When a metadata template has been applied to a folder, a metadata cascade policy
can be created by calling the  <Link href="/reference/post-metadata-cascade-policies">`POST /metadata_cascade_policies`</Link> API
endpoint with the `folder_id` of the folder to apply the policy to, and the
`scope` and `templateKey` of metadata template to.

<Info>
  To get the `scope` and `templateKey` for a template, either
  <Link href="/guides/metadata/templates/list">list all metadata templates</Link>, or
  <Link href="/guides/metadata/instances/list">list all instances on an file</Link>.
</Info>

<Warning>
  A cascade policy can only be created if a metadata instance has already been
  applied to the folder with the given `scope` and `templateKey`.
