title: Text Generator
|
||||
---
|
||||
|
||||
The text generation application offers non-session support and is ideal for translation, article writing, summarization AI, and more.
|
||||
|
||||
### Base URL
|
||||
|
||||
```text
|
||||
https://api.dify.ai/v1
|
||||
```
|
||||
|
||||
### Authentication
|
||||
|
||||
The Service API uses `API-Key` authentication.
|
||||
|
||||
<i>
|
||||
**Strongly recommend storing your API Key on the server-side, not shared or
|
||||
stored on the client-side, to avoid possible API-Key leakage that can lead
|
||||
to serious consequences.**
|
||||
</i>
|
||||
|
||||
For all API requests, include your API Key in the `Authorization` HTTP Header, as shown below:
|
||||
|
||||
```http
|
||||
Authorization: Bearer {API_KEY}
|
||||
```
|
||||

|
||||
|
||||
## POST /completion-messages
|
||||
|
||||
Create Completion Message
|
||||
|
||||
Send a request to the text generation application.
|
||||
|
||||
### Request Body
|
||||
|
||||
- `inputs` (object): Allows the entry of various variable values defined by the App.
|
||||
The `inputs` parameter contains multiple key/value pairs, with each key corresponding to a specific variable and each value being the specific value for that variable.
|
||||
The text generation application requires at least one key/value pair to be inputted.
|
||||
- `query` (string, Required): The input text, the content to be processed.
|
||||
- `response_mode` (string): The mode of response return, supporting:
|
||||
- `streaming`: Streaming mode (recommended), implements a typewriter-like output through SSE ([Server-Sent Events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events)).
|
||||
- `blocking`: Blocking mode, returns result after execution is complete. (Requests may be interrupted if the process is long)
|
||||
<i>
|
||||
Due to Cloudflare restrictions, the request will be interrupted
|
||||
without a return after 100 seconds.
|
||||
</i>
|
||||
- `user` (string): User identifier, used to define the identity of the end-user for retrieval and statistics. Should be uniquely defined by the developer within the application.
|
||||
- `files` (array[object]): File list, suitable for inputting files (images) combined with text understanding and answering questions, available only when the model supports Vision capability.
|
||||
- `type` (string): Supported type: `image` (currently only supports image type).
|
||||
- `transfer_method` (string): Transfer method, `remote_url` for image URL / `local_file` for file upload.
|
||||
- `url` (string): Image URL (when the transfer method is `remote_url`).
|
||||
- `upload_file_id` (string): Uploaded file ID, which must be obtained by uploading through the File Upload API in advance (when the transfer method is `local_file`).
|
||||
|
||||
### Response
|
||||
|
||||
When `response_mode` is `blocking`, return a CompletionResponse object.
|
||||
When `response_mode` is `streaming`, return a ChunkCompletionResponse stream.
|
||||
|
||||
#### ChatCompletionResponse
|
||||
|
||||
Returns the complete App result, `Content-Type` is `application/json`.
|
||||
|
||||
- `message_id` (string): Unique message ID.
|
||||
- `mode` (string): App mode, fixed as `completion`.
|
||||
- `answer` (string): Complete response content.
|
||||
- `metadata` (object): Metadata.
|
||||
- `usage` (Usage): Model usage information.
|
||||
- `retriever_resources` (array[RetrieverResource]): Citation and Attribution List.
|
||||
- `created_at` (int): Message creation timestamp, e.g., 1705395332.
|
||||
|
||||
#### ChunkChatCompletionResponse
|
||||
|
||||
Returns the stream chunks outputted by the App, `Content-Type` is `text/event-stream`.
|
||||
Each streaming chunk starts with `data:`, separated by two newline characters `\n\n`, as shown below:
|
||||
|
||||
```streaming Response
|
||||
data: {"event": "message", "task_id": "900bbd43-dc0b-4383-a372-aa6e6c414227", "id": "663c5084-a254-4040-8ad3-51f2a3c1a77c", "answer": "Hi", "created_at": 1705398420}\n\n
|
||||
```
|
||||
|
||||
The structure of the streaming chunks varies depending on the `event`:
|
||||
|
||||
- `event: message`: LLM returns text chunk event, i.e., the complete text is output in a chunked fashion.
|
||||
- `task_id` (string): Task ID, used for request tracking and the below Stop Generate API.
