Check
The check step sets a checkbox or radio button to checked. It is idempotent: if the control is already checked, nothing changes and the run continues.
In a workflow, this is a step object with "type": "check". Steps run in order, and each step can read the outputs of the steps before it. See the fullworkflows reference for the 30+ step types.
Writ runs on your own accounts, with your own credentials and data, on sites you are authorized to use.
Fields
| Field | Type | Description |
|---|---|---|
selectorrequired | selector | The checkbox or radio input. |
Example
A single check step as it appears in a workflow's steps array:
{
"type": "check",
"config": { "selector": "#agree-to-terms" }
}How it behaves
- Idempotent: safe to run even if the box is already checked.
- uncheck is the mirror step for clearing a checkbox.
Where it runs
The check step executes wherever the run executes. On yourlocal or BYO agent there is no compute charge and the agent can reach intranet-only systems; on Writ cloud the run is metered by running time (~$0.12 per browser-hour, from your plan’s included usagewallet.
