Postman Monitors enable you to continuously check the health and performance of your APIs. You can create monitors that run requests in selected collections. Requests can run API test scripts, chain together multiple requests, and more. You can also schedule how often Postman runs monitored collections.
You’ll be alerted to any test failures once the monitor is running, so you can identify and address issues before your API’s consumers are affected.
Postman Monitors enable you to automatically run a collection of API requests from the Postman cloud on a schedule or when triggered by the Postman CLI. You can set up a monitor by selecting a collection and defining how it’ll run. For common scenarios, see monitor use cases.
By default, monitors run from the Postman cloud. For more options:
After your monitors run, you can view monitor results to analyze performance and debug issues. You can also publish monitor reports to share read-only results with stakeholders outside your workspace. To manage usage, see monitor usage.
For Enterprise teams, you can also get a unified view of your monitors alongside other API health metrics in the API Catalog, which provides centralized monitoring and governance across your organization’s APIs. To learn more about connecting your monitors to the API Catalog, see Set up a monitor.
If you run into issues, see how to troubleshoot monitors in Postman.
Monitors run Postman requests and scripts, enabling you to monitor APIs in a variety of ways. Common use cases include:
Detect issues during and after deployments - Run monitors on a schedule or trigger them using the Postman CLI to catch failures or performance regressions early, helping you resolve issues before they impact users.
Ensure API health and reliability over time - Continuously check that your APIs are available and responding within acceptable time thresholds across environments.
Test critical user workflows - Simulate real-world scenarios by chaining requests together to validate multi-step flows and ensure different parts of your API work together correctly.
Run tests across environments and regions - Ensure your APIs behave consistently by running monitors in different environments and geographic regions. (Manually selecting multiple regions requires a paid Postman plan.)
Identify potential security issues - Continuously test your APIs for common vulnerabilities by running security checks.
Track performance trends over time - Use monitor results to observe changes in response times and reliability, helping you identify patterns and diagnose issues.
For more examples of monitors in action, visit the Postman API Monitoring Examples public workspace to find example collections for some common monitoring use cases. You can collaborate on the collections in the workspace by creating a fork, or customize the collections for your team’s use by exporting and importing them into your internal workspace.
