The settings are the same as for connecting Grafana, without a token, and are checked the same way: the connection is refused when the token cannot read metrics or host metrics cannot be read. Nothing changes when the check fails. On success metrics is added to the connection's connection_modes and cost stays on. ## OpenAPI ````yaml /api-reference/costgraph/openapi.json post /api/v1/integrations/grafana/from-connection/{id} openapi: 3.0.0 info: description: Read and manage your CostGraph organization, spend, alerts, and settings. title: CostGraph API contact: {} version: '1.0' servers: - url: https://api.costgraph.ai security: [] tags: - name: ai x-group: AI - name: ai-serving x-group: AI serving - name: anomalies x-group: Anomalies - name: auth x-group: Auth - name: billing x-group: Billing - name: billing-export x-group: Billing export - name: budgets x-group: Budgets - name: ci x-group: CI - name: compute-recommendations x-group: Compute recommendations - name: config x-group: Config - name: context-graph x-group: Context graph - name: cost x-group: Cost - name: gpus x-group: GPUs - name: graphai x-group: Graph AI - name: integrations x-group: Integrations - name: invitations x-group: Invitations - name: kubernetes-clusters x-group: Kubernetes clusters - name: marketplace x-group: Marketplace - name: network-requests x-group: Network requests - name: notifications x-group: Notifications - name: oauth x-group: OAuth - name: oauth-clients x-group: OAuth clients - name: opencost x-group: OpenCost - name: organization x-group: Audit log - name: organizations x-group: Organizations - name: placement-alternatives x-group: Placement alternatives - name: reports x-group: Reports - name: service-map x-group: Service map - name: settings x-group: Settings - name: sso x-group: Single sign-on - name: tenants x-group: Tenants - name: ticketing x-group: Ticketing - name: user x-group: Users - name: virtual-machines x-group: Virtual machines - name: virtual-tags x-group: Virtual tags - name: workflows x-group: Workflows paths: /api/v1/integrations/grafana/from-connection/{id}: post: tags: - integrations summary: Use a Grafana Cloud cost connection for metrics description: >- Lets an existing Grafana Cloud cost connection also serve Mac metrics, reusing the token stored with it, so no second token is entered.
