You can use a matrix strategy to create tokens for multiple user or organization accounts.
Note
See this documentation for information on using multiline strings in workflows.

Required: GitHub App ID.
Required: GitHub App private key.
Optional: GitHub App installation owner. If empty, defaults to the current repository owner.
Optional: Comma-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.
Optional: If truthy, the token will not be revoked when the current job is complete.
Optional: The URL of the GitHub REST API. Defaults to the URL of the GitHub Rest API where the workflow is run from.
GitHub App installation access token.
The action creates an installation access token using the POST /app/installations/{installation_id}/access_tokens
endpoint. By default,
- The token is scoped to the current repository or
repositories
if set. - The token inherits all the installation's permissions.
- The token is set as output
token
which can be used in subsequent steps. - Unless the
skip-token-revoke
input is set to a truthy value, the token is revoked in thepost
step of the action, which means it cannot be passed to another job. - 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.
