list_policies_granting_service_access#

IAM.Client.list_policies_granting_service_access(**kwargs)#

Retrieves a list of policies that the IAM identity (user, group, or role) can use to access each specified service.

Note

This operation does not use other policy types when determining whether a resource could access a service. These other policy types include resource-based policies, access control lists, Organizations policies, IAM permissions boundaries, and STS assume role policies. It only applies permissions policy logic. For more about the evaluation of policy types, see Evaluating policies in the IAM User Guide.

The list of policies returned by the operation depends on the ARN of the identity that you provide.

  • User – The list of policies includes the managed and inline policies that are attached to the user directly. The list also includes any additional managed and inline policies that are attached to the group to which the user belongs.

  • Group – The list of policies includes only the managed and inline policies that are attached to the group directly. Policies that are attached to the group’s user are not included.

  • Role – The list of policies includes only the managed and inline policies that are attached to the role.

For each managed policy, this operation returns the ARN and policy name. For each inline policy, it returns the policy name and the entity to which it is attached. Inline policies do not have an ARN. For more information about these policy types, see Managed policies and inline policies in the IAM User Guide.

Policies that are attached to users and roles as permissions boundaries are not returned. To view which managed policy is currently used to set the permissions boundary for a user or role, use the GetUser or GetRole operations.

Request Syntax

response = client.list_policies_granting_service_access(
    Marker='string',
    Arn='string',
    ServiceNamespaces=[
        'string',
    ]
)
Parameters:
  • Marker (string) – Use this parameter only when paginating results and only after you receive a response indicating that the results are truncated. Set it to the value of the Marker element in the response that you received to indicate where the next call should start.

  • Arn (string) –

    [REQUIRED]

    The ARN of the IAM identity (user, group, or role) whose policies you want to list.

  • ServiceNamespaces (list) –

    [REQUIRED]

    The service namespace for the Amazon Web Services services whose policies you want to list.

    To learn the service namespace for a service, see Actions, resources, and condition keys for Amazon Web Services services in the IAM User Guide. Choose the name of the service to view details for that service. In the first paragraph, find the service prefix. For example, (service prefix: a4b). For more information about service namespaces, see Amazon Web Services service namespaces in the Amazon Web Services General Reference.

    • (string) –

Response Structure

  • (dict) –

    • PoliciesGrantingServiceAccess (list) –

      ListPoliciesGrantingServiceAccess object that contains details about the permissions policies attached to the specified identity (user, group, or role).

      • (dict) –

        Contains details about the permissions policies that are attached to the specified identity (user, group, or role).

        This data type is used as a response element in the ListPoliciesGrantingServiceAccess operation.

        • ServiceNamespace (string) –

          The namespace of the service that was accessed.

          To learn the service namespace of a service, see Actions, resources, and condition keys for Amazon Web Services services in the Service Authorization Reference. Choose the name of the service to view details for that service. In the first paragraph, find the service prefix. For example, (service prefix: a4b). For more information about service namespaces, see Amazon Web Services service namespaces in the Amazon Web Services General Reference.

        • Policies (list) –

          The  PoliciesGrantingServiceAccess object that contains details about the policy.

          • (dict) –

            Contains details about the permissions policies that are attached to the specified identity (user, group, or role).

            This data type is an element of the ListPoliciesGrantingServiceAccessEntry object.

            • PolicyName (string) –

              The policy name.

            • PolicyType (string) –

              The policy type. For more information about these policy types, see Managed policies and inline policies in the IAM User Guide.

            • PolicyArn (string) –

              The Amazon Resource Name (ARN). ARNs are unique identifiers for Amazon Web Services resources.

              For more information about ARNs, go to Amazon Resource Names (ARNs) in the Amazon Web Services General Reference.

            • EntityType (string) –

              The type of entity (user or role) that used the policy to access the service to which the inline policy is attached.

              This field is null for managed policies. For more information about these policy types, see Managed policies and inline policies in the IAM User Guide.

            • EntityName (string) –

              The name of the entity (user or role) to which the inline policy is attached.

              This field is null for managed policies. For more information about these policy types, see Managed policies and inline policies in the IAM User Guide.

    • IsTruncated (boolean) –

      A flag that indicates whether there are more items to return. If your results were truncated, you can make a subsequent pagination request using the Marker request parameter to retrieve more items. We recommend that you check IsTruncated after every call to ensure that you receive all your results.

    • Marker (string) –

      When IsTruncated is true, this element is present and contains the value to use for the Marker parameter in a subsequent pagination request.

Exceptions

  • IAM.Client.exceptions.NoSuchEntityException

  • IAM.Client.exceptions.InvalidInputException