|
||||
- `message_id` (string): Unique message ID.
|
||||
- `answer` (string): LLM returned text chunk content.
|
||||
- `created_at` (int): Creation timestamp, e.g., 1705395332.
|
||||
- `event: message_end`: Message end event, receiving this event means streaming has ended.
|
||||
- `task_id` (string): Task ID, used for request tracking and the below Stop Generate API.
|
||||
- `message_id` (string): Unique message ID.
|
||||
- `metadata` (object): Metadata.
|
||||
- `usage` (Usage): Model usage information.
|
||||
- `retriever_resources` (array[RetrieverResource]): Citation and Attribution List.
|
||||
- `event: tts_message`: TTS audio stream event, that is, speech synthesis output. The content is an audio block in Mp3 format, encoded as a base64 string. When playing, simply decode the base64 and feed it into the player. (This message is available only when auto-play is enabled).
|
||||
- `task_id` (string): Task ID, used for request tracking and the stop response interface below.
|
||||
- `message_id` (string): Unique message ID.
|
||||
- `audio` (string): The audio after speech synthesis, encoded in base64 text content, when playing, simply decode the base64 and feed it into the player.
|
||||
- `created_at` (int): Creation timestamp, e.g.: 1705395332.
|
||||
- `event: tts_message_end`: TTS audio stream end event, receiving this event indicates the end of the audio stream.
|
||||
- `task_id` (string): Task ID, used for request tracking and the stop response interface below.
|
||||
- `message_id` (string): Unique message ID.
|
||||
- `audio` (string): The end event has no audio, so this is an empty string.
|
||||
- `created_at` (int): Creation timestamp, e.g.: 1705395332.
|
||||
- `event: message_replace`: Message content replacement event.
|
||||
When output content moderation is enabled, if the content is flagged, then the message content will be replaced with a preset reply through this event.
|
||||
- `task_id` (string): Task ID, used for request tracking and the below Stop Generate API.
|
||||
- `message_id` (string): Unique message ID.
|
||||
- `answer` (string): Replacement content (directly replaces all LLM reply text).
|
||||
- `created_at` (int): Creation timestamp, e.g., 1705395332.
|
||||
- `event: error`: Exceptions that occur during the streaming process will be output in the form of stream events, and reception of an error event will end the stream.
|
||||
- `task_id` (string): Task ID, used for request tracking and the below Stop Generate API.
|
||||
- `message_id` (string): Unique message ID.

title: テキスト ジェネレーター
|
||||
---
|
||||
|
||||
テキスト生成アプリケーションはセッションレスをサポートし、翻訳、記事作成、要約 AI 等に最適です。
|
||||
|
||||
### ベース URL
|
||||
|
||||
```text
|
||||
https://api.dify.ai/v1
|
||||
```
|
||||
|
||||
### 認証
|
||||
|
||||
サービス API は`API-Key`認証を使用します。
|
||||
**_API キーの漏洩による重大な結果を避けるため、API キーはサーバーサイドに保存し、クライアントサイドでは共有や保存しないことを強く推奨します。_**
|
||||
|
||||
すべての API リクエストで、以下のように`Authorization` HTTP ヘッダーに API キーを含めてください：
|
||||
|
||||
```text
|
||||
Authorization: Bearer {API_KEY}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||

|
||||
|
||||
- `inputs` (object)
|
||||
