# Transaction Rules Overview

> Transaction Rules allow users to automatically recategorize or rename all similar transactions according to their preferences.

<Note>
  For field names, types, and descriptions, see the response schema on each endpoint page, such as [Read Transaction Rule](/api-reference/platform-api/v20260929/reference/transaction-rules/read-transaction-rule) and [List Transaction Rules](/api-reference/platform-api/v20260929/reference/transaction-rules/list-transaction-rules).
</Note>

When recategorizing or renaming a transaction, the user will be asked whether they want the new data to apply to the selected transaction or to all future transactions. If they choose to apply it to all future transactions, it will create a transaction rule which will automatically apply the changes going forward.
