# Enable Signed Audit

## Overview

Enabling signed audit for a module ensures that all transactions - creates, updates, deletes - are recorded in a digitally signed fashion. Learn more about the signed [audit service](/platform/platform/core-services/audit-service.md) here.

## Steps

### Enable Signed Audit

{% code lineNumbers="true" %}

```yaml
isTransaction: true
isAuditEnabled: true
module: BTR
objecIdJsonPath: $.id
tenantIdJsonPath: $.tenantId
transactionCodeJsonPath: $.applicationNumber
auditAttributeBasePath: $.BirthRegistrationApplications
```

{% endcode %}
