You need to use an API token to connect to Discord using a script. You can obtain this token by creating a Discord bot application and adding it to your server.
Once you have the API token, you can use a Discord API library for your programming language to connect to Discord. These libraries usually have functions for logging in with the API token and sending messages to channels.
Regarding the captcha verification, you can use a headless browser like Selenium to automate the captcha-solving process. This involves simulating a user's actions to solve the captcha and then continuing with the script. Configuring it that way is not easy.
However, it's important to note that Discord's terms of service prohibit using automated scripts to access their platform. So make sure to use the API and any automation tools in compliance with their policies.
