Linear

Turn feedback into action. Automatically create Linear issues when feedback is submitted, and keep statuses synchronized between Quackback and Linear. When an issue moves through your Linear workflow, the linked feedback post updates too.

Overview

The Linear integration enables:

  • Create Linear issues from feedback posts -- automatically create an issue when new feedback is submitted
  • Link posts to issues -- link feedback posts to Linear issues for traceability
  • Status sync -- keep feedback status in sync with Linear issue workflow states via inbound webhooks

Prerequisites

  • Admin access to your Quackback workspace
  • A Linear workspace with admin access
  • A Linear OAuth application (created at Linear Settings > API)

Setup

1. Create a Linear OAuth Application

  1. Go to Linear Settings > API
  2. Create a new OAuth application
  3. Copy the Client ID and Client Secret

2. Configure Platform Credentials

  1. Go to Admin → Settings → Integrations → Linear
  2. Enter the following credentials:
    • Client ID from your Linear OAuth application
    • Client Secret from your Linear OAuth application

3. Connect Your Workspace

  1. Click Connect to Linear
  2. You'll be redirected to Linear to authorize the application
  3. Review the permissions and click Authorize

The app requests these OAuth scopes: read, write, issues:create, admin.

4. Select a Team

Back in Quackback:

  1. Choose the Linear team where issues should be created
  2. Issues will be created in this team when new feedback is submitted

5. Configure Status Mappings

Map Linear workflow states to Quackback statuses:

  1. Go to the Linear integration settings
  2. Configure status mappings between Linear states and Quackback statuses
  3. Mappings are configurable per workspace -- map each Linear state name to the corresponding Quackback status, or set it to ignore

Status sync works bidirectionally via Linear webhooks. When a linked Linear issue changes state, the corresponding Quackback post status updates automatically.

6. Configure Events

Choose which events trigger Linear actions:

EventAction
New postCreate a Linear issue with the feedback details

The Linear integration currently creates issues only for post.created events. Status changes and comments are handled through the status sync mechanism rather than creating new issues.

7. Save and Test

  1. Click Save
  2. Submit test feedback to verify an issue is created in Linear

Issue Format

When a new feedback post triggers issue creation, the Linear issue includes:

  • Title: The feedback post title
  • Description: The post content, followed by metadata including the author, board, vote count, and a link back to the post in Quackback

Status Sync

When status sync is configured, Quackback registers a webhook with Linear to receive issue updates. When a linked Linear issue's workflow state changes:

  1. Linear sends a webhook to Quackback
  2. Quackback looks up the status mapping for the new Linear state
  3. If a mapping exists, the linked feedback post's status is updated

The webhook signature is verified using HMAC-SHA256 via the Linear-Signature header.

On post delete

When you delete a feedback post with a linked Linear issue, you can archive the issue at the same time. The delete dialog shows a checkbox for each linked issue.

To pre-check this by default, enable the On post delete toggle in the Linear integration settings. You can always override the default per-delete.

Manage the integration

Pause

Temporarily stop the integration:

  1. Go to Admin → Settings → Integrations → Linear
  2. Toggle Enabled off
  3. Issue creation and status sync pause, but the connection remains

Reconnect

If you see connection errors:

  1. Click Reconnect
  2. Re-authorize in Linear
  3. Tokens are automatically refreshed when they expire

Disconnect

To fully remove the integration:

  1. Go to Admin → Settings → Integrations → Linear
  2. Click Disconnect
  3. Confirm the action

Disconnecting revokes the OAuth token with Linear and removes the registered webhook.

Troubleshooting

Issues Not Being Created

  1. Check integration status -- look for errors in settings
  2. Verify team selection -- ensure a Linear team is selected
  3. Check event mappings -- confirm post.created is mapped
  4. Admin permissions -- the connected Linear account must have admin permissions to create webhooks

Status Sync Not Working

  1. Check status mappings -- ensure Linear states are mapped to Quackback statuses
  2. Verify webhook -- the Linear webhook may need to be re-registered
  3. Check Linear permissions -- the connected account needs admin access

"Authentication Failed" Error

Linear OAuth tokens expire and are automatically refreshed. If refresh fails:

  1. Click Reconnect
  2. Re-authorize the app in Linear
