This JavaScript GitHub Action can be used to impersonate a GitHub App when secrets.GITHUB_TOKEN's limitations are too restrictive and a personal access token is not suitable.

For instance, from GitHub Actions' docs:

When you use the repository's GITHUB_TOKEN to perform tasks, events triggered by the GITHUB_TOKEN, with the exception of workflow_dispatch and repository_dispatch, will not create a new workflow run. This prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository's GITHUB_TOKEN, a new workflow will not run even when the repository contains a workflow configured to run when push events occur.

A workaround is to use a personal access token from a personal user/bot account. However, for organizations, GitHub Apps are a more appropriate automation solution.

jobs: job: runs-on: ubuntu-latest steps: - id: create_token uses: tibdex/github-app-token@v2 with: app_id: ${{ secrets.APP_ID }} # Optional. # github_api_url: https://api.example.com # Optional. # installation_retrieval_mode: id # Optional. # installation_retrieval_payload: 1337 # Optional. # Using a YAML multiline string to avoid escaping the JSON quotes. # permissions: >- # {"pull_requests": "read"} private_key: ${{ secrets.PRIVATE_KEY }} # Optional. # repositories: >- # ["actions/toolkit", "github/docs"] # Optional. # revoke: false - run: "echo 'The created token is masked: ${{ steps.create_token.outputs.token }}'"

Another use case for this action can (or could) be found in GitHub's own docs.
