Code of Conduct

• I have read and agree to the GitHub Docs project's Code of Conduct

What article on docs.github.com is affected?

https://docs.github.com/en/actions/migrating-to-github-actions/automated-migrations/migrating-from-circleci-with-github-actions-importer#configuring-credentials

What part(s) of the article would you like to see updated?

Create a GitHub personal access token (classic). For more information, see "Managing your personal access tokens."

Your token must have the workflow scope.

After creating the token, copy it and save it in a safe location for later use.

https://docs.github.com/en/actions/migrating-to-github-actions/automated-migrations/migrating-from-circleci-with-github-actions-importer#using-environment-variables

GitHub Actions Importer uses the following environment variables to connect to your CircleCI instance:

GITHUB_ACCESS_TOKEN: The personal access token (classic) used to create pull requests with a converted workflow (requires repo and workflow scopes).

Additional information

It's possible these sections aren't talking about the same thing, but that feels unlikely, and as I've tripped on an error that seems related, it feels like a bug.

[github-actions]

Thanks for opening an issue! We've triaged this issue for technical review by a subject matter expert 👀

@jsoref Thank you for your patience while our SME team reviewed! They wanted to relay the following -

We need both perms, thank you for helping clean up our docs!

We need both perms for the following reasons:

• Workflow Permission: Required to create and update GitHub Actions workflows using GitHub Actions Integration (GAI).
• Repo Permission: Necessary to open a pull request against the repository that includes the new workflow created with GAI.

I've added the help wanted label so that you, or anyone else, can raise a PR to update the doc to state both permissions are needed 💛
