Or download single file:

curl -O https://raw.githubusercontent.com/fcsapi/token-generator/main/token-generator.php
curl -O https://raw.githubusercontent.com/fcsapi/token-generator/main/token-generator.py
# ... etc

Quick Start

PHP:

$generator = new FcsTokenGenerator('access_key', 'public_key');
$tokenData = $generator->generateToken();

Python:

generator = FcsTokenGenerator('access_key', 'public_key')
token_data = generator.generate_token()

JavaScript:

const generator = new FcsTokenGenerator('access_key', 'public_key');
const tokenData = generator.generateToken();

Token Expiry Options

• 300 seconds (5 minutes)
• 900 seconds (15 minutes)
• 1800 seconds (30 minutes)
• 3600 seconds (1 hour - default)
• 86400 seconds (24 hours)

Use Case

Generate secure tokens on backend (PHP, Python, etc.) → Send to frontend → Frontend uses token for FCS API calls (no API key exposed in browser).

Requirements

• Backend server (any of the 10 supported languages)
• FCS API Access Key and Public Key
