The rule builder renders itself from this: `available` says whether the project has the data the type reads, and `dimensions` are the keys a rule of that type can be grouped by here, including the project's own time-series tags. A type with `available` false, or a `groupBy` key not listed here, is rejected when the rule is saved. Required API key permission: `observe:alerts:read`. ## OpenAPI ````yaml /api-reference/openapi/observe.yaml get /observe/alertRuleTypes openapi: 3.1.1 info: version: 1.0.0 title: Corbado API description: > # Introduction This documentation gives an overview of all Corbado API calls to implement authentication observe. contact: name: Corbado team email: support@corbado.com url: https://www.corbado.com servers: - url: https://api.cloud.corbado.io/v1 security: - bearerAuth: [] tags: - name: ObserveFlow description: Flow search and related APIs x-group: Journeys and users - name: ObserveSubFlow description: Subflow search and related APIs x-group: Journeys and users - name: ObserveUser description: User search and related APIs x-group: Journeys and users - name: ObserveClientEnv description: Client environment search APIs x-group: Journeys and users - name: ObserveTimeSeries description: Time series query APIs x-group: Metrics and funnels - name: ObserveFunnel description: Historical funnel metrics, dictionaries and coverage. x-group: Metrics and funnels - name: ObserveEvent description: Event ingestion and event feed APIs x-group: Events - name: ObserveError description: Named authentication errors and recommendations. x-group: Error management - name: ObserveErrorFlavour description: Error variants and their impact on authentication outcomes. x-group: Error management - name: ObserveAlert description: Authentication alert rules, instances and history. x-group: Alert management - name: ObserveAnnotation description: Annotation APIs (dated notes for analytics context) x-group: Annotations - name: ObserveTableExport description: Table export file listing and download APIs x-group: Data exports - name: ObserveTimeSeriesExport description: Time-series export generation and downloads. x-group: Data exports - name: ObserveDataExport description: Data export APIs x-group: User data - name: ObserveDataDeletionJob description: Data deletion job APIs x-group: User data - name: ObserveFlowTypeDefinition description: Flow type definitions used in authentication journeys. x-group: Catalogs and labels - name: ObserveCatalog description: Catalog APIs x-group: Catalogs and labels - name: OpenAPI description: Downloadable API specification - name: ProjectOperationExecution description: Project-scoped operation history and pipeline health - name: ObserveClassification description: Flow and subflow classification APIs - name: ObserveIntegrationStats description: Integration stats APIs - name: ObserveTimeSeriesPrecalculation description: Time series precalculation APIs - name: ObserveIDList x-group: Saved ID lists description: Stored ID-list selection APIs - name: ObserveDataContext description: Schema-loose data context APIs for agent and debugging tooling - name: ObserveData description: Observe data administration APIs - name: ObserveTrackingStats description: Tracking ingestion stats APIs - name: ObserveExperiment x-group: Experiments description: Experiment catalog and run APIs - name: ObserveDataPolicy description: >- Project data policy catalogue (retention selected by the SDK's meta.dataPolicy code) - name: ObserveMetadata x-group: Metadata description: Authenticator metadata APIs (FIDO MDS + passkey AAGUID) - name: ObservePasskey x-group: Passkey analysis description: Observed passkey search and cohort analysis. paths: /observe/alertRuleTypes: get: tags: - ObserveAlert summary: List alert rule types description: >- Lists the alert rule types that can be created, described for the authenticated project.
