SonarQube+Gitlab api authentication yml 401

Question

I have a personal SonarQube (Latest LTS) and Gitlab (14.5.1) installation. I've set-up everything and login with Gitlab through the web interface is working. However, I'm looking for a way to login with gitlab credentials throught the SonarQube API. If I add this to my gitlab-ci.yml file: https://sonarqube.example.com/api/projects/create?name=testProject I get a 401 (which is expected since I haven't added an API key and such).

My question is: Is it possible to automatically create an API key, use it in the gitlab-ci.yml and authenticate with it? If there's no way of doing this, is there an possibility to generate a group API key so that users in a certain group have access to the API, both on SonarQube and Gitlab?

Have been stuck on this for a while now, thanks in advance.

On the official documentation there are a set of steps for Auth for GitLab

Authenticating with GitLab

You can delegate authentication to GitLab using a dedicated GitLab OAuth application.

Creating a GitLab OAuth app You can find general instructions for creating a GitLab OAuth app here.

Specify the following settings in your OAuth app:

• Name – your app's name, such as SonarQube.

• Redirect URI – enter your SonarQube URL with the path /oauth2/callback/gitlab. For example, https://sonarqube.mycompany.com/oauth2/callback/gitlab.

• Scopes – select api if you plan to enable group synchronization. Select read_user if you only plan to delegate authentication.
