How Alexa for Business Works with IAM

Before you use IAM to manage access to Alexa for Business, you should understand what IAM features are available to use with Alexa for Business. To get a high-level view of how Alexa for Business and other AWS services work with IAM, see AWS Services That Work with IAM in the IAM User Guide.

Alexa for Business Identity-Based Policies

With IAM identity-based policies, you can specify allowed or denied actions and resources, and also the conditions under which actions are allowed or denied. Alexa for Business supports specific actions, resources, and condition keys. For more information about all of the elements that you use in a JSON policy, see IAM JSON Policy Elements Reference in the IAM User Guide.


The Action element of an IAM identity-based policy describes the specific action or actions that will be allowed or denied by the policy. Policy actions usually have the same name as the associated AWS API operation. The action is used in a policy to grant permissions to perform the associated operation.

Policy actions in Alexa for Business use the following prefix before the action: a4b:. For example, to grant someone permission to run an Amazon EC2 instance with the Amazon EC2 RunInstances API operation, you include the ec2:RunInstances action in their policy. Policy statements must include either an Action or NotAction element. Alexa for Business defines its own set of actions that describe tasks that you can perform with this service.

To specify multiple actions in a single statement, separate them with commas as follows:

"Action": [ "ec2:action1", "ec2:action2"

You can specify multiple actions using wildcards (*). For example, to specify all actions that begin with the word Describe, include the following action:

"Action": "ec2:Describe*"

To see a list of Alexa for Business actions, see Actions Defined by Alexa for Business in the IAM User Guide.


The Resource element specifies the object or objects to which the action applies. Statements must include either a Resource or a NotResource element. You specify a resource using an ARN or using the wildcard (*) to indicate that the statement applies to all resources.

The Amazon EC2 instance resource has the following ARN:


For more information about the format of ARNs, see Amazon Resource Names (ARNs) and AWS Service Namespaces.

For example, to specify the i-1234567890abcdef0 instance in your statement, use the following ARN:

"Resource": "arn:aws:ec2:us-east-1:123456789012:instance/i-1234567890abcdef0"

To specify all instances that belong to a specific account, use the wildcard (*):

"Resource": "arn:aws:ec2:us-east-1:123456789012:instance/*"

Some Alexa for Business actions, such as those for creating resources, cannot be performed on a specific resource. In those cases, you must use the wildcard (*).

"Resource": "*"

Many Amazon EC2 API actions involve multiple resources. For example, AttachVolume attaches an Amazon EBS volume to an instance, so an IAM user must have permissions to use the volume and the instance. To specify multiple resources in a single statement, separate the ARNs with commas.

"Resource": [ "resource1", "resource2"

To see a list of Alexa for Business resource types and their ARNs, see Resources Defined by Alexa for Business in the IAM User Guide. To learn with which actions you can specify the ARN of each resource, see Actions Defined by Alexa for Business.

Alexa for Business IAM Roles

An IAM role is an entity within your AWS account that has specific permissions.

Using Temporary Credentials with Alexa for Business

You can use temporary credentials to sign in with federation, assume an IAM role, or to assume a cross-account role. You obtain temporary security credentials by calling AWS STS API operations such as AssumeRole or GetFederationToken.

Alexa for Business supports using temporary credentials.

Service-Linked Roles

Alexa for Business does not support service-linked roles.

Service Roles

This feature allows a service to assume a service role on your behalf. This role allows the service to access resources in other services to complete an action on your behalf. Service roles appear in your IAM account and are owned by the account. This means that an IAM administrator can change the permissions for this role. However, doing so might break the functionality of the service.

Alexa for Business supports service roles.
