Once you have your API key, open the extension settings and input it

3.2 Explanation of each setting

There are two parameter configurations you can tweak during the resolution of the reCAPTCHA v2 and HCaptcha

  1. Delay between start solve captcha (ms):
  • This setting determines the time delay between starting the solving process for each captcha challenge.
  • It is measured in milliseconds (ms), and you can adjust the value based on your preference.
  • A higher delay can provide more time for the extension to process and solve the captcha, but it may increase the overall solving time.
  1. Repeat captcha solving in case of an error:
  • This setting controls whether the extension should automatically retry solving a captcha in case of an error during the initial attempt.
  • The number of repeat attempts may vary depending on the specific error encountered.

3.3 reCAPTCHA V3 setting

When you choose to solve reCAPTCHA v3, you can choose between different types of tasks

  • ReCaptchaV3TaskProxyLess: is using the server's built-in proxy.
  • ReCaptchaV3M1TaskProxyLess: built-in with high-quality proxies, the score can remain stable at 0.7 or above. If your target website requires a high score, it is recommended to choose this task.

3.4 Manual solving

The manual solving feature means that when the target website presents a Captcha, the extension will not automatically solve it. Users need to click the button next to the Captcha to initiate the resolution process.

3.5 How to Import proxy

Extension also allows users to pass in their own proxies, enable the proxy button and then pass your own proxy in the required format, And we support four formats of proxies: HTTP, HTTPS, SOCKS4, and SOCKS5.

3.7 How to use callback

Callback feature in the CapSolver extension, follow these steps:

  1. Configure the "Solved Callback" option in the pop-up window of the CapSolver extension (or in config.js). This option is the name of the callback function to be executed after the captcha is resolved, and it is captchaSolvedCallback by default.
  2. After opening the page, immediately mount the callback function to be executed to the window. The name of the mounted function is the "Solved Callback" configured in the previous step.
