Loads a persistent variable into the pipeline. Values survive across individual runs — unlike transient trigger payload data.
When to use
- Read shared config (
{{$var.apiUrl}}keys) at runtime. - Load last-processed timestamp or counter state.
- Provide defaults when a key does not exist yet.
Properties
| Property | Type | Description |
|---|---|---|
| Scope | select | This workflow only or Global (shared across all workflows). |
| Variable Key | text | Key name, e.g. last_sensor_value. Required. |
| Default Value (when key does not exist) | text | Returned when key is missing; exists output is false. |
Outputs
| Field | Description |
|---|---|
value | Stored string or default. |
exists | True if key was found. |
key | Key that was read. |
Placeholders
In other node settings use {{$var.key}} for inline resolution. Global scope takes precedence over workflow scope when both exist.
