Flavours not belonging to the project are ignored. An error never mixes subflow types: the assigned flavours must share one subflow type, which must match the error's stamped scope (stamped on first assignment, cleared when the last member is unassigned or moved away). Violations return a validation error. Required API key permission: `observe:errorFlavours:write`. ## OpenAPI ````yaml /api-reference/openapi/observe.yaml patch /observe/errorFlavours 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/errorFlavours: patch: tags: - ObserveErrorFlavour summary: Assign error flavours description: >- Bulk-assigns the given error flavours to an error (or unassigns them when errorID is omitted).
