Add allowed IP addresses for each API key on the Developers → API Keys page in the Dashboard. 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.
