Geetest Task

This task type is used to solve GeeTest captchas, including slider, icon, and other variants. The solution provides a complex object with validation data.

How to Use the Solution

You must submit all the fields from the `solution` object (e.g., `captcha_id`, `lot_number`, `pass_token`) along with your target form. These are usually placed in hidden input fields.

Proxy is Required

This task type requires a proxy. The proxy's IP must be used for both the solving task and your subsequent requests to the target website.

1. Create Task

Use the `createTask` method to initiate the solving process. You must provide the `websiteURL`, the GeeTest `captchaId`, and a `proxy`.

Task Object Parameters

PropertyTypeRequiredDescription
typeStringRequiredMust be `GeeTestTask`
websiteURLStringRequiredThe full URL of the page where the GeeTest captcha is present.
captchaIdStringRequiredThe `gt` or `captcha_id` public key for the GeeTest instance.
proxyStringRequiredYour proxy address in the format `http:login:password@ip:port`.
geetestApiServerSubdomainStringOptionalOptional. A custom subdomain for the GeeTest API if one is used by the target site.

Run Sandbox Task

2. Get Result

After creating a task, use the `getTaskResult` method to check the status and retrieve the solution. Poll this endpoint every 5-10 seconds until the status is `completed`.
