💡 Result:

<search_synthesis>
To successfully use the gh pr merge --auto command within a GitHub Actions workflow using the default GITHUB_TOKEN, you must explicitly configure the necessary permissions in your workflow file [1][2]. For the GITHUB_TOKEN to have sufficient access to enable auto-merge, the workflow job must be granted write access to pull requests and contents [1][2]. You can configure this using the permissions key within your workflow or job definition [2]. Recommended permission configuration: permissions: contents: write pull-requests: write Usage Example: jobs: auto-merge: runs-on: ubuntu-latest permissions: contents: write pull-requests: write steps: - name: Enable auto-merge env: GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} PR_URL: ${{ github.event.pull_request.html_url }} run: gh pr merge --auto --merge "$PR_URL" Important Considerations: - Repository Settings: The auto-merge feature must be enabled in your repository&#39;s general settings (under Pull Requests) for the command to function [3][4]. - Merge Queues: If your repository uses a merge queue, the default GITHUB_TOKEN cannot add pull requests to the queue [1]. In this specific scenario, you must use a Personal Access Token (PAT) or a GitHub App installation access token with appropriate permissions instead of the GITHUB_TOKEN [1][5]. - Least Privilege: As a security best practice, explicitly define only the permissions required for your workflow rather than relying on default permissions [2][5].

This tutorial leads you through how to use the `GITHUB_TOKEN` for authentication in GitHub Actions workflows, including examples for passing the token to actions, making API requests, and configuring permissions for secure automation. For reference information, see Workflow syntax for GitHub Actions. ## Using the `GITHUB_TOKEN` in a workflow You can use the `GITHUB_TOKEN` by using the standard syntax for referencing secrets: `${{ secrets.GITHUB_TOKEN }}`. Examples of using the `GITHUB_TOKEN` include passing the token as an input to an action, or using it to make an authenticated GitHub API request. > [!IMPORTANT] > An action can access the `GITHUB_TOKEN` through the `github.token` context even if the workflow does not explicitly pass the `GITHUB_TOKEN` to the action. As a good security practice, you should always make sure that actions only have the minimum access they require by limiting the permissions granted to the `GITHUB_TOKEN`. For more information, see Workflow syntax for GitHub Actions. ### Example 1: passing the `GITHUB_TOKEN` as an input This example workflow uses the GitHub CLI, which requires the `GITHUB_TOKEN` as the value for the `GH_TOKEN` input parameter: ```yaml copy name: Open new issue on: workflow_dispatch jobs: open-issue: runs-on: ubuntu-latest permissions: contents: read issues: write steps: - run: | gh issue --repo ${{ github.repository }} \ create --title "Issue title" --body "Issue body" env: GH_TOKEN: ${{ secrets.GITHUB_TOKEN }} ``` ### Example 2: calling the REST API You can use the `GITHUB_TOKEN` to make authenticated API calls. This example workflow creates an issue using the GitHub REST API: ```yaml name: Create issue on commit on: [ push ] jobs: create_issue: runs-on: ubuntu-latest permissions: issues: write steps: - name: Create issue using REST API run: | curl --request POST \ --url https://api.github.com/repos/${{ github.repository }}/issues \ --header &`#39`;authorization: Bearer ${{ secrets.GITHUB_TOKEN }}&`#39`; \ --header &`#39`;content-type: application/json&`#39`; \ --data &`#39`;{ "title": "Automated issue for commit: ${{ github.sha }}", "body": "This issue was automatically created by the GitHub Action workflow **${{ github.workflow }}**. \n\n The commit hash was: _${{ github.sha }}_." }&`#39`; \ --fail ``` ## Modifying the permissions for the `GITHUB_TOKEN` Use the `permissions` key in your workflow file to modify permissions for the `GITHUB_TOKEN` for an entire workflow or for individual jobs. This allows you to configure the minimum required permissions for a workflow or job. As a good security practice, you should grant the `GITHUB_TOKEN` the least required access. To see the list of permissions available for use and their parameterized names, see Managing your personal access tokens. The two workflow examples earlier in this article show the `permissions` key being used at the job level. ## Granting additional permissions If you need a token that requires permissions that aren&`#39`;t available in the `GITHUB_TOKEN`, create a GitHub App and generate an installation access token within your workflow. For more information, see Making authenticated API requests with a GitHub App in a GitHub Actions workflow. Alternatively, you can create a personal access token, store it as a secret in your repository, and use the token in your workflow with the `${{ secrets.SECRET_NAME }}` syntax. For more information, see Managing your personal access tokens and Using secrets in GitHub Actions. ## Next steps - GITHUB_TOKEN - Workflow syntax for GitHub Actions <title>Result 3</title> https://docs.github.com/en/pull-requests/how-tos/merge-and-close-pull-requests/automatically-merging-a-pull-request # Automatically merging a pull request Enable or disable auto-merge for pull requests to streamline your workflow and automatically merge changes once all requirements are met. ## About auto-merge Auto-merge merges a pull request automatically after all required reviews and status checks pass. Before you use auto-merge, it must be enabled for the repository. See Managing auto-merge for pull requests in your repository. Auto-merge is disabled if someone without write permissions pushes new changes to the head branch or switches the base branch. ## Enabling auto-merge > [!NOTE] > The option to enable auto-merge is shown only on pull requests that cannot be merged immediately. For example, when a branch protection rule enforces "Require pull request reviews before merging" or "Require status checks to pass before merging" and these conditions are not yet met. For more information, see Managing a branch protection rule. People with write permissions to a repository can enable auto-merge for a pull request. 