+### VK Image
+
+<sup>[API method description.](https://2captcha.com/2captcha-api#vkcaptcha)</sup>
+
+We offer two methods to solve this type of captcha - token-based and image-based.
+
+We use the body (image in base64 format) or file (image as file) and steps parameters.
+You can get both values from the response to the request https://api.vk.com/method/captchaNotRobot.getContent?v={API_VER} when loading the captcha widget on the page.
+
+```csharp
+TwoCaptcha solver = new TwoCaptcha(apiKey);
+
+byte[] bytes = File.ReadAllBytes("resources/vk.jpg");
+string base64EncodedImage = Convert.ToBase64String(bytes);
+
+VkCaptcha captcha = new VkCaptcha("vkimage");
+captcha.SetBase64(base64EncodedImage);
+captcha.SetSteps("[5,12,22,24,21,23,10,7,2,8,19,18,8,24,21,22,11,14,16,5,18,20,4,21,12,6,0,0,11,12,8,20,19,3,14,8,9,13,16,24,18,3,2,23,8,12,6,1,11,0,20,15,19,22,17,24,8,0,12,5,19,14,11,6,7,14,23,24,23,20,4,20,6,12,4,17,4,18,6,20,17,5,23,7,10,2,8,9,5,4,17,24,11,14,4,10,12,22,21,2]");
+
+```
+
+### VK Captcha
+
+<sup>[API method description.](https://2captcha.com/2captcha-api#vk-captcha)</sup>
+
+Token-based method requires redirect_uri parameter, as well as proxy and userAgent. The value of the redirect_uri parameter can be found in the response to requests to the VK API that return captchas.
+
+```csharp
+VkCaptcha captcha = new VkCaptcha("vkcaptcha");
+
+captcha.SetRedirectUri("https://id.vk.com/not_robot_captcha?domain=vk.com&session_token=eyJ....HGsc5B4LyvjA&variant=popup&blank=1");
+captcha.SetuserAgent("Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/115.0.0.0 Safari/537.36");
+captcha.SetProxy("http", "1.2.3.4");
+```
