# MX

> Import bank account activity aggregated through MX into your customers' books.

If your platform uses [MX](https://www.mx.com/) for bank connectivity, Layer can ingest the account data you already aggregate. Transactions and balances from your customers' MX-connected accounts flow into their books, so customers don't need to link their banks a second time.

## Setup

Grant Layer access to your MX data and map each customer's connected accounts to their Layer business. Your Layer contact will help you establish the connection.

Layer ingests transactions and balances as new activity comes in. Imported accounts behave like any other account in Layer, flowing through [transaction categorization](/guides/transaction-categorization) and [reporting](/guides/reporting).

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

<Note>
  Don't have an existing aggregator relationship? Layer's [Plaid integration](/integrations/banking/plaid) includes a fully managed connection, with prebuilt account linking UI.
</Note>

## Importing directly instead

To push aggregated account activity to Layer yourself, create a [Custom Account](/api-reference/v1/create-custom-account) for each account and pass its activity to the [Import Transactions](/api-reference/v1/import-transactions) endpoint. The [bank data guide](/guides/importing-bank-data) covers this in full.
