You can create cooldown policies via the Cloudsmith API, Terraform provider, and web app.



## Getting started

This feature is available in early access for Ultra and Enterprise customers.  


Cooldown policies are now supported for npm, Python, Go, and NuGet. For more information about using cooldown policies, see [our documentation](https://docs.cloudsmith.com/supply-chain-security/epm/cooldown-policy).