アプリで定義された各種変数値を入力できます。
|
||||
`inputs`パラメータには複数のキー/値ペアが含まれ、各キーは特定の変数に対応し、各値はその変数の具体的な値となります。
|
||||
テキスト生成アプリケーションでは、少なくとも 1 つのキー/値ペアの入力が必要です。
|
||||

|
||||
- `blocking` ブロッキングモード、実行完了後に結果を返却。（処理が長い場合はリクエストが中断される可能性があります）
|
||||
_Cloudflare の制限により、100 秒後に返却なしで中断されます。_
|
||||
- `user` (string)
|
||||
ユーザー識別子、エンドユーザーの身元を定義し、取得や統計に使用します。
|
||||
アプリケーション内で開発者が一意に定義する必要があります。
|
||||

|
||||
|
||||
#### ChunkChatCompletionResponse
|
||||
|
||||
アプリが出力するストリームチャンクを返却、`Content-Type`は`text/event-stream`です。
|
||||
各ストリーミングチャンクは`data:`で始まり、2 つの改行文字`\n\n`で区切られます：
|
||||
|
||||
```streaming
|
||||
data: {"event": "message", "task_id": "900bbd43-dc0b-4383-a372-aa6e6c414227", "id": "663c5084-a254-4040-8ad3-51f2a3c1a77c", "answer": "Hi", "created_at": 1705398420}\n\n
|
||||
```
|
||||
|
||||

title: 文本生成应用
|
||||
---
|
||||
|
||||
文本生成应用无会话支持，适合用于翻译/文章写作/总结 AI 等等。
|
||||
|
||||
### 基础 URL
|
||||
|
||||
```text
|
||||
https://api.dify.ai/v1
|
||||
```
|
||||
|
||||
### 鉴权
|
||||
|
||||
Dify Service API 使用 `API-Key` 进行鉴权。
|
||||
_强烈建议开发者把 `API-Key` 放在后端存储，而非分享或者放在客户端存储，以免 `API-Key` 泄露，导致财产损失。_
|
||||
所有 API 请求都应在 **`Authorization`** HTTP Header 中包含您的 `API-Key`，如下所示：
|
||||
|
||||
```text
|
||||
Authorization: Bearer {API_KEY}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## 发送消息
|
||||
|
||||
**POST** `/completion-messages`
|
||||
|
||||
发送请求给文本生成型应用。
|
||||
|
||||
### Request Body
|
||||
|
||||
- **`inputs`** (`object`): (选填) 允许传入 App 定义的各变量值。inputs 参数包含了多组键值对（Key/Value pairs），每组的键对应一个特定变量，每组的值则是该变量的具体值。文本生成型应用要求至少传入一组键值对。
|
||||
- **`query`** (`string`): 必填. 用户输入的文本内容。
|
||||
- **`response_mode`** (`string`):
|
||||
- `streaming`: 流式模式（推荐）。基于 SSE（**[Server-Sent Events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events)**）实现类似打字机输出方式的流式返回。
|
||||
- `blocking`: 阻塞模式，等待执行完毕后返回结果。（请求若流程较长可能会被中断）。
|
||||
_由于 Cloudflare 限制，请求会在 100 秒超时无返回后中断。_
|
||||
- **`user`** (`string`): 用户标识，用于定义终端用户的身份，方便检索、统计。由开发者定义规则，需保证用户标识在应用内唯一。
|
||||
- **`files`** (`array[object]`): 上传的文件。
|
||||
- **`type`** (`string`): 支持类型：图片 `image`（目前仅支持图片格式）。
|
||||
- **`transfer_method`** (`string`): 传递方式:
|
||||
- `remote_url`: 图片地址。
|
||||
- `local_file`: 上传文件。
|
||||
- **`url`** (`string`): 图片地址。（仅当传递方式为 `remote_url` 时）。

||||
|
||||
### Response
|
||||
|
||||
当 `response_mode` 为 `blocking` 时，返回 ChatCompletionResponse object。
|
||||
当 `response_mode` 为 `streaming`时，返回 ChunkChatCompletionResponse object 流式序列。
|
||||
|
||||
#### ChatCompletionResponse
|
||||
|
||||
返回完整的 App 结果，`Content-Type` 为 `application/json`。
|
||||

|
||||
|
||||
#### ChunkChatCompletionResponse
|
||||
|
||||
返回 App 输出的流式块，`Content-Type` 为 `text/event-stream`。
|
||||
每个流式块均为 data: 开头，块之间以 `\n\n` 即两个换行符分隔，如下所示：
|
||||
|
||||
```text
|
||||
data: {"event": "message", "task_id": "900bbd43-dc0b-4383-a372-aa6e6c414227", "id": "663c5084-a254-4040-8ad3-51f2a3c1a77c", "answer": "Hi", "created_at": 1705398420}\n\n
|
||||
```
|
||||
|
||||
流式块中根据 `event` 不同，结构也不同：
|
||||
|
||||
- `event: message`: LLM 返回文本块事件，即：完整的文本以分块的方式输出。
|
||||
- **`task_id`** (`string`): 任务 ID，用于请求跟踪和下方的停止响应接口

||||
- **`retriever_resources`** (`array[RetrieverResource]`): 引用和归属分段列表
|
