When I give the API Token value in my project and try to send it to github, I get an error

 Hi Yalçın Mete,

Thank you for reaching out to Microsoft Q & A forum.

The error you’re experiencing may be related to GitHub’s security policies, which actively scan repositories for sensitive information, such as API tokens. If GitHub detects sensitive data, it may block the push to prevent accidental exposure. 

To address this issue, here are a few recommendations: 

1.Remove the API Key from your source code: Instead of hardcoding the API key into your project files, consider storing it securely using environment variables or a secrets management tool. In .NET Core, for example, you can store sensitive data in appsettings.json for local development and use environment variables in production. 

2.Add sensitive files to .gitignore: To prevent committing files with sensitive information, ensure that such files (like appsettings.json) are listed in the .gitignore file so they won’t be tracked or pushed to GitHub. 

3.Review GitHub’s Secret Scanning: GitHub may have detected the API key and blocked the push as a security measure. You can check the Security tab in your GitHub repository for any alerts or warnings related to this. 

Additionally, you can review the output window in Visual Studio for more detailed error messages. Here’s a guide from Microsoft on pushing to a remote Git repository using Visual Studio: Git push to remote repository in Visual Studio. 

If the issue persists after these steps, please provide the error message from the output window, as this will help me give you more specific assistance.
