is_authorized_with_token

VerifiedPermissions.Client.is_authorized_with_token(**kwargs)

Makes an authorization decision about a service request described in the parameters. The principal in this request comes from an external identity source in the form of an identity token formatted as a JSON web token (JWT). The information in the parameters can also define additional context that Verified Permissions can include in the evaluation. The request is evaluated against all matching policies in the specified policy store. The result of the decision is either Allow or Deny, along with a list of the policies that resulted in the decision.

Warning

If you specify the identityToken parameter, then this operation derives the principal from that token. You must not also include that principal in the entities parameter or the operation fails and reports a conflict between the two entity sources.

If you provide only an accessToken, then you can include the entity as part of the entities parameter to provide additional attributes.

At this time, Verified Permissions accepts tokens from only Amazon Cognito.

Verified Permissions validates each token that is specified in a request by checking its expiration date and its signature.

Warning

If you delete a Amazon Cognito user pool or user, tokens from that deleted pool or that deleted user continue to be usable until they expire.

Response Structure

• (dict) –

  • decision (string) –

    An authorization decision that indicates if the authorization request should be allowed or denied.

  • determiningPolicies (list) –

    The list of determining policies used to make the authorization decision. For example, if there are multiple matching policies, where at least one is a forbid policy, then because forbid always overrides permit the forbid policies are the determining policies. If all matching policies are permit policies, then those policies are the determining policies. When no policies match and the response is the default DENY, there are no determining policies.

    • (dict) –

      Contains information about one of the policies that determined an authorization decision.

      This data type is used as an element in a response parameter for the IsAuthorized and IsAuthorizedWithToken operations.

      Example: "determiningPolicies":[{"policyId":"SPEXAMPLEabcdefg111111"}]

      • policyId (string) –

        The Id of a policy that determined to an authorization decision.

        Example: "policyId":"SPEXAMPLEabcdefg111111"

  • errors (list) –

    Errors that occurred while making an authorization decision. For example, a policy references an entity or entity attribute that does not exist in the slice.

    • (dict) –

      Contains a description of an evaluation error.

      This data type is used as a request parameter in the IsAuthorized and IsAuthorizedWithToken operations.

      • errorDescription (string) –

        The error description.
