What’s new in Postman: AsyncAPI 3.0, performance streaming, and service accounts

Postman has introduced several new features aimed at enhancing the API lifecycle, including first-class support for AsyncAPI 3.0, which is crucial for event-driven systems using technologies like Kafka, MQTT, and WebSockets. The update allows users to create, validate, and manage AsyncAPI 3.0 specifications with ease, providing a unified editing and preview experience similar to OpenAPI. Additionally, a centralized diagnostics pane now consolidates validation issues across open API specifications, enabling more efficient error management. Users can also move API specifications between workspaces, simplifying reorganization without duplication. A new live streaming feature for CLI performance runs allows real-time monitoring of API tests, reducing wasted time in CI/CD pipelines by providing immediate feedback on performance issues. The Postman CLI can act as an automated quality gate, enforcing performance thresholds to prevent regressions from reaching production. For enterprise teams, service accounts provide a secure, non-human identity for automation and system interactions, mitigating risks associated with personal API keys. Collectively, these updates demonstrate Postman's focus on improving feedback loops, protocol coverage, and automation infrastructure, particularly in hybrid architectures combining REST and event-driven services.
