To find your API key on QRZ.com, you must first have an active XML Logbook Data subscription. The API key for your online logbook is located within its settings. Steps to find your QRZ.com logbook API key: Log in to your account on QRZ.com. Navigate to your "Logbook". Click the "Settings" button, located in the upper-right corner of the logbook page. In the Settings menu, find the "QRZ Logbook API" section. Your API key will be blurred out for security. Click the "Show" button next to it to display the full key. Important to know: You must be a paid QRZ XML subscriber to get and use an API key. The key is tied to your logbook and grants read/write access to your log records. Keep your API key private, as it acts like a password for applications that integrate with your QRZ logbook. Dave W7UUU
