# 빠른 시작

> 이 가이드는 Direct Message 전송과 그룹 대화 생성을 안내합니다. 관리 기능을 다루는 X API v2 standard 등급 레퍼런스입니다.

export const Button = ({href, children}) => {
  return <div className="not-prose">
    <a href={href}>
      <button className="x-btn">
        <span>{children}</span>
        <svg width="3" height="24" viewBox="0 -9 3 24" class="h-6 rotate-0 overflow-visible"><path d="M0 0L3 3L0 6" fill="none" stroke="currentColor" stroke-width="1.5" stroke-linecap="round"></path></svg>
      </button>
    </a>
  </div>;
};

이 가이드는 Direct Message 전송과 그룹 대화 생성을 안내합니다.

<Note>
  **사전 요구 사항**

  시작하기 전에 다음이 필요합니다:

  * 승인된 App이 있는 [developer account](https://developer.x.com/en/portal/petition/essential/basic-info)
  * 사용자 Access Token (`dm.write` 및 `dm.read` scope가 포함된 OAuth 2.0 PKCE)
</Note>

## 1:1 메시지 전송

<Steps>
  <Step title="수신자의 user ID 확인">
    메시지를 보낼 사용자의 user ID가 필요합니다. [User lookup endpoint](/x-api/users/lookup/introduction)에서 확인할 수 있습니다.
  </Step>

  <Step title="메시지 전송">
    <CodeGroup dropdown>
      ```bash cURL theme={null}
      curl -X POST "https://api.x.com/2/dm_conversations/with/9876543210/messages" \
        -H "Authorization: Bearer $USER_ACCESS_TOKEN" \
        -H "Content-Type: application/json" \
        -d '{"text": "Hello! This is a message from the API."}'
      ```

      ```python title="Python SDK" lines wrap icon="python" theme={null}
      from xdk import Client

      client = Client(bearer_token="YOUR_USER_ACCESS_TOKEN")

      # Send a one-to-one message
      response = client.dm.send_message(
          participant_id="9876543210",
          text="Hello! This is a message from the API."
      )

      print(f"Message sent: {response.data.dm_event_id}")
      print(f"Conversation: {response.data.dm_conversation_id}")
      ```

      ```javascript title="JavaScript SDK" lines wrap icon="square-js" theme={null}
      import { Client } from "@xdevplatform/xdk";

      const client = new Client({ accessToken: "YOUR_USER_ACCESS_TOKEN" });

      // Send a one-to-one message
      const response = await client.dm.sendMessage({
        participantId: "9876543210",
        text: "Hello! This is a message from the API.",
      });

      console.log(`Message sent: ${response.data?.dm_event_id}`);
      console.log(`Conversation: ${response.data?.dm_conversation_id}`);
      ```
    </CodeGroup>
  </Step>

  <Step title="응답 확인">
    ```json theme={null}
    {
      "data": {
        "dm_conversation_id": "1234567890-9876543210",
        "dm_event_id": "1582103724607971332"
      }
    }
    ```
  </Step>
</Steps>

## 그룹 대화 생성

<Steps>
  <Step title="참가자 정의">
    그룹에 포함할 모든 사용자(본인 제외)의 user ID를 수집합니다.
  </Step>

  <Step title="첫 메시지와 함께 그룹 생성">
    <CodeGroup dropdown>
      ```bash cURL theme={null}
      curl -X POST "https://api.x.com/2/dm_conversations" \
        -H "Authorization: Bearer $USER_ACCESS_TOKEN" \
        -H "Content-Type: application/json" \
        -d '{
          "conversation_type": "Group",
          "participant_ids": ["944480690", "906948460078698496"],
          "message": {"text": "Welcome to our new group!"}
        }'
      ```

      ```python title="Python SDK" lines wrap icon="python" theme={null}
      from xdk import Client

      client = Client(bearer_token="YOUR_USER_ACCESS_TOKEN")

      # Create a group conversation
      response = client.dm.create_conversation(
          conversation_type="Group",
          participant_ids=["944480690", "906948460078698496"],
          message={"text": "Welcome to our new group!"}
      )

      print(f"Group created: {response.data.dm_conversation_id}")
      ```

      ```javascript title="JavaScript SDK" lines wrap icon="square-js" theme={null}
      import { Client } from "@xdevplatform/xdk";

      const client = new Client({ accessToken: "YOUR_USER_ACCESS_TOKEN" });

      // Create a group conversation
      const response = await client.dm.createConversation({
        conversationType: "Group",
        participantIds: ["944480690", "906948460078698496"],
        message: { text: "Welcome to our new group!" },
      });

      console.log(`Group created: ${response.data?.dm_conversation_id}`);
      ```
    </CodeGroup>
  </Step>

  <Step title="대화 ID 받기">
    ```json theme={null}
    {
      "data": {
        "dm_conversation_id": "1582103724607971328",
        "dm_event_id": "1582103724607971332"
      }
    }
    ```

