Cloudflare: solving Turnstile

TIP

Create the task with the createTask method and get the result with the getTaskResult method.

DANGER

ℹ️turnstile type doesn’t require proxy, so you just use AntiTurnstileTaskProxyLess

The Turnstile/Challenge verification code is another attempt to replace reCaptcha/hCaptcha. We automatically support these subtypes:

turnstile
- Manually
- Non-Interactive
- InVisible
challenge
- 5s challenge
- Non-Interactive turnstile

There is no need to specify subtypes during your call. It is not necessary to provide your own custom User-Agent yet, we will ignore this parameter.

Type	Note	State
	turnstile	stable

The task type type is as follows

AntiTurnstileTaskProxyLess

Create Task

Create the task with the createTask.

In the process of using turnstile, we must input websiteURL and websiteKey, other parameters are optional.

Task Object Structure

Properties	Type	Required	Description
type	String	Required	`AntiTurnstileTaskProxyLess`
websiteURL	String	Required	The address of the target page.
websiteKey	String	Required	Turnstile website key.
metadata	`Map<String,String>`	Optional	Turnstile extra data . Turnstile Documentation
metadata.action	String	Optional	The value of the `data-action` attribute of the Turnstile element if it exists.
metadata.cdata	String	Optional	The value of the `data-cdata` attribute of the Turnstile element if it exists.

Example Request

POST https://api.capsolver.com/createTask
Host: api.capsolver.com
Content-Type: application/json

{
  "clientKey": "YOUR_API_KEY",
  "task": {
    "type": "AntiTurnstileTaskProxyLess",
    "websiteURL": "https://www.yourwebsite.com",
    "websiteKey": "0x4XXXXXXXXXXXXXXXXX",
    "metadata": {
       "action": "login",  //optional
       "cdata": "0000-1111-2222-3333-example-cdata"  //optional
    }
  }
}

Example Response

{
  "errorId": 0,
  "status": "idle",
  "taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006"   // record taskId
}

Getting Result

Use the getTaskResult method to get the recognition results

Depending on the system load, you will get the results within the interval of 1s to 20s

Example Request

POST https://api.capsolver.com/getTaskResult
Host: api.capsolver.com
Content-Type: application/json

{
  "clientKey": "YOUR_API_KEY",
  "taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006"
}

Example Response

{
  "errorId": 0,
  "taskId": "61138bb6-19fb-11ec-a9c8-0242ac110006",
  "status": "ready",
  "errorCode": null,
