How Amazon Chime works with IAM - Amazon Chime

How Amazon Chime works with IAM

Before you use IAM to manage access to Amazon Chime, you should understand what IAM features are available to use with Amazon Chime. To get a high-level view of how Amazon Chime and other AWS services work with IAM, see AWS services that work with IAM in the IAM User Guide.

Amazon Chime identity-based policies

With IAM identity-based policies, you can specify allowed or denied actions and resources as well as the conditions under which actions are allowed or denied. Amazon Chime supports specific actions, resources, and condition keys. To learn about all of the elements that you use in a JSON policy, see IAM JSON policy elements reference in the IAM User Guide.


Administrators can use AWS JSON policies to specify who has access to what. That is, which principal can perform actions on what resources, and under what conditions.

The Action element of a JSON policy describes the actions that you can use to allow or deny access in a policy. Policy actions usually have the same name as the associated AWS API operation. There are some exceptions, such as permission-only actions that don't have a matching API operation. There are also some operations that require multiple actions in a policy. These additional actions are called dependent actions.

Include actions in a policy to grant permissions to perform the associated operation.

Policy actions in Amazon Chime use the following prefix before the action: chime:. For example, to grant someone permission to access a list of Amazon Chime users in your account with the Amazon Chime ListUsers API operation, you include the chime:ListUsers action in their policy. Policy statements must include either an Action or NotAction element. Amazon Chime 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": [ "chime:ListUsers", "chime:InviteUsers"

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

"Action": "chime:Get*"

To see a list of Amazon Chime actions, see Actions defined by Amazon Chime in the IAM User Guide.


Amazon Chime does not support specifying resource ARNs in a policy.

Condition keys

Amazon Chime does not provide any service-specific condition keys. To see all AWS global condition keys, see AWS Global Condition Context Keys in the IAM User Guide.

Amazon Chime resource-based policies

Amazon Chime does not support resource-based policies.

Authorization based on Amazon Chime tags

Amazon Chime does not support tagging resources or controlling access based on tags.

Amazon Chime IAM roles

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

Using temporary credentials with Amazon Chime

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.

Amazon Chime supports using temporary credentials.

Service-linked roles

Service-linked roles allow AWS services to access resources in other services to complete an action on your behalf. Service-linked roles appear in your IAM account and are owned by the service. An IAM administrator can view but not edit the permissions for service-linked roles.

Amazon Chime supports service-linked roles. For details about creating or managing Amazon Chime service-linked roles, see Using service-linked roles for Amazon Chime.

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.

Amazon Chime does not support service roles.
