Fetching gitlab repo list : says "401 Unauthorized"

I am trying to get repo list from gitlab using OAuth token.

My code looks something like this ... ("github.com/xanzy/go-gitlab")

    repositories := []string{}
    client, _ := gitlab.NewClient(gitRepoRequest.Token, gitlab.WithBaseURL("https://gitlab.com/api/v4"))
    fmt.Println("client...", client.ContainerRegistry)

    projects, _, projectListErr := client.Projects.ListProjects(&gitlab.ListProjectsOptions{})
    for _, project := range projects {
        fmt.Println("ID===", project.ID)
        fmt.Println("NAME===", project.Name)
    }

    if projectListErr != nil {
        // return err
    }

I am not able to get the project list.. the "projectListErr" says ... GET https://gitlab.com/api/v4/projects: 401 {message: 401 Unauthorized}

I am confident about the token value because I am getting list of all branches for a repo using the same token, that code looks like ... ("github.com/go-git/go-git/v5")

rem := git.NewRemote(gitMemory.NewStorage(), &gitConfig.RemoteConfig{
    Name: "origin",
    URLs: []string{gitBranchesRequest.Repository},
})

refs, listErr := rem.List(&git.ListOptions{
    Auth: &gitHttp.BasicAuth{Username: gitUserName, Password: gitBranchesRequest.Token},
})

Does that mean there is an issue with the library that I am using ? github.com/xanzy/go-gitlab

gitlab go oauth

It depends on the type of token you are using.

For instance, a project access token might very well give you access to the list of all branches for a repository (for that project).

But for using the /projects API, 401 means the authentication information is not valid or is missing.

So make sure to use a PAT (Personal Access Token), linked to a user, not a project.

The OP Keval Bhogayata adds in the comments:

I have found the issue.

The library I am using ("xanzy/go-gitlab"), has different client creation functions for different tokens.

I have been using the function that supports personal access token. Instead I was supposed to use "NewOAuthClient" !

// NewOAuthClient returns a new GitLab API client. To use API methods which
// require authentication, provide a valid oauth token.
func NewOAuthClient(token string, options ...ClientOptionFunc) (*Client, error)
