# Linear credentials

You can use these credentials to authenticate the following nodes:

* [Linear Trigger](/integrations/builtin/trigger-nodes/n8n-nodes-base.lineartrigger.md)
* [Linear](/integrations/builtin/app-nodes/n8n-nodes-base.linear.md)

## Prerequisites <a href="#prerequisites" id="prerequisites"></a>

Create a [Linear](https://linear.app/) account.

## Supported authentication methods <a href="#supported-authentication-methods" id="supported-authentication-methods"></a>

* API key
* OAuth2

## Related resources <a href="#related-resources" id="related-resources"></a>

Refer to [Linear's API documentation](https://developers.linear.app/docs/graphql/working-with-the-graphql-api) for more information about the service.

## Using API key <a href="#using-api-key" id="using-api-key"></a>

To configure this credential, you'll need:

* A personal **API Key**: Create a dedicated personal API key in your [**Settings** > **Security & access**](https://linear.app/n8n/settings/account/security). Refer to the [Linear Personal API keys documentation](https://linear.app/developers/graphql#personal-api-keys) for more information.

## Using OAuth2 <a href="#using-oauth2" id="using-oauth2"></a>

To configure this credential, you'll need:

* A **Client ID**: Generated when you create a new OAuth2 application.
* A **Client Secret**: Generated when you create a new OAuth2 application.
* Select the **Actor**: The actor defines how the OAuth2 application should create issues, comments and other changes. Options include:
  * **User** (Linear's default): The application creates resources as the authorizing user. Use this option if you want each user to do their own authentication.
  * **Application**: The application creates resources as itself. Use this option if you have only one user (like an admin) authorizing the application.
* To use this credential with the [Linear Trigger](/integrations/builtin/trigger-nodes/n8n-nodes-base.lineartrigger.md) node, you must enable the **Include Admin Scope** toggle.

Refer to the [Linear OAuth2 Authentication documentation](https://developers.linear.app/docs/oauth/authentication) for more detailed instructions and explanations. Use the n8n **OAuth Redirect URL** as the **Redirect callback URL** in your Linear OAuth2 application.

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.n8n.io/integrations/builtin/credentials/linear.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
