# PutNotificationChannel
<a name="API_PutNotificationChannel"></a>

Designates the IAM role and Amazon Simple Notification Service (SNS) topic that Firewall Manager uses to record SNS logs.

To perform this action outside of the console, you must first configure the SNS topic's access policy to allow the `SnsRoleName` to publish SNS logs. If the `SnsRoleName` provided is a role other than the `AWSServiceRoleForFMS` service-linked role, this role must have a trust relationship configured to allow the Firewall Manager service principal `fms.amazonaws.com` to assume this role. For information about configuring an SNS access policy, see [Service roles for Firewall Manager](https://docs.amazonaws.cn/waf/latest/developerguide/fms-security_iam_service-with-iam.html#fms-security_iam_service-with-iam-roles-service) in the * Amazon Firewall Manager Developer Guide*.
