1
Create a Lumx account
Sign up at the Dashboard. From there you can manage projects, generate API keys, and monitor transaction activity.
New accounts start with a Sandbox environment for testing. To access Production, schedule a call with our team.
2
Generate your API key
Navigate to Developers → API Keys and create a new key for your project.Copy your API key immediately. It’s only shown once. If compromised, revoke and rotate from the Dashboard.
Store your API keys securely. Never commit them to version control or expose them in client-side code.
3
Allowlist your server IPs
Add the IP addresses your servers call the API from on the Developers → API Keys page. The allowlist applies to production only (
https://api.lumx.io), sandbox stays open to requests from any IP. During the current grace period nothing is blocked, even for keys that already have an allowlist. Enforcement starts on September 21, 2026, when the production API begins rejecting requests from IPs outside the allowlist, so register your server IPs before then.
