As you may know our API for reCaptcha v2 requires a URL<\/strong>, a Sitekey<\/strong> and optionally a proxy<\/strong>, we will guide you on how to perform the whole captcha solving process and then show you how to use the token produced in a POST request to submit the form.<\/p>\n

We will start our test<\/strong> with the URL:<\/p>\n

\"\"<\/p>\n

This is a reCaptcha v2 demo<\/strong> page and it will simulate the Website<\/strong> which contains the reCatcha you want to solve. You already have the URL now we need to get the Sitekey<\/strong>.<\/p>\n

\"\"<\/p>\n

There are two ways<\/strong> to obtain the Sitekey, the first one is finding the \u201cdata-sitekey\u201d<\/strong> tag in the HTML of the page. The second one is finding the \u201ciframe\u201d<\/strong> tag. We will see how to find it both ways.<\/p>\n

First step is using the built-in \u201cInspect Element\u201d<\/strong> feature of your browser. Then find the \u201cdata-sitekey\u201d<\/strong> tag or the \u201ciframe\u201d<\/strong> tag, (there could be several in one site, make sure you are accessing the one for the reCaptcha), right click on it an select \u201cEdit as HTML\u201d<\/strong> after you\u2019ve done it you will be able to extract the Sitekey from it, follow the example in the pictures.<\/p>\n

\"\"<\/p>\n

a) Find iFrame tag<\/p>\n

\"\"<\/p>\n

b) Copy the Sitekey<\/p>\n

\"\"<\/p>\n

Now, you\u2019ve found your Sitekey and URL, it\u2019s time to save your parameters as a JSON file<\/strong>. If you are not using a proxy you can leave \u201cproxy\u201d and \u201cproxytype\u201d parameters empty as in the example.<\/p>\n

\"\"<\/p>\n

It\u2019s now time to make your API call; first make a POST<\/strong> request to the URL \u2018https:\/\/api.dbcapi.me\/api\/captcha<\/strong>\u2019 using your username<\/strong>, password<\/strong>, captcha type<\/strong> and recently created \u201cparams.json<\/strong><\/em>\u201d file, finally send the request.<\/p>\n

\"\"<\/p>\n

Now, you can find the response in your Previous Submissions<\/strong> page: https:\/\/deathbycaptcha.com\/user\/captchas<\/p>\n

\"\"<\/p>\n

\"\"<\/p>\n

Copy the text received and it’s time to make a second API request to submit the form of the website.<\/p>\n

The request needs to be a POST<\/strong> request with the fields name as parameters as well as the reCaptcha box ID, named g-recaptcha-response<\/strong> (which will accept the token produced by our API). That request needs to be made to the same URL<\/strong> that appears in the ‘action<\/strong>‘ attribute of the form.<\/p>\n

    \n
  1. URL:<\/strong><\/li>\n<\/ol>\n

    \"\"<\/p>\n

    2. Form fields name<\/strong><\/p>\n

    \"\"<\/p>\n

    3. ReCaptcha text field ID<\/strong><\/p>\n

    \"\"<\/p>\n

    And that’s it!<\/strong> That’s all which is required to start your API call and finally submit the form. Simply paste the token as the value for g-recaptcha-response<\/strong> and hit send.<\/p>\n
