Generate API Keys

Locate API Keys​

  1. Log into dashboard.stendly.com
  2. Navigate to API Keys in the sidebar
  3. Click Generate New Key

Key Format​

All API keys use the st_live_ prefix. Select the target environment when initializing the SDK:

PrefixEnvironmentUsage
st_live_mainnetProduction payments
st_live_devnetDevelopment/testing

Security Best Practices​

  • Never commit API keys to version control
  • Use environment variables or a secret manager
  • Rotate keys regularly (every 90 days recommended)
  • Use separate keys for development and production
  • Revoke compromised keys immediately from the dashboard

Good​

import os
client = Client(api_key=os.environ["STENDLY_API_KEY"])

Bad​

client = Client(api_key="st_live_xxxxxxxxx")  # ❌ Never hardcode
