Postman CLI Release Notes

What's New

Support for running performance tests

Running performance tests using the Postman CLI is available as a beta feature.

The Postman CLI now supports configuring and running performance tests against collections in your team. Performance tests enable you to simulate real-world traffic to your APIs and automatically surface performance issues before changes reach production. With the Postman CLI, you can integrate performance tests into your CI/CD pipeline and ensure your APIs stay fast and reliable with every release. The Postman CLI sends the results to the Postman cloud to help you debug performance test results.

What's New

Syntax validation for API specifications

The postman spec lint command now includes dedicated syntax validation. Previously, specs with syntax errors would display a generic message like "Unable to lint. Please check your specification for errors." Now you see the exact syntax errors with file names, line numbers, and clear descriptions, making it much easier to fix issues in your OpenAPI specifications.

New "Issue Type" column in output

Validation results now include an "Issue Type" column that distinguishes between Syntax errors (structural/parsing issues) and Governance violations (rule-based issues). This helps you quickly identify and prioritize what to fix first.

The new column is added at the end of CSV, JSON, and table outputs to maintain backward compatibility with existing CI/CD pipelines.

Fixed collection push failing due to owner ID mismatch

Fixed an issue where postman workspace push would fail to update collections when the resource ID format didn't include the expected owner prefix.
