Linear
This page contains the setup guide and reference information for the Linear source connector.
Linear is a project management and issue tracking tool designed for software teams. It provides a streamlined interface for managing issues, sprints, and product roadmaps with a focus on speed and simplicity.
Prerequisites
- A Linear account
- One of the following authentication methods:
- API Key: A Linear personal API key.
- OAuth 2.0: A Linear OAuth app with a client ID, client secret, and refresh token.
Setup guide
Step 1: Choose an authentication method
The Linear source connector supports API key and OAuth 2.0 authentication.
API key
- Log in to your Linear account.
- Navigate to Settings by clicking your workspace name in the sidebar.
- Select Security & access from the settings menu.
- Scroll to the Personal API keys section.
- Click Create key, give the key a descriptive label (for example,
airbyte), and click Create. - Copy the API key and store it securely. Linear only displays the key once.
The API key inherits your user's permissions in the workspace. The connector can only sync data you can see in Linear.
For more information, see the Linear GraphQL API documentation.
OAuth 2.0
Create a Linear OAuth app and configure the redirect callback URL for your Airbyte deployment. The connector requests the read and customer:read scopes. Linear returns an access token and refresh token after the OAuth flow, and the connector uses the refresh token to refresh access tokens when they expire.
For more information, see the Linear OAuth 2.0 authentication documentation.
Step 2: Configure the Linear connector in Airbyte
- In the Airbyte UI, navigate to Sources and click + New source.
- Select Linear from the list of available sources.
- Enter a Source name of your choosing.
- For Authentication, choose API Key or OAuth 2.0.
- Enter the required credentials for your authentication method.
- Optionally, enter a Start Date in ISO 8601 format (for example,
2024-01-01T00:00:00.000Z). Only records updated on or after this date are replicated for streams that support incremental sync. If you leave this field empty, the connector defaults to two years before the time of the first sync. - Optionally, adjust the Number of concurrent workers (default 4, range 1–10). Higher values speed up syncs but increase the risk of hitting Linear's rate limits. Users on API key authentication (2,500 requests/hour) should generally stay at or below the default. Users on OAuth authentication (5,000 requests/hour) may increase this value if they have observed headroom in their rate-limit usage.
- Click Set up source and wait for the connection test to complete.
Existing connections that authenticated with a Linear API key continue to use API key authentication after upgrading to connector version 0.2.1 or later. If you upgraded an API key connection to 0.2.0 and it no longer passes connection checks, upgrade to 0.2.1 or later.
Supported sync modes
The Linear source connector supports the following sync modes:
Streams that support incremental sync use the updatedAt field as the cursor. The Start Date you set when configuring the connector is the lower bound for the first incremental sync. Subsequent syncs use the most recent updatedAt value from the previous sync as the new lower bound.
The following streams are full-refresh only because the Linear GraphQL API doesn't expose a filter argument that the connector can use to request only updated records: project_statuses, issue_relations, customer_statuses, and customer_tiers.
Supported streams
The Linear source connector supports the following streams. Streams marked as incremental use updatedAt as the cursor field.
| Stream | Incremental | Description |
|---|---|---|
attachments | Yes | File and link attachments on issues. |
comments | Yes | Comments posted on issues. |
customer_needs | Yes | Customer needs associated with issues. |
customers | Yes | Customer records tracked in Linear's customer requests feature. |
customer_statuses | No | Status definitions for customer records. |
customer_tiers | No | Tier definitions for customer records. |
cycles | Yes | Cycles (sprints) for each team. |
issue_labels | Yes | Labels that can be applied to issues. |
issue_relations | No | Relationships between issues (for example, blocks and duplicates). |
issues | Yes | Issues in every team, including archived issues. |
project_milestones | Yes | Milestones defined inside projects. |
project_statuses | No | Status definitions for projects. |
projects | Yes | Projects across all teams. |
teams | Yes | Teams in your Linear workspace. |
users | Yes | Users in your Linear workspace. |
workflow_states | Yes | Workflow states (for example, Todo, In Progress, Done) defined by each team. |
Limitations and troubleshooting
Rate limiting
The Linear API uses a leaky bucket algorithm for rate limiting. The connector detects rate-limit errors returned by the API and automatically backs off until the rate-limit window resets. Syncs may slow down during backoff periods but will resume without manual intervention.
Linear enforces three types of rate limits:
- Request limits: 2,500 requests per user per hour for API key authentication, 5,000 for OAuth app authentication. All requests by the same user share the same quota.
- Endpoint-specific limits: Certain queries have lower per-endpoint limits. The connector respects the
X-RateLimit-Endpoint-Requests-Resetheader when these are hit. - Complexity limits: Each query's complexity is calculated based on the number of requested fields and pagination depth. The maximum single-query complexity is 10,000 points. The hourly complexity budget is 3,000,000 points for API key authentication and 2,000,000 for OAuth.
Workspace-level OAuth applications receive dynamically increased limits based on the number of paid seats. For more information, see the Linear rate limiting documentation.
Data availability
The connector retrieves data that the authenticated user has access to. If you cannot see certain teams, projects, or issues in your synced data, verify that your Linear account has the appropriate permissions.
IP allow list
If you use Airbyte Cloud and your organization restricts access to specific IPs, add the Airbyte Cloud IP addresses to your allow list.
Reference
This connector uses the Linear GraphQL API. All API requests use the https://api.linear.app/graphql endpoint.
For programmatic configuration, use these parameter names:
| Field | Required | Description |
|---|---|---|
credentials.auth_type | Yes | Authentication method. Valid values are API Key and OAuth2.0. |
credentials.api_key | Required for API key authentication | Linear personal API key. |
credentials.client_id | Required for OAuth 2.0 authentication | Client ID of your Linear OAuth app. |
credentials.client_secret | Required for OAuth 2.0 authentication | Client secret of your Linear OAuth app. |
credentials.refresh_token | Required for OAuth 2.0 authentication | Refresh token returned by the Linear OAuth flow. |
start_date | No | UTC date and time in ISO 8601 format. Records updated before this date aren't replicated for streams that support incremental sync. If unset, defaults to two years before the first sync. |
num_workers | No | Number of worker threads used to read streams in parallel (default 4, range 1–10). Higher values speed up syncs but increase the risk of hitting rate limits. |
