Click the "Console" button in the bottom-left corner of the Postman window, or use the keyboard shortcut Cmd+Alt+C on Mac or Ctrl+Alt+C on Windows. This opens the Postman Console in a separate panel where you can see detailed logs of all HTTP requests and responses. The console shows raw request headers, response headers, cookies, status codes, timing data, and any errors that occurred during the request. If you're debugging API integrations for tracking pixels, Google Analytics Measurement Protocol calls, or server-side events, the console is essential because it reveals what's actually being sent versus what you think you configured in the request builder. You'll see two types of logs: request logs that show what Postman sent to the server, and response logs that show what came back. Each entry is timestamped and includes the full URL, method (GET, POST, etc.), and status code. Click any request in the console to expand it and see headers, body content, and response time in milliseconds. At Ottawa SEO, we use the Postman console constantly when setting up server-side Google Analytics 4 events or testing webhook endpoints for client tracking infrastructure. The console catches issues that don't show up in the main response viewer, like redirect chains, authentication token problems, or malformed JSON payloads that still return 200 OK but don't process correctly. One thing to watch: the console accumulates logs across sessions until you clear it manually using the trash icon. If you're running hundreds of test requests, it gets cluttered fast. Also, the console won't capture requests from Collection Runner or Newman (Postman's CLI) by default—you need to explicitly enable logging in those tools. For production API monitoring, we don't rely on Postman's console; we use proper logging infrastructure, but for dev and QA work on tracking implementations, it's the fastest way to see what's actually happening on the wire.
