You can test out any action for up to 500 records using Clay's shared API key. If you have your own API key, you can easily add it in when you set up your action for the first time.

Any API key you save as public will be shared at the workspace level. Any you don't save as public will remain only available to you.

To share an API key with your team or avoid having to reenter your key across workspaces, check the box marked Make the auth account public.