||||
- `event: tts_message`: TTS 音频流事件，即：语音合成输出。内容是 Mp3 格式的音频块，使用 base64 编码后的字符串，播放的时候直接解码即可。(开启自动播放才有此消息)
|
||||
- **`task_id`** (`string`): 任务 ID，用于请求跟踪和下方的停止响应接口
|
||||
- **`message_id`** (`string`): 消息唯一 ID
|
||||
- **`audio`** (`string`): 语音合成之后的音频块使用 Base64 编码之后的文本内容，播放的时候直接 base64 解码送入播放器即可
|
||||
- **`created_at`** (`int`): 创建时间戳，如：1705395332
|
||||
- `event: tts_message_end`: TTS 音频流结束事件，收到这个事件表示音频流返回结束。
|
||||
- **`task_id`** (`string`): 任务 ID，用于请求跟踪和下方的停止响应接口
|
||||
- **`message_id`** (`string`): 消息唯一 ID
|
||||
- **`audio`** (`string`): 结束事件是没有音频的，所以这里是空字符串
|
||||
- **`created_at`** (`int`): 创建时间戳，如：1705395332
|
||||
- `event: message_replace`: 消息内容替换事件。
|
||||
开启内容审查和审查输出内容时，若命中了审查条件，则会通过此事件替换消息内容为预设回复。
|
||||
- **`task_id`** (`string`): 任务 ID，用于请求跟踪和下方的停止响应接口
|
||||
- **`message_id`** (`string`): 消息唯一 ID
|
||||
- **`answer`** (`string`): 替换内容（直接替换 LLM 所有回复文本）
|
||||
- **`created_at`** (`int`): 创建时间戳，如：1705395332
|
||||
- `event: error`:
|
||||
流式输出过程中出现的异常会以 stream event 形式输出，收到异常事件后即结束。
|
||||
- **`task_id`** (`string`): 任务 ID，用于请求跟踪和下方的停止响应接口
|
||||
- **`message_id`** (`string`): 消息唯一 ID

title: Workflow
|
||||
---
|
||||
|
||||
Workflow applications offers non-session support and is ideal for translation, article writing, summarization AI, and more.
|
||||
|
||||
### Base URL
|
||||
|
||||
The Base URL for the API is:
|
||||
|
||||
```text
|
||||
https://api.dify.ai/v1
|
||||
```
|
||||
|
||||
### Authentication
|
||||
|
||||
The Service API uses `API-Key` authentication.
|
||||
|
||||
<i>
|
||||
**Strongly recommend storing your API Key on the server-side, not shared or
|
||||
stored on the client-side, to avoid possible API-Key leakage that can lead
|
||||
to serious consequences.**
|
||||
</i>
|
||||
|
||||
For all API requests, include your API Key in the `Authorization` HTTP Header, as shown below:
|
||||
|
||||
```text Authorization Header
|
||||
Authorization: Bearer {API_KEY}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## Execute Workflow (POST /workflows/run)
|
||||
|
||||
Execute workflow, cannot be executed without a published workflow.
|
||||
|
||||
<CodeGroup>
|
||||
```bash cURL
|
||||
curl -X POST 'https://api.dify.ai/v1/workflows/run' \
|
||||
--header 'Authorization: Bearer {api_key}' \
|
||||
--header 'Content-Type: application/json' \
|
||||
--data-raw '{
|
||||
"inputs": {"your_key": "your_value"},
|
||||
"response_mode": "streaming",
|
||||
"user": "abc-123"
|
||||
}'
|
||||
```
|
||||
</CodeGroup>
|
||||
|
||||
### Request Body
|
||||
|
||||
- `inputs` (object) Required
|
||||
Allows the entry of various variable values defined by the App.
|
||||
The `inputs` parameter contains multiple key/value pairs, with each key corresponding to a specific variable and each value being the specific value for that variable.
|
||||
The workflow application requires at least one key/value pair to be inputted. The variable can be of File Array type.
|
||||
File Array type variable is suitable for inputting files combined with text understanding and answering questions, available only when the model supports file parsing and understanding capability.
