Hex Install & Auth

Overview

Configure Hex API authentication using OAuth 2.0 Bearer tokens. The Hex API at app.hex.tech/api/v1/ lets you programmatically trigger project runs, check status, manage users, and configure connections. Tokens are generated per-user in the Hex workspace settings.

Prerequisites

Hex account (Team or Enterprise plan)
Workspace admin access for API token generation
At least one published Hex project

Instructions

Step 1: Generate API Token

Open Hex workspace settings
Navigate to API tokens section
Click New Token
Set description and expiration
Select scopes: "Read projects" and/or "Run projects"

Step 2: Configure Environment

# .env (NEVER commit)
HEX_API_TOKEN=hex_token_abc123...
HEX_WORKSPACE_URL=https://app.hex.tech

# .gitignore
.env
.env.local

Step 3: Verify Connection

// verify-hex.ts
import 'dotenv/config';

const TOKEN = process.env.HEX_API_TOKEN!;

async function verify() {
  const response = await fetch('https://app.hex.tech/api/v1/projects', {
    headers: { 'Authorization': `Bearer ${TOKEN}`, 'Content-Type': 'application/json' },
  });
  if (!response.ok) throw new Error(`Hex API ${response.status}`);
  const projects = await response.json();
  console.log(`Connected! Found ${projects.length} projects`);
  return projects;
}

verify().catch(console.error);

# curl verification
curl -s -H "Authorization: Bearer $HEX_API_TOKEN" \
  https://app.hex.tech/api/v1/projects | python3 -m json.tool
