# Amazon S3

> Export your customers' accounting data from Layer to an Amazon S3 bucket.

Layer can deliver your platform's accounting data as files to an [Amazon S3](https://aws.amazon.com/s3/) bucket you control. Unlike Layer's other integrations, this one flows outward: bank transactions, ledger activity, and report outputs from Layer arrive in your bucket on a schedule, ready to load into whatever stack sits downstream.

## Setup

Work with your Layer contact to choose the datasets you need, the delivery schedule, and the destination bucket and prefix. Once configured, Layer keeps the exported files current, and each customer's records carry their business ID so you can join them to your own data.

Typical uses include feeding a data lake, archiving accounting records, and staging data for downstream ETL into your warehouse of choice.

This integration is enabled per platform. Reach out to your Layer contact to turn it on.

## Pulling data via API instead

For one-off or lighter-weight needs, the API exposes the same data directly: list endpoints such as [List Bank Transactions](/api-reference/v1/list-bank-transactions) and [List Ledger Entries](/api-reference/v1/list-ledger-entries), and export endpoints such as [Export Ledger Entries as CSV](/api-reference/v1/export-ledger-entries-csv).
