# Migración

Por favor, consulte pos-getting-started para una descripción y ejemplos del proceso de inicialización en 3.x, por ejemplo, usar “Payment.create()” frente a “new Payment” para crear objetos, e importar “com.verifone.payment\_sdk.Payment” frente a “com.verifone.commerce.entities.Payment”.

Nota

* En los terminales CM5 y Trinity, configure Device Manager > Transaction Options > Terminal.1 > UseDeveloperSDK en “0” para usar el SDK 3.x.

## Cambios en la API <a href="#api-changes" id="api-changes"></a>

* El ID de sesión de estado se ha movido a Commerce Event.
* TransactionManager.getTransactionManager se ha movido a PaymentSdk.getTransactionManager().
* [TransactionManager.TearDown()](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md) se ha eliminado y ya no es accesible como una API de TransactionManager.

## Migración de CommerceListener y PsdkStatusListener a CommerceListenerAdapter <a href="#migration-from-commercelistener-and-psdkstatuslistener-to-commercelisteneradapter" id="migration-from-commercelistener-and-psdkstatuslistener-to-commercelisteneradapter"></a>

* [CommerceListener](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_commerce_listener2_8java.md) y [PsdkStatusListener](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_psdk_status_listener_8java.md) se están deprecando y consolidando en un solo listener [CommerceListenerAdapter](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_commerce_listener_adapter_8java.md). Los listeners antiguos y nuevos y las respectivas APIs no deben usarse en conjunto.

Para usar el nuevo CommerceListener:

* crear [CommerceListenerAdapter](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_commerce_listener_adapter_8java.md)
* Use la API [PaymentSdk.initializeFromValues(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_8java.md) con este listener.
* Obtenga el [TransactionManager](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md) usando [PaymentSdk.getTransactionManager(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_8java.md)
* Para iniciar sesión en el terminal, cree las credenciales de inicio de sesión y llame a [TransactionManager.loginWithCredentials()](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md)
* Para iniciar una sesión, llame a [TransactionManager.startSession2(…)<br>](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md)

* inicio de sesión-cierre de sesión.
* inicio de sesión.

Nota

* Asegúrese de usar CommerceListenerAdapter solo con las nuevas APIs. Usar APIs obsoletas junto con CommerceListenerAdapter o viceversa podría provocar un comportamiento inesperado.

## Cambios en la API <a href="#id1" id="id1"></a>

* [PaymentSdk.initialize(PsdkStatusListener)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md) API se reemplaza con [PaymentSdk.initialize(…)<br>](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md)
* [PaymentSdk.initializeFromValues(PsdkStatusListener,HashMap)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md) API se reemplaza con [PaymentSdk.initializeFromValues(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md)
* [PaymentSdk.initializeFromFile(PsdkStatusListener,String)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md) API se reemplaza con [PaymentSdk.initializeFromFile(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md)
* [PaymentSdk.displayConfiguration(PsdkStatusListener)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md) API se reemplaza con [PaymentSdk.displayConfiguration(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_payment_sdk_base_8java.md)
* [TransactionManager.startSession(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md) se ha movido a [TransactionManager.startSession2(…)<br>](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md)
* [TransactionManager.Login(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md) se ha movido a [TransactionManager.loginWithCredentials(…)](https://github.com/iKettles/verifone-migration-test/blob/main/psdk/_generated/java/file/_transaction_manager_8java.md)

# Agent Instructions
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://docs.verifone.com/psdk/psdk-es/no-estas-seguro-de-donde-estan-ubicados/migration.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.
