How to Implement GraphQL Authentication in Go

Use the GOAUTH environment variable to configure authentication commands for Go module downloads. Set GOAUTH to a command that outputs HTTP headers containing your credentials, such as GOAUTH=git /path/to/repo to use Git credentials or GOAUTH=netrc to use your .netrc file. The Go toolchain will execute this command when fetching modules from private repositories and inject the returned headers into the request.

Go uses the GOAUTH setting to securely fetch code from private servers. You tell Go how to get your password or token by setting this variable to a command like git or netrc. It's like giving Go a key to unlock the door to your private code before it tries to download it.
