The initial sync duration depends on several factors:

    * **Workspace size**: Number of issues, projects, and teams
    * **Network latency**: Connection speed to Linear's API
    * **Content complexity**: Issues with many comments and attachments take longer

    The connector fetches data in batches of 50 items per API request for optimal performance. Each team is processed sequentially with per-team checkpoints, allowing sync to resume from the last successful point if interrupted.

    **Tips to speed up initial sync:**

    * Use **team filters** to sync only the teams you need
    * Use **date filters** to exclude old/archived content
    * Disable indexing filters for content types you don't need (e.g., attachments, files)
  </Accordion>

  <Accordion title="What OAuth scopes does the connector require?">
    The Linear connector requests the following OAuth scopes:

    | Scope  | Description                                  |
    | ------ | -------------------------------------------- |
    | `read` | Read access for your account data (required) |

    <Note>
      The connector only requires the `read` scope for team synchronization, providing read-only access to your Linear data. It does **not** create, modify, or delete any Linear data.
    </Note>
  </Accordion>

  <Accordion title="Does the connector support real-time sync?">
    **Not currently**. The connector uses scheduled polling-based synchronization rather than real-time webhooks. Incremental syncs occur at the configured interval (default: 60 minutes) to capture changes.
  </Accordion>

  <Accordion title="Can I sync specific projects only?">
    Currently, the connector does not support filtering by specific projects. You can filter by:

    * **Teams**: Sync only specific teams
    * **Modified Date**: Sync only recently modified content
    * **Created Date**: Sync only recently created content

    Since projects belong to teams, filtering by team will effectively filter the associated projects as well.
  </Accordion>

  <Accordion title="Queries not returning results. What could be wrong?">
    There are three common causes:

    1. **Email mismatch** - The email used during connector authentication doesn't match your PipesHub account email. This causes permission issues preventing you from accessing synced data.
       * **Fix:** Reconfigure the connector and authenticate using the same email as your PipesHub account.

    2. **Records show in "All Records" but not in search** - Documents display in the All Records section but don't appear in search query results.
       * **Fix:** Verify sync filters in the connector settings and ensure indexing has completed. Check that the data matches your search query criteria.

    3. **Data not yet indexed** - The connector is still syncing or hasn't completed the initial indexing process.
       * **Fix:** Go to **Workspace Settings → Connectors**, check the sync status, and wait for indexing to complete.
  </Accordion>
