Figma API Integration

Extract design data, generate code from components, and automate design workflows with Figma's API.

Quick Start

Authentication

typescript

const FIGMA_TOKEN = process.env.FIGMA_TOKEN;

const headers = {
  'X-Figma-Token': FIGMA_TOKEN
};

// Get file
const response = await fetch(
  `https://api.figma.com/v1/files/${FILE_KEY}`,
  { headers }
);

File Key & Node IDs

typescript

// Extract from Figma URL: figma.com/file/FILE_KEY/Name?node-id=NODE_ID
const figmaUrl = 'https://www.figma.com/file/abc123/MyDesign?node-id=1%3A2';
const fileKey = figmaUrl.match(/file\/([^/]+)/)?.[1];  // abc123
const nodeId = new URL(figmaUrl).searchParams.get('node-id');  // 1:2

Core API Endpoints

Get File

typescript

// Full file
GET https://api.figma.com/v1/files/:file_key

// With geometry for SVG paths
GET https://api.figma.com/v1/files/:file_key?geometry=paths

// Get component sets (variants)
GET https://api.figma.com/v1/files/:file_key/component_sets

// Get team's published components
GET https://api.figma.com/v1/teams/:team_id/components

Export Images

typescript