|
||||
If the variable is of File Array type, the corresponding value should be a list whose elements contain following attributions:
|
||||
|
||||
- `type` (string) Supported type:
|
||||
- `document` ('TXT', 'MD', 'MARKDOWN', 'PDF', 'HTML', 'XLSX', 'XLS', 'DOCX', 'CSV', 'EML', 'MSG', 'PPTX', 'PPT', 'XML', 'EPUB')
|
||||
- `image` ('JPG', 'JPEG', 'PNG', 'GIF', 'WEBP', 'SVG')
|
||||
- `audio` ('MP3', 'M4A', 'WAV', 'WEBM', 'AMR')
|
||||
- `video` ('MP4', 'MOV', 'MPEG', 'MPGA')
|
||||
- `custom` (Other file types)
|
||||
- `transfer_method` (string) Transfer method, `remote_url` for image URL / `local_file` for file upload
|
||||
- `url` (string) Image URL (when the transfer method is `remote_url`)
|
||||
- `upload_file_id` (string) Uploaded file ID, which must be obtained by uploading through the File Upload API in advance (when the transfer method is `local_file`)
|
||||
|
||||
- `response_mode` (string) Required
|
||||
The mode of response return, supporting:
|
||||
- `streaming` Streaming mode (recommended), implements a typewriter-like output through SSE ([Server-Sent Events](https://developer.mozilla.org/en-US/docs/Web/API/Server-sent_events/Using_server-sent_events)).
|
||||
- `blocking` Blocking mode, returns result after execution is complete. (Requests may be interrupted if the process is long)
|
||||
<i>
|
||||
Due to Cloudflare restrictions, the request will be interrupted
|
||||
without a return after 100 seconds.
|
||||
</i>
|
||||
- `user` (string) Required
|
||||
User identifier, used to define the identity of the end-user for retrieval and statistics.
|
||||
Should be uniquely defined by the developer within the application.
|
||||
|
||||
#### Example: file array as an input variable
|
||||
|
||||
```json "File variable example"
|
||||
{
|
||||
"inputs": {
|
||||
"{variable_name}": [
|
||||
{
|
||||
"transfer_method": "local_file",
|
||||
"upload_file_id": "{upload_file_id}",
|
||||
"type": "{document_type}"
|
||||
}
|
||||
]
|
||||
}
|
||||
}
|
||||
```
|
||||
|
||||
### Responses
|
||||
|
||||
When `response_mode` is `blocking`, return a CompletionResponse object.
|
||||

title: ワークフロー
|
||||
---
|
||||
|
||||
ワークフローアプリケーションは、セッションをサポートせず、翻訳、記事作成、要約 AI などに最適です。
|
||||
|
||||
### ベース URL
|
||||
|
||||
```text
|
||||
https://api.dify.ai/v1
|
||||
```
|
||||
|
||||
### 認証
|
||||
|
||||
サービス API は`API-Key`認証を使用します。
|
||||
|
||||
<i>
|
||||
**APIキーの漏洩を防ぐため、APIキーはクライアント側で共有または保存せず、サーバー側で保存することを強くお勧めします。**
|
||||
</i>
|
||||
|
||||
すべての API リクエストにおいて、以下のように`Authorization`HTTP ヘッダーに API キーを含めてください：
|
||||
|
||||
```text
|
||||
Authorization: Bearer {API_KEY}
|
||||
```
|
||||
|
||||
---
|
||||
|
||||
## POST /workflows/run ワークフローを実行

アプリで定義されたさまざまな変数値の入力を許可します。
|
||||
`inputs`パラメータには複数のキー/値ペアが含まれ、各キーは特定の変数に対応し、各値はその変数の特定の値です。
|
||||
ワークフローアプリケーションは少なくとも 1 つのキー/値ペアの入力を必要とします。値はファイルリストである場合もあります。
|
||||
ファイルリストは、テキスト理解と質問への回答を組み合わせたファイルの入力に適しています。モデルがファイルの解析と理解機能をサポートしている場合にのみ使用できます。
|
||||
|
||||
変数がファイルリストの場合、リストの各要素は以下の属性を持つ必要があります。
|
||||
|
||||
- `type` (string) サポートされているタイプ:
|
||||

### Authentication
|
||||
|
||||
Dify Service API 使用 `API-Key` 进行鉴权。
|
||||
<i>**强烈建议开发者把 `API-Key` 放在后端存储，而非分享或者放在客户端存储，以免 `API-Key` 泄露，导致财产损失。**</i>
|
||||
所有 API 请求都应在 **`Authorization`** HTTP Header 中包含您的 `API-Key`，如下所示：
|
||||
|
||||
```text
|
||||
Authorization: Bearer {API_KEY}
|
||||
```
