Input blocks
| Block | What it does | Key configuration |
|---|---|---|
| Form | A multi-field form. Submitting it starts a workflow run from the form node, with the entered values on the node’s output. | Form Fields: each field has a name (used in references), type (string, number, boolean, object, array, select, credential), label, description, required flag, and options for select fields. |
| Config Form | A persistent settings form. Values are saved with the workflow and output on every run, so downstream nodes can reference them as {{node-id.values.field_name}}. Unlike Form, it stores values instead of starting runs. | Fields: name, type (string, number, boolean, select, schedule, list), label, description, required flag, options, and a default value. |

There is one more block that never appears in the palette: Agent Chat. Enable Show in Interface on an AI agent node (or click the Chat pill on the node) and the agent appears as a fullscreen chat tab in the Interface tab. See AI agents.
