# Workflow App API

Workflow applications offers non-session support and is ideal for translation, article writing, summarization AI, and more.

<div>
  ### Base URL
  <CodeGroup title="Code" targetCode={props.appDetail.api_base_url} />

  ### 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:

  <CodeGroup title="Code" targetCode='Authorization: Bearer {API_KEY}' />
</div>

---

<Heading
  url='/workflows/run'
  method='POST'
  title='Execute Workflow'
  name='#Execute-Workflow'
/>
<Row>
  <Col>
    Execute workflow, cannot be executed without a published workflow.

    ### 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.
        <br/>
        <i>The user identifier should be consistent with the user passed in the message sending interface. The Service API does not share conversations created by the WebApp.</i>
      - `files` (array[object]) Optional
      - `trace_id` (string) Optional
        Trace ID. Used for integration with existing business trace components to achieve end-to-end distributed tracing. If not provided, the system will automatically generate a trace_id. Supports the following three ways to pass, in order of priority:
        1. Header: via HTTP Header `X-Trace-Id`, highest priority.
        2. Query parameter: via URL query parameter `trace_id`.
        3. Request Body: via request body field `trace_id` (i.e., this field).

    ### Response
    When `response_mode` is `blocking`, return a CompletionResponse object.
    When `response_mode` is `streaming`, return a ChunkCompletionResponse stream.

    Execute a specific version of workflow by specifying the workflow ID in the path parameter.

    ### Path
          - `workflow_id` (string) Required Workflow ID to specify a specific version of workflow

      How to obtain: In the version history interface, click the copy icon on the right side of each version entry to copy the complete workflow ID. Each version entry contains a copyable ID field.

    ### 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')

      - `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.

      - `files` (array[object]) Optional
      - `trace_id` (string) Optional
        Trace ID. Used for integration with existing business trace components to achieve end-to-end distributed tracing. If not provided, the system will automatically generate a trace_id. Supports the following three ways to pass, in order of priority:
        1. Header: via HTTP Header `X-Trace-Id`, highest priority.
        2. Query parameter: via URL query parameter `trace_id`.
        3. Request Body: via request body field `trace_id` (i.e., this field).
