Disabling a workflow allows you to stop a workflow from being triggered without having to delete the file from the repo. You can easily re-enable the workflow again on GitHub.
Temporarily disabling a workflow can be useful in many scenarios. These are a few examples where disabling a workflow might be helpful:
- A workflow error that produces too many or wrong requests, impacting external services negatively.
- A workflow that is not critical and is consuming too many minutes on your account.
- A workflow that sends requests to a service that is down.
- Workflows on a forked repository that aren't needed (for example, scheduled workflows).
Warning: To prevent unnecessary workflow runs, scheduled workflows may be disabled automatically. When a public repository is forked, scheduled workflows are disabled by default. In a public repository, scheduled workflows are automatically disabled when no repository activity has occurred in 60 days.
Disabling and enabling workflows with the GitHub UI
Disabling a workflow
You can manually disable a workflow so that it won't execute any workflow runs. A disabled workflow is not deleted, and can be re-enabled.
- Navigiere in GitHub zur Hauptseite des Repository.
- Klicke unter Deinem Repository-Namen auf Actions (Aktionen).
- In the left sidebar, click the workflow you want to disable.
- Click .
- Click Disable workflow.
The disabled workflow is marked to indicate its status. 
Enabling a workflow
You can re-enable a workflow that was previously disabled.
- Navigiere in GitHub zur Hauptseite des Repository.
- Klicke unter Deinem Repository-Namen auf Actions (Aktionen).
- In the left sidebar, click the workflow you want to enable.
- Click Enable workflow.
Disabling and enabling workflows with GitHub CLI
For information on setting up GitHub CLI, see "Managing GitHub Actions with GitHub CLI."
To disable a workflow, use the workflow disable subcommand. Replace workflow with either the name, ID, or file name of the workflow you want to disable. For example, "Link Checker", 1234567, or "link-check-test.yml". If you don't specify a workflow, GitHub CLI returns an interactive menu for you to choose a workflow.

For example, "Link Checker", 1234567, or "link-check-test.yml". If you don't specify a workflow, GitHub CLI returns an interactive menu for you to choose a workflow.

You can also disable and enable a workflow using the REST API. For more information, see the "Actions REST API."
