# Background Tasks { #background-tasks }

You can define background tasks to be run *after* returning a response.

This is useful for operations that need to happen after a request, but that the client doesn't really have to be waiting for the operation to complete before receiving the response.

This includes, for example:

* Email notifications sent after performing an action:

import java.io.IOException;

import jcifs.CIFSException;
import jcifs.SmbFileHandle;
import jcifs.SmbPipeHandle;

/**
 * Internal interface for SMB pipe handle operations.
 *
 * This interface extends SmbPipeHandle with additional methods needed
 * for internal pipe management and provides access to low-level pipe details.

Si vas a la **UI de la documentación de la API** en `/docs` podrás ver la **documentación** de las cookies para tus *path operations*.

Pero incluso si **rellenas los datos** y haces clic en "Execute", como la UI de la documentación funciona con **JavaScript**, las cookies no serán enviadas y verás un **mensaje de error** como si no hubieras escrito ningún valor.

## Resumen { #recap }

Puedes añadir múltiples parámetros de cuerpo a tu *path operation function*, aunque un request solo puede tener un único cuerpo.

Pero **FastAPI** lo manejará, te dará los datos correctos en tu función, y validará y documentará el esquema correcto en la *path operation*.

También puedes declarar valores singulares para ser recibidos como parte del cuerpo.

    public Map<String, Object> process(final Map<String, Object> target, final AccessResult<String> accessResult) {
        return process(target);
    }

    /**
     * Processes a document map for datastore operations.
     * Default implementation delegates to the basic process method.
     *
     * @param target the document data to process
     * @param params the data store parameters
     * @return the processed document data
