Instructions

Step 1: Install SDK

# Python
pip install supabase

Step 2: Configure Authentication

# Set environment variable
export SUPABASE_API_KEY="your-api-key"

# Or create .env file
echo 'SUPABASE_API_KEY=your-api-key' >> .env

Step 3: Verify Connection

const result = await supabase.from('_test').select('*').limit(1); console.log(result.error ? 'Failed' : 'OK');

Output

• Installed SDK package in node_modules or site-packages
• Environment variable or .env file with API key
