/v3/projects/{project_id}/analytics/search/no-results

Returns a paginated list of keywords that produced zero search results. Use this to identify content gaps — these are topics your users are looking for but cannot find. Consider creating new articles for frequently searched no-result keywords. Requires ViewAnalytics permission.

Security

OAuth

All V3 endpoints require a Bearer token. Generate tokens in the Document360 portal under Settings > API Tokens. Tokens are project-scoped, require the customerApi scope, and do not expire by default. Tokens can be revoked at any time from the portal. Include the token in every request: Authorization: Bearer <your-token>. Alternatively, use the Authorize button below to sign in via OAuth2 Authorization Code flow with PKCE.
