Button with click validation

If a task requires a performer to click a link (for example, to open a webpage), Toloka can check if the performer did it. The link is displayed in the task as a button.

Variations of button use:

• Checking if the user opened a link. The output data will contain a field with values true (the performer opened the link) or false (the performer didn't open the link).

• Preventing the user from completing the task if the link was not opened. Add the "allowed_values":[true] parameter in the output data description.

To add the button with the link to the task interface, use the {{field type="button-clicked" name="output field name>"}} component. Example:

{{field type="button-clicked" name="ads" label="Click me" href="https://yandex.ru" action=true}}

For a complete list of parameters, see the table.

Add a field of Boolean type to the output data description. To prevent the user from sending responses without opening the link, add the "allowed_values":[true] parameter.

{
  "ads": {
    "type": "boolean",
    "required": true,
    "allowed_values": [true]
  }
}
