+### VKCaptcha
+
+<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.
+
+```go
+vkcaptcha := api2captcha.VKCaptcha{
+   Base64:     "/9j/4AAQSkZJRgABAQAAAQABAAD/2wB...",
+   Steps:      "[5,19,14,14,6,4,8,9...]
+}
