# searchThreadLinkCandidates

> Searches for external entities (e.g. Jira issues) that can be linked to a thread. Filter by `sourceType` to scope the search to a specific issue tracker, and provide a free-text `searchQuery` to match against issue titles or identifiers. Returns candidates that can then be passed to `createThreadLink`. Requires a connected issue tracker integration for the specified source type.
