 # Create GitHub App Token

+
 GitHub Action for creating a GitHub App installation access token.
 
 ## Usage
 
 In order to use this action, you need to:
 
-1. [Register new GitHub App](https://docs.github.com/apps/creating-github-apps/setting-up-a-github-app/creating-a-github-app)
-2. [Store the App's ID in your repository environment variables](https://docs.github.com/actions/learn-github-actions/variables#defining-configuration-variables-for-multiple-workflows) (example: `APP_ID`)
-3. [Store the App's private key in your repository secrets](https://docs.github.com/actions/security-guides/encrypted-secrets?tool=webui#creating-encrypted-secrets-for-a-repository) (example: `PRIVATE_KEY`)
+1. [Register new GitHub App](https://docs.github.com/apps/creating-github-apps/setting-up-a-github-app/creating-a-github-app).
+2. [Store the App's ID or Client ID in your repository environment variables](https://docs.github.com/actions/learn-github-actions/variables#defining-configuration-variables-for-multiple-workflows) (example: `APP_ID`).
+3. [Store the App's private key in your repository secrets](https://docs.github.com/actions/security-guides/encrypted-secrets?tool=webui#creating-encrypted-secrets-for-a-repository) (example: `PRIVATE_KEY`).
 
-### Minimal usage
+> [!IMPORTANT]  
+> An installation access token expires after 1 hour. Please [see this comment](https://github.com/actions/create-github-app-token/issues/121#issuecomment-2043214796) for alternative approaches if you have long-running processes.

+>
+> For example, we can check at `https://api.github.com/users/dependabot[bot]` to see the user ID of Dependabot is 49699333.

 ## Inputs
 
-### `app_id`
+### `app-id`
 
 **Required:** GitHub App ID.
 
-### `private_key`
+### `private-key`
 
-**Required:** GitHub App private key.
+**Required:** GitHub App private key. Escaped newlines (`\\n`) will be automatically replaced with actual newlines.
+
+Some other actions may require the private key to be Base64 encoded. To avoid recreating a new secret, it can be decoded on the fly, but it needs to be managed securely. Here is an example of how this can be achieved:
+
+```yaml
+steps:
+  - name: Decode the GitHub App Private Key
+    id: decode
+    run: |
+      private_key=$(echo "${{ secrets.PRIVATE_KEY }}" | base64 -d | awk 'BEGIN {ORS="\\n"} {print}' | head -c -2) &> /dev/null
+      echo "::add-mask::$private_key"
+      echo "private-key=$private_key" >> "$GITHUB_OUTPUT"
+  - name: Generate GitHub App Token
+    id: app-token
+    uses: actions/create-github-app-token@v2
+    with:
+      app-id: ${{ vars.APP_ID }}
+      private-key: ${{ steps.decode.outputs.private-key }}
+```
+
+### `owner`
+
+**Optional:** The owner of the GitHub App installation. If empty, defaults to the current repository owner.
+
+### `repositories`
+
+**Optional:** Comma or newline-separated list of repositories to grant access to.
+
+> [!NOTE]
+> If `owner` is set and `repositories` is empty, access will be scoped to all repositories in the provided repository owner's installation. If `owner` and `repositories` are empty, access will be scoped to only the current repository.
+
+### `permission-<permission name>`
+
+**Optional:** The permissions to grant to the token. By default, the token inherits all of the installation's permissions. We recommend to explicitly list the permissions that are required for a use case. This follows GitHub's own recommendation to [control permissions of `GITHUB_TOKEN` in workflows](https://docs.github.com/en/actions/writing-workflows/choosing-what-your-workflow-does/controlling-permissions-for-github_token). The documentation also lists all available permissions, just prefix the permission key with `permission-` (e.g., `pull-requests` → `permission-pull-requests`).
+
+The reason we define one `permision-<permission name>` input per permission is to benefit from type intelligence and input validation built into GitHub's action runner.
+
+### `skip-token-revoke`
+
+**Optional:** If true, the token will not be revoked when the current job is complete.
+
+### `github-api-url`
+
+**Optional:** The URL of the GitHub REST API. Defaults to the URL of the GitHub Rest API where the workflow is run from.

 ## How it works
 
 The action creates an installation access token using [the `POST /app/installations/{installation_id}/access_tokens` endpoint](https://docs.github.com/rest/apps/apps?apiVersion=2022-11-28#create-an-installation-access-token-for-an-app). By default,
 
-1. The token is scoped to the current repository.
+1. The token is scoped to the current repository or `repositories` if set.
 2. The token inherits all the installation's permissions.
 3. The token is set as output `token` which can be used in subsequent steps.
-4. The token is revoked in the `post` step of the action, which means it cannot be passed to another job.
+4. Unless the `skip-token-revoke` input is set to true, the token is revoked in the `post` step of the action, which means it cannot be passed to another job.
 5. The token is masked, it cannot be logged accidentally.
 
 > [!NOTE]
 > Installation permissions can differ from the app's permissions they belong to. Installation permissions are set when an app is installed on an account. When the app adds more permissions after the installation, an account administrator will have to approve the new permissions before they are set on the installation.

+# Tests
+
+Add one test file per scenario. You can run them in isolation with:
+
+```bash
+node tests/post-token-set.test.js
+```
+
+All tests are run together in [tests/index.js](index.js), which can be executed with ava
+
+```
+npx ava tests/index.js
+```
+
+or with npm
+
+```
+npm test
+```
+
+## How the tests work
+
+The output from the tests is captured into a snapshot ([tests/snapshots/index.js.md](snapshots/index.js.md)). It includes all requests sent by our scripts to verify it's working correctly and to prevent regressions.
+
+## How to add a new test
+
+We have tests both for the `main.js` and `post.js` scripts.
+
+- If you do not expect an error, take [main-token-permissions-set.test.js](tests/main-token-permissions-set.test.js) as a starting point.
+- If your test has an expected error, take [main-missing-app-id.test.js](tests/main-missing-app-id.test.js) as a starting point.
