# Configuring an Amazon SNS Notification Publisher instance

Create and configure an Amazon SNS notification publisher instance to help subscribers effectively direct their messages to their intended audiences.

## About this task

When using an Amazon SNS notification publisher, PingFederate is the publisher, and the intended recipients are the subscribers. Topics are the destinations to which PingFederate publishes messages. When configuring an Amazon SNS notification publisher instance, you must specify an Amazon SNS topic.

For more information about Amazon SNS and topic management, see the AWS documentation on [What is Amazon SNS?](https://docs.aws.amazon.com/sns/latest/dg/welcome.html).

## Steps

1. On the **Instance Configuration** tab, configure the notification publisher instance as follows.

   | Field                | Description                                                                                                                                                                              |
   | -------------------- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------- |
   | **SNS Topic ARN**    | The Amazon Resource Name (ARN) topic to which PingFederate publishes messages. Enter an ARN in the following format.`arn:aws:[service]:[region]:[accountid]:[resourceType/resourcePath]` |
   | **Max Payload Size** | The maximum payload size in kilobytes. Enter a value between 1 and 8192.Click **Show Advanced Fields** to reveal this field. The default value is `256`.                                 |

2. Click **Next** to view the **Summary** tab, and then click **Save**.

## Result

PingFederate categorizes notification messages into various event types. Each event type comes with a set of relevant information to help subscribers craft the final message for the intended audience.
