VerifiedPermissions / Client / update_policy

update_policy#

VerifiedPermissions.Client.update_policy(**kwargs)#

Modifies a Cedar static policy in the specified policy store. You can change only certain elements of the UpdatePolicyDefinition parameter. You can directly update only static policies. To change a template-linked policy, you must update the template instead, using UpdatePolicyTemplate.

Note

  • If policy validation is enabled in the policy store, then updating a static policy causes Verified Permissions to validate the policy against the schema in the policy store. If the updated static policy doesn’t pass validation, the operation fails and the update isn’t stored.

  • When you edit a static policy, you can change only certain elements of a static policy:

    • The action referenced by the policy.

    • A condition clause, such as when and unless.

You can’t change these elements of a static policy:

  • Changing a policy from a static policy to a template-linked policy.

  • Changing the effect of a static policy from permit or forbid.

  • The principal referenced by a static policy.

  • The resource referenced by a static policy.

  • To update a template-linked policy, you must update the template instead.

Note

Verified Permissions is eventually consistent . It can take a few seconds for a new or changed element to propagate through the service and be visible in the results of other Verified Permissions operations.
