API monitoring continually tests endpoints to verify uptime, performance, and correctness of responses. It helps detect slow or failing APIs before they impact connected applications or users.

Uptrends monitors API requests, responses, and dependencies, giving you detailed insight into which step or service failed. You can view response codes, payloads, and timing per request to pinpoint where errors start, including with third-party APIs.

Yes! There’s no need to duplicate your work. You can import Postman collections directly into Uptrends and turn them into active API monitors. That means you can reuse your existing test logic, validate results continuously, and manage everything from one place.

Uptrends uses real browsers to run page tests, recording JavaScript exceptions and console logs, and flagging rendering issues that can break user interactions. You’ll see visual proof (including screenshots and waterfall data) for faster troubleshooting.

Uptrends supports API authentication methods such as OAuth. You can securely store credentials in encrypted vaults and validate both public and protected endpoints automatically.

When a check fails, Uptrends shows complete request-response details. That includes headers, payloads, timing, and status codes. You can quickly verify if the issue came from a bad redirect, CORS configuration, or external service dependency.
