# Enable Signed Audit

Integration with 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.

{% hint style="info" %}
Enabled signed audit is optional but highly recommended to ensure data security.
{% endhint %}

## Steps

### Enable Signed Audit

1. Add the following lines of code to the birth registration persister after the `fromTopic` attribute under `mappings`:

{% code lineNumbers="true" %}

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

{% endcode %}

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.digit.org/platform/guides/developer-guide/backend-developer-guide/section-2-integrate-persister-and-kafka/enable-signed-audit.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
