En esta página, se explican las diferencias entre los mensajes de texto y los de tarjeta.
Cuando las apps de Chat envían mensajes de texto para transmitir información básica, los mensajes aparecen intercalados, al igual que cuando las personas escriben mensajes en Google Chat. Para crear mensajes que contengan más que texto o mensajes con los que los usuarios puedan interactuar, las apps de Chat pueden usar tarjetas.
Las apps de chat también pueden agregar un mensaje de texto con una tarjeta. Para solicitar a los usuarios que finalicen procesos de varios pasos, como completar un formulario, las apps de Chat también pueden crear tarjetas que se abran en una ventana nueva como diálogos.
Anatomía de un mensaje de texto
En la API de Google Chat, los mensajes se representan como objetos JSON. Dentro de un mensaje, un mensaje de texto se representa como un objeto text.
En el siguiente ejemplo, una app de Chat crea un mensaje de texto en un espacio para un equipo de desarrolladores de software que se acerca a la congelación del código:
{"text":"Attention <users/all>: Code freeze starts at `11:59 am` Pacific Standard Time! If you need a little more time, type `/moreTime` and I'll push the code freeze back one hour."}
El JSON devuelve el siguiente mensaje:
Anatomía de un mensaje de tarjeta
En la API de Google Chat, los mensajes se representan como objetos JSON. Dentro de un mensaje, una tarjeta se representa como un array de cardsV2 y consta de lo siguiente:
Un cardId, que se usa para identificar la tarjeta y se limita a un mensaje determinado.
(Las tarjetas de diferentes mensajes pueden tener el mismo ID).
Un objeto card, que consta de lo siguiente:
Un objeto header que especifica elementos como un título, un subtítulo y una imagen de estilo de avatar.

To create messages that contain more than text, or to create\nmessages that users can interact with, Chat apps can use\n[cards](/workspace/chat/create-messages#create).\nChat apps can also append a text message with a card. To\nprompt users to finish multi-step processes such as completing a form,\nChat apps can also create cards that open in a new window as\n[dialogs](/workspace/chat/dialogs).\n\nAnatomy of a text message\n-------------------------\n\nIn the Google Chat API, messages are represented as JSON objects. Within a message,\na text message is represented as a\n[`text`](/workspace/chat/api/reference/rest/v1/spaces.messages#Message.FIELDS.text)\nobject.\n\nIn the following\nexample, a Chat app creates a text message in a space\nfor a team of software developers that a code freeze is approaching: \n\n {\n \"text\": \"Attention \u003cusers/all\u003e: Code freeze starts at `11:59 am` Pacific Standard Time!
