Task creation object

Property Type Required Purpose
type String Yes AltchaTaskProxyless
websiteURL String Yes Address of a target web page. Can be located anywhere on the web site, even in a member area. Our workers don't navigate there but simulate the visit instead.
challengeURL String No Option 1: Challenge URL from altcha-widget

<altcha-widget challengeurl="/this/one"></altcha-widget >
challengeJSON String No Option 2: Challenge JSON fetched from challenge URL of the widget

Task solution object

Property Type Purpose
token String Token string required for interacting with the submit form on the destination page.
userAgent String User-Agent of the worker's browser. Use may want to use it when you submit the response token.
