Chat API

FastGPT OpenAPI Chat Interface

How to Get AppId

You can find the AppId in your application details URL.

Start a Conversation

  • This API requires an application-specific API key, or it will return an error.
  • Some packages require adding v1 to the BaseUrl. If you get a 404 error, try adding v1 and retry.

Request Chat Agent and Workflow

The v1 chat API is compatible with the GPT interface! If you're using the standard GPT official API, you can access FastGPT by simply changing the BaseUrl and Authorization. However, note these rules:

  • Parameters like model and temperature are ignored. These values are determined by your workflow configuration.
  • Won't return actual Token consumed. If needed, set detail=true and manually calculate tokens from responseData.

Request

curl --location --request POST 'http://localhost:3000/api/v1/chat/completions' \
--header 'Authorization: Bearer fastgpt-xxxxxx' \
--header 'Content-Type: application/json' \
--data-raw '{
"chatId": "my_chatId",
"stream": false,
"detail": false,
"responseChatItemId": "my_responseChatItemId",
"variables": {
    "uid": "asdfadsfasfd2323",
    "name": "张三"
},
"messages": [
    {
        "role": "user",
        "content": "导演是谁"
    }
]
}'
  • Only messages differs slightly; other parameters are the same.
  • Direct file uploads are not supported. Upload files to your object storage and provide the URL.
curl --location --request POST 'http://localhost:3000/api/v1/chat/completions' \
--header 'Authorization: Bearer fastgpt-xxxxxx' \
--header 'Content-Type: application/json' \

                }
            ]
        }
    ]
}'
  • headers.Authorization: Bearer [apikey]
  • chatId: string | undefined 。
    • 为时（不传入），不使用 FastGpt 提供的上下文功能，完全通过传入的 messages 构建上下文。
    • 为非空字符串时，意味着使用 chatId 进行对话，自动从 FastGpt 数据库取历史记录，并使用 messages数组最后一个内容作为用户问题，其余 message 会被忽略。请自行确保 chatId唯一，长度小于250，通常可以是自己系统的对话框ID。
  • messages: 结构与GPT接口 chat模式一致。
  • responseChatItemId: string | undefined 。如果传入，则会将该值作为本次对话的响应消息的 ID，FastGPT会自动将该 ID 存入数据库。请确保，在当前chatId下，responseChatItemId是唯一的。
  • detail:是否返回中间值（模块状态，响应的完整结果等），stream模式下会通过event进行区分，非stream模式结果保存在responseData中。
  • variables: 模块变量，一个对象，会替换模块中，输入框内容里的[key]

Response

If your workflow contains interactive nodes, still call this API with detail=true. Get interactive node config from event=interactive data. For stream=false, find type=interactive elements in choices.

When calling a workflow with interactive nodes, if an interactive node is encountered, it returns immediately with this info:

{
  "interactive": {
    "type": "userSelect",
    "params": {
      "description": "测试",
      "userSelectOptions": [
        {
          "value": "Confirm",
          "key": "option1"
        },
        {
          "value": "Cancel",
          "key": "option2"
        }
      ]
    }
  }
}
{
  "interactive": {
    "type": "userInput",
    "params": {
      "description": "测试",
      "inputForm": [
        {
          "type": "input",
          "key": "测试 1",
          "label": "测试 1",
          "description": "",
          "value": "",
          "defaultValue": "",
          "valueType": "string",
          "required": false,
          "list": [
            {
              "label": "",
              "value": ""
            }
          ]
        },
        {
          "type": "numberInput",
          "key": "测试 2",
          "label": "测试 2",
          "description": "",
          "value": "",
          "defaultValue": "",
          "valueType": "number",
          "required": false,
          "list": [
            {
              "label": "",
              "value": ""
            }
          ]
        }
      ]
    }
  }
}

Continue Interactive Node

After receiving interactive node info, render your UI to guide user input or selection. Then call this API again to continue the workflow. Use this format:

For user selection, simply pass the selected value to messages.

curl --location --request POST 'http://localhost:3000/api/v1/chat/completions' \
--header 'Authorization: Bearer fastgpt-xxx' \
--header 'Content-Type: application/json' \
--data-raw '{
    "stream": true,
    "detail": true,
    "chatId":"22222231",
    "messages": [
        {
            "role": "user",
            "content": "Confirm"
        }
    ]
}'

Form input is slightly more complex. Serialize the input as a JSON string for messages. Object keys match form keys, values are user inputs. Ensure chatId is consistent.

curl --location --request POST 'http://localhost:3000/api/v1/chat/completions' \
--header 'Authorization: Bearer fastgpt-xxxx' \
--header 'Content-Type: application/json' \
--data-raw '{
    "stream": true,
    "detail": true,
    "chatId":"22231",
    "messages": [
        {
            "role": "user",
            "content": "{\"测试 1\":\"这是输入框的内容\",\"测试 2\":666}"
        }
    ]
}'

Request Plugin

Plugin API is identical to chat API, with slight parameter differences:

  • 调用插件Type的应用时，接口默认为detail模式。
  • No need to pass chatId since plugins run only once.
  • No need to pass messages.
  • Pass variables to represent plugin inputs.
  • Get plugin outputs from pluginData.

Request

curl --location --request POST 'http://localhost:3000/api/v1/chat/completions' \
--header 'Authorization: Bearer test-xxxxx' \
--header 'Content-Type: application/json' \
--data-raw '{
    "stream": false,
    "chatId": "test",
    "variables": {
        "query":"你好" # 我的插件输入有一个参数，变量名叫 query
    }
}'

Response

  • Find plugin output by locating moduleType=pluginOutput in responseData. Its pluginOutput contains the output.
  • Stream output is still available via choices.

  • Get plugin output by deserializing the event=flowResponses string into an array. Find moduleType=pluginOutput element; its pluginOutput contains the output.
  • Stream output works the same as chat API.
