A `dashboardAPI` node converts EVOLV node topology into Grafana dashboards. On each inbound `child.register` event it resolves the child source, walks its direct children, loads per-`softwareType` Grafana JSON templates from `config/`, and emits one HTTP upsert request per dashboard on Port 0 to a downstream `http request` node. Sits adjacent to the S88 hierarchy as a passive HTTP emitter — **no measurements, no tick loop, no parent registration**.
Dashed arrows = inbound `child.register` events from any EVOLV process node. The solid arrow is the outbound HTTP upsert envelope on Port 0 — emitted **once per generated dashboard** in the walked graph. S88 colours and the utility-neutral `#dddddd` are anchored in `.claude/rules/node-red-flow-layout.md`.
1. Open the inject node (`basic trigger`) and edit the payload to a `{source: {config: {...}}}` shape — see [Reference — Examples](Reference-Examples#wiring-pattern) for the minimal inline-payload shape.
2. Fire the inject. Watch the debug pane: one `topic: 'create'` HTTP envelope appears per dashboard in the walked graph (root + direct children).
3. Wire a downstream `http request` node (method `POST`) to the dashboardAPI output to actually POST the envelope to Grafana.
> The shipped `basic.flow.json` / `integration.flow.json` / `edge.flow.json` are stubs — the inject payloads do not yet conform to the `child.register` resolver's expected shape. They will trigger `Missing or invalid child node` errors until updated. Tracked in [Limitations — Example flow stubs](Reference-Limitations#example-flow-stubs).
That's it. There is no `set.*`, no `cmd.*`, no `query.*` — the registry has a single canonical topic (alias-with-deprecation). The legacy `registerChild` alias logs a one-time deprecation warning on first use.
> Port 1 (InfluxDB telemetry) and Port 2 (registration / control plumbing) are **unused** — dashboardAPI has no measurements and does not register with a parent. See [Reference — Architecture](Reference-Architecture#output-ports).
Most EVOLV nodes extend `BaseNodeAdapter` + `BaseDomain` from `generalFunctions/`. `dashboardAPI` does **not** — per `OPEN_QUESTIONS.md` (2026-05-10) the decision is to keep a bespoke adapter until `BaseNodeAdapter` grows passive / HTTP-only flags.
- No `generalFunctions/src/configs/dashboardapi.json` — `BaseDomain`'s constructor unconditionally calls `configManager.getConfig(ctor.name)` and would throw. The local `dependencies/dashboardapi/dashboardapiConfig.json` is for the editor menu endpoint, not the runtime config pipeline.
- No periodic output — `BaseNodeAdapter._emitOutputs()` / `outputUtils.formatMsg` assumes a delta-compressed Port 0 / 1 stream; dashboardAPI emits HTTP-shaped messages instead.
- No registration to a parent — `BaseNodeAdapter._scheduleRegistration` would emit a spurious `child.register` of its own.
- No status badge / tick / measurements / children of its own.
dashboardAPI uses the shared `commandRegistry` (canonical-topic naming + alias-with-deprecation) and stops there. See [Reference — Architecture](Reference-Architecture#why-no-basenodeadapter--basedomain) for the full rationale.
