Runway Install Auth

Overview

Install the Runway ML SDK and configure API key authentication for AI video generation.

Prerequisites

• Runway account at runwayml.com
• API key from the Runway Developer Portal (dev.runwayml.com)
• Python 3.9+ or Node.js 18+

Instructions

Step 1: Install SDK

set -euo pipefail
# Python
pip install runwayml

# Node.js
npm install @runwayml/sdk

Step 2: Configure Environment

# .env
RUNWAYML_API_SECRET=key_xxxxxxxxxxxxxxxxxxxxxxxx

Step 3: Verify Connection (Python)

from runwayml import RunwayML

client = RunwayML()  # Reads RUNWAYML_API_SECRET from env

# The client is ready — no explicit auth call needed
# SDK auto-authenticates on first API call
print("RunwayML client initialized")

Step 4: Verify Connection (Node.js)

import RunwayML from '@runwayml/sdk';

const runway = new RunwayML();  // Reads RUNWAYML_API_SECRET from env
console.log('RunwayML client initialized');

Output

• runwayml SDK installed
• API key configured via environment variable
• Client ready for video generation
