# 4 Key Digital Functionalities

The Messaging Building Block is a standalone messaging gateway/client/proxy (including all possible modalities: email, SMS, etc.) but can also facilitate connections with existing messaging service providers by enabling safe communication. The communication in this Building Block can be categorized in two different directions as follows:

## 4.1 Government to person (G2P) <a href="#docs-internal-guid-c38a9447-7fff-fcb5-e6eb-c6419072f004" id="docs-internal-guid-c38a9447-7fff-fcb5-e6eb-c6419072f004"></a>

> In scope of v1

* informing End clients about their registration;
* reminding and requesting End clients' confirmation for appointment booking or other events;
* getting confirmation about government services and interactions.

> In scope of future releases

* delivering information at scale to End clients;
* alerting End clients in emergency contexts.

## 4.2 Person to Government (P2G) <a href="#docs-internal-guid-c38a9447-7fff-fcb5-e6eb-c6419072f004" id="docs-internal-guid-c38a9447-7fff-fcb5-e6eb-c6419072f004"></a>

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

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://specs.govstack.global/messaging/4-key-digital-functionalities.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

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.
