Source Location

The dataset creation API functions are defined in packages/ui/src/api/dataset.js. The createDataset function is at line 7, and createDatasetRow is at line 12.

Signature

// packages/ui/src/api/dataset.js:L7
const createDataset = (body) => client.post(`/datasets/set`, body)

// packages/ui/src/api/dataset.js:L12
const createDatasetRow = (body) => client.post(`/datasets/rows`, body)

The API client is configured at packages/ui/src/api/client.js with a base URL of ${baseURL}/api/v1, making the full endpoints:

• POST /api/v1/datasets/set for dataset creation
• POST /api/v1/datasets/rows for row creation

Import

import datasetApi from '@/api/dataset'

Creating a New Dataset

import datasetApi from '@/api/dataset'

// Create a new evaluation dataset
const response = await datasetApi.createDataset({
    name: 'Customer Support QA',
    description: 'Test cases for customer support chatflow evaluation'
})
const datasetId = response.data.id

Adding Individual Rows

import datasetApi from '@/api/dataset'
