The S3 Notifier output connection will send submission data and state-change notifications to the Amazon S3 URI you specify. Each file’s name will be in the format _____.json_.

If you would like to use the S3 Notifier connection in a SaaS instance and your service is not public, you should create a firewall pinhole for the connection. Contact your Hyperscience representative for more information.

## Sample use cases

- Send extracted information and submission metadata to an S3 bucket for downstream processing.
- Configure monitoring of the output bucket and alert other systems to take action on submissions, if needed.

To set up the S3 Notifier, enter the settings as described in the [Block settings table](https://help.hyperscience.ai/general-information/docs/v39-s3-notifier#block-settings-table) above.

Before deploying a flow with the S3 Notifier enabled, ensure that the credentials you’ve specified in the block settings have the _PutObject_ permission for the specified prefix.