1. On GitHub, navigate to the main page of the repository. 2. Under your repository name, click ** Pull requests**. 3. In the "Pull Requests" list, click the pull request you want to auto-merge. 4. Optionally, select the dropdown menu, then click a merge method. See Pull request merges. 5. Click Enable auto-merge. 6. If you chose the merge or squash and merge methods, type a commit message and description and choose the email address you want to author the merge commit. [!NOTE] The email dropdown menu is not available if you have email privacy enabled or if you only have one verified and visible email associated with your GitHub account. 7. Click Confirm auto-merge. ## Disabling auto-merge People with write permissions to a repository and pull request authors can disable auto-merge for a pull request. 1. On GitHub, navigate to the main page of the repository. 2. Under your repository name, click ** Pull requests**. 3. In the "Pull Requests" list, click the pull request for which you want to disable auto-merge. 4. In the merge box, click Disable auto-merge. <title>Managing auto-merge for pull requests in your repository</title> https://docs.github.com/en/repositories/configuring-branches-and-merges-in-your-repository/configuring-pull-request-merges/managing-auto-merge-for-pull-requests-in-your-repository # Managing auto-merge for pull requests in your repository You can allow or disallow auto-merge for pull requests in your repository. ## About auto-merge If you allow auto-merge for pull requests in your repository, people with write permissions can configure individual pull requests in the repository to merge automatically when all merge requirements are met. If someone who does not have write permissions pushes changes to a pull request that has auto-merge enabled, auto-merge will be disabled for that pull request. For more information, see Automatically merging a pull request. ## Managing auto-merge > [!NOTE] > The option to enable auto-merge is shown only on pull requests that cannot be merged immediately. For example, when a branch protection rule enforces "Require pull request reviews before merging" or "Require status checks to pass before merging" and these conditions are not yet met. For more information, see Managing a branch protection rule. 1. On GitHub, navigate to the main page of the repository. 2. Under your repository name, click ** Settings**. If you cannot see the "Settings" tab, select the **** dropdown menu, then click Settings. 3. On the left side of the page in the navigation bar, click General 4. Toward the bottom of the page under "Pull Requests", select or deselect Allow auto-merge. <title>GITHUB_TOKEN</title> https://docs.github.com/en/actions/concepts/security/github_token # GITHUB_TOKEN Learn what GITHUB_TOKEN is, how it works, and why it matters for secure automation in GitHub Actions workflows. ## About the `GITHUB_TOKEN` At the start of each workflow job, GitHub automatically creates a unique `GITHUB_TOKEN` secret to use in your workflow. You can use the `GITHUB_TOKEN` to authenticate in the workflow job. When you enable GitHub Actions, GitHub installs a GitHub App on your repository. The `GITHUB_TOKEN` secret is a GitHub App installation access token. You can use the installation access token to authenticate on behalf of the GitHub App installed on your repository. The token&`#39`;s permissions are limited to the repository that contains your workflow. For more information, see Workflow syntax for GitHub Actions. Before each job begins, GitHub fetches an installation access token for the job. The `GITHUB_TOKEN` expires when the job finishes or after its effective maximum lifetime. The effective maximum lifetime of the token depends on the type of runner: - GitHub-hosted runners The maximum job execution time is 6 hours, so the `GITHUB_TOKEN` can live for a maximum of 6 hours. - Self-hosted runners The maximum job execution time is 5 days. However, because the `GITHUB_TOKEN` is an installation access token, it can only be refreshed for up to 24 hours. If your job runs longer than 24 hours, use a personal access token or other authentication method instead. The token is also available in the `github.token` context. For more information, see Contexts reference. ## When `GITHUB_TOKEN` triggers workflow runs When you use the repository&`#39`;s `GITHUB_TOKEN` to perform tasks, events triggered by the `GITHUB_TOKEN` will not create a new workflow run, with the following exceptions: - `workflow_dispatch` and `repository_dispatch` events always create workflow runs. - `pull_request` events with the `opened`, `synchronize`, or `reopened` activity types: when a workflow using `GITHUB_TOKEN` creates or updates a pull request, the resulting `pull_request` event creates workflow runs in an approval-required state. The pull request displays a banner in the merge box, and a user with write access to the repository can start the runs by selecting Approve workflows to run. Other `pull_request` activity types (such as `labeled`, `edited`, or `closed`) do not create workflow runs. This prevents recursive workflow runs while still allowing CI workflows to run on pull requests created by automation. For more information about approving workflow runs, see Approving workflow runs from forks. For all other events, this behavior prevents you from accidentally creating recursive workflow runs. For example, if a workflow run pushes code using the repository&`#39`;s `GITHUB_TOKEN`, a new workflow will not run even when the repository contains a workflow configured to run when `push` events occur. > [!NOTE] > If you need workflow runs from workflow-created pull requests to execute without requiring approval, use a GitHub App installation access token or a personal access token instead of `GITHUB_TOKEN` when creating or updating the pull request. Commits pushed by a GitHub Actions workflow that uses the `GITHUB_TOKEN` do not trigger a GitHub Pages build. ## Next steps - Use GITHUB_TOKEN for authentication in workflows - Workflow syntax for GitHub Actions
