# Assignee Rules

You can set a default assignee for Jira tickets in the Jira integration settings in the Nullify dashboard.

A Jira Cloud user is identified by an **account ID** — an alphanumeric string such as `5b10a2844c20165700ede21g` (not a numeric id). You can find a user's account ID in their Jira profile: open the user's profile and copy the ID from the URL, or use the Jira admin user management page.

New Jira and Linear tickets require an assignee. Nullify first uses a person selected for that ticket, then the integration's default assignee, then the confirmed security owner. A security owner can be a person or a team's current lead. The account must be active and assignable in the destination project.

The default assignee setting is optional when a confirmed security owner is available. Existing tenants need to configure one of these choices before automatic ticket creation can succeed. If neither resolves to a valid account, automatic creation stops and manual creation asks you to select an assignee. Provider outages can be retried without changing the selected account.

The recommended owner in the ticket body is separate from its assignee. It identifies the author of the relevant source change when available; otherwise it says `Recommended owner: owner unknown`.

When configuring the default assignee, provide the user's account ID so Nullify assigns the ticket to exactly that user. You may also record the user's display name alongside it for readability, but the account ID is what determines the assignee.

Omitting `defaultAssigneeId` from a configuration update preserves the saved account, including when the project or team changes. An empty string clears it. Ticket creation validates the saved account against the destination project or team before using it. If it is no longer assignable there, Nullify tries the confirmed security owner and otherwise requires an explicit assignee. Provide a new default or clear the old one when changing destinations if you do not want it retained.
