Comment github issues from Travis CI as TravisCIBot - github

In this tutorial someone describes how to use the GitHub REST API to create comments in pullrequests using GitHub's personal access tokens.
Finally, there appears a comment with your personal github account and avatar.
In the example one can see such a command with the text Test it at [...].
Is there an option to comment as traviscibot, such that this travis icon will show up instead? I want the reader to be able to distinguish which commands were made by Travis and which were made by a human.
A possible work-around would be to create a new GitHub account, name it my-travis-1234567890, add this account to the repository, create a personal access token for this account and use the latter. But is there a way without creating a new GitHub account?

How to create a comment with data from endpoint?

At my company, we have a CLI which allows our customers to upload data to our backend solution. The CLI runs on PR changes within a job. Let's assume the uploaded data looks like this:
{
name: "John",
age: 20,
}
Once the upload is completed, I'd like to create a comment on the PR with to following body:
John is 20 years old.
I've found the following ways to do this:
GitHub App (a bot)
GitHub OAuth App
Personal Access Token
GITHUB_TOKEN
GitHub App
The GitHub App needs to do the following things:
Fetch the data via a user-specific API key
Create a comment
I already created a comment via a bot, but I have no clue how to fetch the data.
As far as my understanding goes, I'd like other users to be able to install this GitHub app from the marketplace to work out of the box. From the ProBot Docs I understand that the bot operates on a webhook basis. Meaning I need to subscribe to a 'job completed' event (not sure if that's the correct name but I think you get the idea) and then fetch the data via a user-specific API we are providing on our platform. However, I see no way for the user of our App to configure an API key (or any form of secret) so the bot can make authenticated requests to our endpoints.
I'd prefer to use GitHub App because the comment coming from the bot would have our company branding and also an indicator that this comment has been created by the integration.
OAuth App
I already tested this by using Postman, however, the comment looks like it's coming from a specific user. Therefore, it has no company branding and it's not clear that an integration created the comment. However, the great part is that we could integrate this with our application, so our backend could create the comment once the data is received.
What I like about this approach is that we also need to implement such a feature for GitLab, Azure, etc, and using OAuth likely scales well with the other providers in comparison to the GitHub app, which is GitHub-specific.
Personal Access Token
Works pretty much like the OAuth App, but instead of our backend creating the comment, the comment is created by the CLI (and the access token is passed into the CLI). However, I think this approach is a bit sketchy.
GITHUB_TOKEN
While I haven't tried this yet, I assume that the token has limited but sufficient permissions to create a comment. As of now, I don't know what the comment will look like, but I think we can rather safely pass this into the CLI to create the comment from there. Since the permissions are limited and the token is invalidated after the workflow I see limited risk for the user of our CLI (and services).
Edit: The comment is coming from the github-actions bot, which is not the branding we are looking for, but it's clear that the comment has been created by the integration.
Questions
What's the best way to accomplish what I am trying?
Is there any way I can make this work with GitHub Apps (aka bots)?

Azure Devops SonarQube Pull Request Decoration

We have successfully integrated SonarQube into our build pipelines on Azure DevOps and have used a developer's account to generate a PAT for pull request decoration. The problem is now that the developer's account is posting comments across all our repos on different Pull Requests. It seems the alternative is to create a whole new user titled 'SonarQube' (or similar) in our Active Directory and generate a new PAT to do this, which seems overkill. Any alternative options would be appreciated.
Creating a separate identity that would belong to SonarQube is the only option. The identity posts the comments using the DevOps API where the PAT is the only identification of the identity.
Using a developer's account for PR decoration not only feels strange when reading the comments, but it is also fragile. When the developer leaves the company, their account will be terminated and suddenly, PR decoration will break and it may not be immediately clear why. Also, the developer could revoke the PAT at any time by mistake. In a larger organization, no single developer will have the right to comment on pull requests everywhere, so multiple developer accounts will be in use, which makes the configuration even more complex and fragile.

Can Personal Access Token with limited scope be shared with other users?

I'm building a CLI which triggers an Action (using workflow_dispatch) in my repository. I'm using Github API to perform this task. Taken from the docs:
You must authenticate using an access token with the repo scope to use this endpoint.
I've generated a PAT with repo scope to authenticate myself. I want users to run this CLI. Is it safe to share this PAT (which has repo as the only scope)?
p.s. I know it is ironical to ask if "Personal"-access-token can be "shared". But I don't see any problem it can cause with its limited scope.
I don't think it is a good idea. Repo scope is not limited to only one repo.
If you want to trigger actions by external users, your best bet would probably be to create a workflow running on PR or Issue events.
Allow your users to create issues
Monitor keywords or label on the issue
Trigger your action.

GitHub - best practice for authentication when automating organization account workflow

I am tasked to help automate the workflow related to automating a few tasks related to management of our organization account on GitHub. For example, add and remove users from the org, create new repos, add external collaborators etc. The requests for this actions will come from a system where a user fill in a form and this system will curl to the GitHub API after the request is reviewed and approved.
By reading the GitHub API documentation I can set up the curls for this, but I am unsure about authentication best practices. My first idea would be to create a user account specific for this use case, make it admin for the org, and create an OAuth token with scopes needed to be allowed to make this requests. However, it feels a bit too hacky to create an individual account for something that is not an individual, and then make it admin of the whole organization.
Is there a better way to approach this?

Github permissions

We've set up a Github app so that it automatically forks a repository for another individual Github user using the Github API. Now we're running into a problem that not everyone wants to give us full read access to all of their private repositories since sometimes they contain sensitive data.
Is there a way to only get read/write permission to a single repository and not the individual's entire account?
Unfortunately, this is not available yet. This feature is still under development as you can see in the Gihub Apps roadmap (and note that I am talking about Github Apps, not OAuth Github Apps). I don't know if this will ever be possible in OAuth Apps but it seems that it might in Github Apps.
There is already a discussion about this at the dear github repository. You should check for news there.
Is there a way to only get read/write permission to a single repository and not the individual's entire account?
Not that I know of: it is easier to setup a new dedicated GitHub account where you would recreate the private repos you want to give access to.
In that new account, you can consider all the private repos can be accessed.
You would keep the really private ones (with sensitive information) in your original GitHub account.
I believe you're looking for X-OAuth-Scopes. This is a well-defined header so that you may restrict your access scope to, for example, public repositories only.
The github developer documentation here says:
... space-delimited list of scopes. If not provided, scope defaults to an empty list for users that have not authorized any scopes for the application. For users who have authorized scopes for the application, the user won't be shown the OAuth authorization page with the list of scopes. Instead, this step of the flow will automatically complete with the set of scopes the user has authorized for the application. For example, if a user has already performed the web flow twice and has authorized one token with user scope and another token with repo scope, a third web flow that does not provide a scope will receive a token with user and repo scope.
