        .getAttribute("src")
).get("k")

Prepare task​

We get the site key, we already got the url. Lets create the task!

import { RecaptchaV2EnterpriseTask } from "node-capmonster"

const client = new RecaptchaV2EnterpriseTask("<api_key>")
const task = client.task({
    websiteKey: "<website_key>",
    websiteURL: "<url>",
})

Create solving request​

// other codes..
const taskId = await client.createWithTask(task)

Get the response​

// other codes..
const result = await client.getTaskResult(taskId) // get the result
if (result !== null) {
    // check the result
    console.log(result.text)
}
warning

In this case, getTaskResult function can be return null. You have to check the result before using. Or you can use joinTaskResult function.

with joinTaskResult​

// other codes..
const result = await client.joinTaskResult(taskId)
console.log(result.text)
