# Versão 1.0.30

### Por que uma nova Versão?

A versão **1.0.30** inclui a funcionalidade de impedir que uma transação seja iniciada nas seguintes condições:

* quando o valor for **R$ 0,00**;
* quando houver **parcelas inválidas** (por exemplo, débito com parcela maior que 1).

### Quais são as Principais Mudanças? 

Foi incluído um novo **`viewData`** (**PaymentInformationInvalidViewData**), que é retornado pelo SDK ao cliente que o consome (TTP), sempre que for identificada alguma **inconsistência nas informações relacionadas à transação**.

A forma de como implementar essa feature se encontra na seção "9-Reagindo a Transações inválidas"

This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively. Learn more at gitbook.com.

## 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://ftcoders.first-tech.com/first-tech-ttp-sdk-pt/notas-de-versao/versao-1.0.30.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.
