``` {% endcode %} This is almost the same response you would receive with a Slider challenge, however the reference to this URL: `https://ct.captcha-delivery.com/i.js` is unique to interstitial. ### Parsing the HTML Before we explain how you can manually parse the required values from the HTML posted above, first are shown code snippets of how it can be done easily with our SDKs: {% tabs %} {% tab title="Golang" %}// reader is an `io.Reader` which holds the response body of the HTML.
// datadomeCookie is the cookie value of the cookie with name "datadome",
// this cookie is set by the 403 block page.
// referer is the URL that served the 403 block page.
deviceLink, err := datadome.ParseInterstitialDeviceCheckLink(reader, datadomeCookie, referer)
if err != nil {
// Handle the error
}
// deviceLink will look like: https://geo.captcha-delivery.com/interstitial/?...

Make sure that you are sending the same headers and in the same order as your browser. Read and save the response body of this request as we need it to submit to the Hyper Solutions API. ### Fetching the slider puzzle In order for the Hyper Solutions API to solve the slider challenge, it needs access to the images involved. The HTML that we have retrieved in the previous step contains links like these: {% code overflow="wrap" %} ```html ``` {% endcode %} It is up to you how you want to parse it, however here are two regex expressions that you can use: {% code title="Finding the puzzle link" %} ```regex (https:\/\/dd\.prod\.captcha-delivery\.com\/image\/.*?\.jpg) ``` {% endcode %} {% code title="Parsing the piece link" overflow="wrap" %} ```regex (https:\/\/dd\.prod\.captcha-delivery\.com\/image\/.*?\.frag.png) ``` {% endcode %} You need to make a GET request to both links and store both responses (base64 encoded) as the `puzzle` for the jpg and as `piece` for the png. {% hint style="info" %} The requests to these images are not required to be made by a TLS client, as there are no cookies involved. If you are struggling with making this request with your TLS client, just use your favorite HTTP client instead. {% endhint %} ### Fetching the payload from API Again we have handy SDK functions to help you with these API calls, if you want to implement the API calls yourself, head over to the [API Reference](https://docs.hypersolutions.co/api-reference/datadome).\ \ There are 5 values that you need for these API calls: * userAgent: Your browser's User-Agent. * deviceLink: The link we have parsed in one of the previous sections. * html: The full response contents of the GET request you made to the deviceLink URL. * puzzle: The base64 encoded response bytes from the jpg image. * piece: The base64 encoded response bytes from the `.frag.png` image. You can then generate the payload with the SDK as follows: {% tabs %} {% tab title="Golang" %} {% code overflow="wrap" %} ```go checkUrl, err := session.GenerateDataDomeSlider(ctx, &hyper.DataDomeSliderInput{ // Set the required input fields }) if err != nil { // Handle the error } // Create a GET request to the checkUrl ``` {% endcode %} {% endtab %} {% tab title="Python" %} {% code overflow="wrap" %} ```python payload = hyper_session.generate_slider_payload(hyper_sdk.DataDomeSliderInput( user_agent=USER_AGENT, device_link=device_check_link, html=html_content, puzzle=base64_encoded_puzzle, piece=base64_encoded_piece )) # Create a GET request to the payload URL ``` {% endcode %} {% endtab %} {% tab title="JS / TS" %} {% code overflow="wrap" %} ```javascript // Response body from doing a GET request to result.url const deviceCheckBody = ""; const payload = await generateSliderPayload(session, { userAgent: "", // Browser user agent to impersonate deviceLink: result.url, html: deviceCheckBody, puzzle: "", // Puzzle image bytes, base64 encoded (looks like: `https://dd.prod.captcha-delivery.com/image/2024-xx-xx/hash.jpg`) piece: "" // Piece image bytes, base64 encoded (looks like: `https://dd.prod.captcha-delivery.com/image/2024-xx-xx/hash.frag.png`) }); ``` {% endcode %} {% endtab %} {% endtabs %} ### Posting payload, solving challenge Our API returns a simple URL as the result of solving the slider challenge, all that is required is to make a GET request to this URL which looks as follows: ``` https://geo.captcha-delivery.com/captcha/check?cid=... ``` The response of this GET request will be as follows: {% code overflow="wrap" %} ```json { "cookie": "datadome=cookievalue; Max-Age=31536000; Domain=.example.com; Path=/; Secure; SameSite=Lax" } ``` {% endcode %} You can parse the JSON response, and update your cookieJar with the `"cookie"` you received from DataDome.\ \ You have now successfully solved DataDome's slider challenge, retrying the request that served this block should not give you a challenge anymore. ## Complete Example For a full working implementation with proper TLS client setup, header ordering, and cookie handling, see our examples repository: {% embed url="