    나중에 메시지를 추가하려면 `dm_conversation_id`를 저장해 두세요.
  </Step>
</Steps>

***

## 기존 대화에 메시지 추가

이미 참여 중인 대화에 메시지를 보냅니다:

<CodeGroup dropdown>
  ```bash cURL theme={null}
  curl -X POST "https://api.x.com/2/dm_conversations/1582103724607971328/messages" \
    -H "Authorization: Bearer $USER_ACCESS_TOKEN" \
    -H "Content-Type: application/json" \
    -d '{"text": "Adding another message to the conversation."}'
  ```

  ```python Python SDK theme={null}
  from xdk import Client

  client = Client(bearer_token="YOUR_USER_ACCESS_TOKEN")

  # Add message to existing conversation
  response = client.dm.send_message_to_conversation(
      dm_conversation_id="1582103724607971328",
      text="Adding another message to the conversation."
  )

  print(f"Message sent: {response.data.dm_event_id}")
  ```

  ```javascript JavaScript SDK theme={null}
  import { Client } from "@xdevplatform/xdk";

  const client = new Client({ accessToken: "YOUR_USER_ACCESS_TOKEN" });

  // Add message to existing conversation
  const response = await client.dm.sendMessageToConversation(
    "1582103724607971328",
    { text: "Adding another message to the conversation." }
  );

  console.log(`Message sent: ${response.data?.dm_event_id}`);
  ```
</CodeGroup>

## 미디어 첨부 메시지 전송

<Steps>
  <Step title="미디어 업로드">
    먼저 [Media Upload endpoint](/x-api/media/quickstart/media-upload-chunked)를 사용해 미디어를 업로드합니다.
  </Step>

  <Step title="미디어 첨부와 함께 전송">
    <CodeGroup dropdown>
      ```bash cURL theme={null}
      curl -X POST "https://api.x.com/2/dm_conversations/with/9876543210/messages" \
        -H "Authorization: Bearer $USER_ACCESS_TOKEN" \
        -H "Content-Type: application/json" \
        -d '{
          "text": "Check out this image!",
          "attachments": [{"media_id": "1234567890123456789"}]
        }'
      ```

      ```python title="Python SDK" lines wrap icon="python" theme={null}
      from xdk import Client

      client = Client(bearer_token="YOUR_USER_ACCESS_TOKEN")

      # Send message with media
      response = client.dm.send_message(
          participant_id="9876543210",
          text="Check out this image!",
          attachments=[{"media_id": "1234567890123456789"}]
      )

      print(f"Message with media sent: {response.data.dm_event_id}")
      ```

      ```javascript title="JavaScript SDK" lines wrap icon="square-js" theme={null}
      import { Client } from "@xdevplatform/xdk";

      const client = new Client({ accessToken: "YOUR_USER_ACCESS_TOKEN" });

      // Send message with media
      const response = await client.dm.sendMessage({
        participantId: "9876543210",
        text: "Check out this image!",
        attachments: [{ mediaId: "1234567890123456789" }],
      });

      console.log(`Message with media sent: ${response.data?.dm_event_id}`);
      ```
    </CodeGroup>
  </Step>
</Steps>

***

## 메시지 삭제

전송한 메시지를 삭제합니다:

<CodeGroup dropdown>
  ```bash cURL theme={null}
  curl -X DELETE "https://api.x.com/2/dm_events/1582103724607971332" \
    -H "Authorization: Bearer $USER_ACCESS_TOKEN"
  ```

  ```python Python SDK theme={null}
  from xdk import Client

  client = Client(bearer_token="YOUR_USER_ACCESS_TOKEN")

  # Delete a message
  response = client.dm.delete_message("1582103724607971332")
  print(f"Deleted: {response.data.deleted}")
  ```

  ```javascript JavaScript SDK theme={null}
  import { Client } from "@xdevplatform/xdk";

  const client = new Client({ accessToken: "YOUR_USER_ACCESS_TOKEN" });

  // Delete a message
  const response = await client.dm.deleteMessage("1582103724607971332");
  console.log(`Deleted: ${response.data?.deleted}`);
  ```
</CodeGroup>

**응답:**

```json theme={null}
{
  "data": {
    "deleted": true
  }
}
```

<Warning>
  본인이 전송한 메시지만 삭제할 수 있으며, 다른 참가자의 메시지는 삭제할 수 없습니다.
</Warning>

***

## 필수 scope

OAuth 2.0 PKCE를 사용할 때 access token에 다음 scope가 포함되어야 합니다:

| Scope        | 설명                      |
| :----------- | :---------------------- |
| `dm.write`   | 메시지 전송 및 삭제             |
| `dm.read`    | 대화 읽기 (dm.write와 함께 필수) |
| `tweet.read` | 일부 expansion에 필요        |
| `users.read` | 사용자 expansion에 필요       |
