<p>Specifies a list of principals to whom you want to the resource share. This can be <code>null</code> if you want to add only resources.</p> <p>What the principals can do with the resources in the share is determined by the RAM permissions that you associate with the resource share. See <a>AssociateResourceSharePermission</a>.</p> <p>You can include the following values:</p> <ul> <li> <p>An Amazon Web Services account ID, for example: <code>123456789012</code> </p> </li> <li> <p>An <a href="https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html">Amazon Resource Name (ARN)</a> of an organization in Organizations, for example: <code>organizations::123456789012:organization/o-exampleorgid</code> </p> </li> <li> <p>An ARN of an organizational unit (OU) in Organizations, for example: <code>organizations::123456789012:ou/o-exampleorgid/ou-examplerootid-exampleouid123</code> </p> </li> <li> <p>An ARN of an IAM role, for example: <code>iam::123456789012:role/rolename</code> </p> </li> <li> <p>An ARN of an IAM user, for example: <code>iam::123456789012user/username</code> </p> </li> </ul> <note> <p>Not all resource types can be shared with IAM roles and users. For more information, see <a href="https://docs.aws.amazon.com/ram/latest/userguide/permissions.html#permissions-rbp-supported-resource-types">Sharing with IAM roles and users</a> in the <i>Resource Access Manager User Guide</i>.</p> </note>

<p>Specifies a unique, case-sensitive identifier that you provide to ensure the idempotency of the request. This lets you safely retry the request without accidentally performing the same operation a second time. Passing the same value to a later call to an operation requires that you also pass the same value for all other parameters. We recommend that you use a <a href="https://wikipedia.org/wiki/Universally_unique_identifier">UUID type of value.</a>.</p> <p>If you don't provide this value, then Amazon Web Services generates a random one for you.</p> <p>If you retry the operation with the same <code>ClientToken</code>, but with different parameters, the retry fails with an <code>IdempotentParameterMismatch</code> error.</p>

Specifies a list of <a href="https://docs.aws.amazon.com/general/latest/gr/aws-arns-and-namespaces.html">Amazon Resource Names (ARNs)</a> of the resources that you want to share. This can be <code>null</code> if you want to add only principals.
