+
+Arguments can be marked as `required: true` which means the value must be present and not `null`.
+If a required argument's value can be `null`, use the `required: :nullable` declaration.

+Example:
+

+```
+
+In the above example, the `due_date` argument must be given, but unlike the GraphQL spec, the value can be `null`.
+This allows 'unsetting' the due date in a single mutation rather than creating a new mutation for removing the due date.

+# Configure the Jira integration in GitLab
+
+You can set up the [Jira integration](index.md#jira-integration)
+by configuring your project settings in GitLab.
+You can also configure these settings at a [group level](../../user/admin_area/settings/project_integration_management.md#manage-group-level-default-settings-for-a-project-integration),
+and for self-managed GitLab, at an [instance level](../../user/admin_area/settings/project_integration_management.md#manage-instance-level-default-settings-for-a-project-integration).
+
+Prerequisites:
+
+- Ensure your GitLab installation does not use a [relative URL](development_panel.md#limitations).
+- For **Jira Server**, ensure you have a Jira username and password.
+  See [authentication in Jira](index.md#authentication-in-jira).
+- For **Jira on Atlassian cloud**, ensure you have an API token
+  and the email address you used to create the token.
+  See [authentication in Jira](index.md#authentication-in-jira).
+
+To configure your project:
+
+1. Go to your project and select [**Settings > Integrations**](../../user/project/integrations/overview.md#accessing-integrations).
+1. Select **Jira**.
+1. Select **Enable integration**.
+1. Select **Trigger** actions. Your choice determines whether a mention of Jira issue
+   (in a GitLab commit, merge request, or both) creates a cross-link in Jira back to GitLab.
+1. To comment in the Jira issue when a **Trigger** action is made in GitLab, select
+   **Enable comments**.
+1. To transition Jira issues when a
+   [closing reference](../../user/project/issues/managing_issues.md#closing-issues-automatically)
+   is made in GitLab, select **Enable Jira transitions**.
+1. Provide Jira configuration information:
+   - **Web URL**: The base URL to the Jira instance web interface you're linking to
+     this GitLab project, such as `https://jira.example.com`.
+   - **Jira API URL**: The base URL to the Jira instance API, such as `https://jira-api.example.com`.
+     Defaults to the **Web URL** value if not set. Leave blank if using **Jira on Atlassian cloud**.
+   - **Username or Email**:
+     For **Jira Server**, use `username`. For **Jira on Atlassian cloud**, use `email`.
+   - **Password/API token**:
+     Use `password` for **Jira Server** or `API token` for **Jira on Atlassian cloud**.
+1. To enable users to view Jira issues inside the GitLab project **(PREMIUM)**, select **Enable Jira issues** and
+   enter a Jira project key.
+
+   You can display issues only from a single Jira project in a given GitLab project.
+
+   WARNING:
+   If you enable Jira issues with this setting, all users with access to this GitLab project
+   can view all issues from the specified Jira project.
+
+1. To enable issue creation for vulnerabilities **(ULTIMATE)**, select **Enable Jira issues creation from vulnerabilities**.
+1. Select the **Jira issue type**. If the dropdown is empty, select refresh (**{retry}**) and try again.
+1. To verify the Jira connection is working, select **Test settings**.
+1. Select **Save changes**.
+
+Your GitLab project can now interact with all Jira projects in your instance and the project now
+displays a Jira link that opens the Jira project.
