# PutNotificationChannel


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.aws.amazon.com/waf/latest/developerguide/fms-security_iam_service-with-iam.html#fms-security_iam_service-with-iam-roles-service) in the * AWS Firewall Manager Developer Guide*.

## Errors


For information about the errors that are common to all actions, see [Common Error Types](CommonErrors.md).

 ** InternalErrorException **   
The operation failed because of a system problem, even though the request was valid. Retry your request.  
HTTP Status Code: 400

 ** InvalidOperationException **   
The operation failed because there was nothing to do or the operation wasn't possible. For example, you might have submitted an `AssociateAdminAccount` request for an account ID that was already set as the AWS Firewall Manager administrator. Or you might have tried to access a Region that's disabled by default, and that you need to enable for the Firewall Manager administrator account and for AWS Organizations before you can access it.  
HTTP Status Code: 400

 ** ResourceNotFoundException **   
The specified resource was not found.  
HTTP Status Code: 400
