Chat 앱에서 기본 정보를 전달하기 위해 문자 메시지를 보내면 Google Chat 사용자가 메시지를 작성하는 방식과 마찬가지로 메시지가 인라인으로 표시됩니다. 텍스트 이상의 콘텐츠가 포함된 메시지를 만들거나 사용자가 상호작용할 수 있는 메시지를 만들려면 Chat 앱에서 카드를 사용할 수 있습니다.
채팅 앱은 카드와 함께 문자 메시지를 추가할 수도 있습니다. 사용자에게 양식 작성과 같은 다단계 프로세스를 완료하라는 메시지를 표시하기 위해 Chat 앱은 새 창에서 대화상자로 열리는 카드를 만들 수도 있습니다.
문자 메시지의 구조
Google Chat API에서 메시지는 JSON 객체로 표현됩니다. 메시지 내에서 텍스트 메시지는 text 객체로 표현됩니다.
다음 예에서 채팅 앱은 코드 동결이 다가오는 소프트웨어 개발자 팀의 스페이스에 텍스트 메시지를 만듭니다.
{"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."}
JSON은 다음 메시지를 반환합니다.
카드 메시지의 구조
Google Chat API에서 메시지는 JSON 객체로 표현됩니다. 메시지 내에서 카드는 cardsV2 배열로 표시되며 다음으로 구성됩니다.

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!
