Set Variable Key and Type. Set Initial Value for a fresh node's starting value: this field disappears once Persist Value is on, since the last persisted value is used instead. The Name field shown in the card's Details section is a read-only echo of Variable Key, not a separate display name.
Enable Persist Value only when the last value should return after the workflow reloads. The card shows Current Value while the workflow runs.
Set Src and Dst to the number of source and destination ports to generate: each is a count from 2 to 200 (default 10), not a list of named entries. Set Lvls (1–10, default 1) to add that many sub-ports to every Src and Dst port, labeled A, B, C, and so on.
The card lists one row per port: an input handle labeled Src *N on the left (or A Src *N*, B Src *N*, and so on per level) and an output handle labeled Dst *N* (or **Dst *NA, *Dst *NB, and so on) on the right.
The generated ports appear in Buttons routing views (for example Routing → Ports) under a Connection entry named after this workflow, with each port's User Label following the same Src *N* / Dst *N* pattern: confirmed live, no naming controls exist for them beyond the port count.
Use this node when a workflow value must participate in routing. Use normal workflow connections when the value stays inside one workflow.
Feed a workflow-generated value into a Src handle to publish it as a routable source, then route it to a Dst handle elsewhere (on this workflow or another) to deliver it as an output. Build the actual route from the Routing views, not from this node.
The card only shows the options you've already added, as output handles: Title, Description, and Add Option aren't on the card. Select the node to open its Configuration panel, which is where this node is actually built:
Set an optional Title to identify this action wherever it can be triggered from, and a Description shown alongside it there.
Use Add Option to define a typed input the caller fills in: Text, Number, True/False, Dropdown, or Multi Dropdown. Each option gets a Label and a Default value; Dropdown and Multi Dropdown also need a list of choices, each with an ID and a Value.
Every configured option appears as its own output handle on the card, carrying the value supplied the last time the action ran. States outputs every option's value together as one object, Timestamp outputs when it last ran, and Event fires each time it runs. All outputs are empty until the action has run at least once.
Trigger this node from outside its own workflow using the Trigger Workflow Action action, available on button and other control actions and from other workflows' Internal Action node: choose the Workflow, then this node by its Title, then fill in the same options configured here.
Add a Workflow Action with a Dropdown option named Mode, then trigger it from a button's Trigger Workflow Action action to switch the workflow's behavior from outside it.
