Postman App Updates & Release Notes

May 20, 2026

What’s New

Introducing service account identities for automation and integrations

Available on Enterprise plans

System service accounts give your team a dedicated, non-human identity for automation, integrations, and system-to-system interactions. Instead of tying CI/CD pipelines or backend services to a person's credentials, you can create a service account that represents the system itself with its own access controls, credentials, and audit trail.

To learn more, see Manage service account identities for automation and integrations.

Improvements

Improved visibility for syntax errors and governance issues in Spec Hub

Spec Hub now has a unified Issues tab below the specification editor, making it easier to view and navigate validation results. Syntax errors and governance rule violations are organized into expandable sections, with details and direct links to their location in your specification.

To learn more, see Validate an API specification.

Bug Fixes

Fixed an issue that prevented the Postman desktop app from booting properly on Windows machines.

What’s New

Test and debug webhooks in Postman

Available on Solo, Team, and Enterprise plans

• Generate a public HTTPS URL to register with any webhook provider - Stripe, GitHub, Slack, Linear, and others.

• Inspect full request payloads and headers in real time, with shared visibility for your whole team.

• Forward incoming requests to a localhost server or any URL.

• Replay any captured request with one click.

• Configure dynamic responses to handle provider handshakes such as Slack URL verification.

To learn more, see Webhooks in Postman.

What’s New

Automate SDK updates with Postman and GitHub

Available on Enterprise plans

Postman can auto-generate client SDKs from a collection or spec and publish them to a linked GitHub repo. You can configure package distribution via package managers like npm for TypeScript SDKs. Changes to the collection or specification, like adding or removing requests, trigger a new SDK build and open a pull request with updated code. If you’re on a Team plan, you can still connect your SDK with GitHub and update it manually, but automated updates require an Enterprise plan.

To learn more, see Automate SDK updates with Postman and GitHub.

What's New

Validate API dependencies from your Playwright tests

Available on Solo, Team, and Enterprise plans

You can now use the Application Inventory to track the applications you build, the external APIs they depend on, and the test coverage validating those dependencies. The Application Inventory integrates with your existing Playwright test suite to automatically capture API interactions and validate them against your Postman Collections. This catches issues UI assertions alone miss, like contract drift, silent backend errors, and missing or incorrect API calls.

To learn more, see Application Inventory overview.

Improvements

Tag changelog entries with versions

You can now add version tags to your changelog to label and organize updates to your API specification. Tag the latest set of changes to group them under a specific version, view those changes in read-only mode, and share a direct link with your team.

To learn more, see Add a version tag to the changelog.

Bug Fixes

Fixed a regression introduced in app v12.7.6 where Evaluate, If, and Condition blocks stopped working in the Postman desktop and web app. Cloud-based flow runs were not affected.

Fixed an issue where Evaluate blocks would not execute with a ‘Result is undefined’ error message.

Fixed an issue in the HTTP Request block where input variables were being stripped when a path parameter used colon syntax (:resourceId) with a {{resourceId}} value, causing broken variable injection in flows.

What’s New

Introducing new SDK Generator languages: Kotlin, Ruby, and Rust

Available on Team and Enterprise plans

The Postman SDK Generator now supports three additional languages: Kotlin, Ruby, and Rust. Combined with existing support for TypeScript, Java, Python, C#, Go, PHP, and CLIs, you can now generate SDKs for your APIs in ten languages.

To learn more, see Generate SDKs in Postman.

Share API health with published monitor reports

Available on Solo, Team, and Enterprise plans

You can now publish read-only monitor reports that provide visibility into your API's uptime, performance, and recent run results. Anyone with the link can view the report in a browser without needing a Postman account or workspace access. This makes it easy to communicate API reliability to external stakeholders.

Published monitor reports show the last 30 monitor runs. Reports include the overall health status, success rate, and request-level details such as response times, status codes, and the number of test assertion failures. Monitor Editors can publish reports for monitors they have access to. On Enterprise plans, a Team Admin must approve requests to publish. Each monitor can have one published report at a time.

To learn more, see Share API health using monitor reports in Postman.

What’s New

Connect Flows deployed as MCP Servers

The AI Agent Block now supports MCP servers as tools, meaning you can connect any Flow deployed as an MCP server and let the agent call it during execution. This brings composable, reusable logic into your AI workflows: instead of rebuilding capabilities inside a single Flow, you can expose them as MCP servers and let the agent decide when and how to use them.

To learn more, see The AI Agent block.

MCP Trigger Block

Postman Flows now supports MCP (Model Context Protocol) as a trigger type. Create and deploy Flows as MCP servers to use them as tools in other AI applications and Flows. Generate tool definitions with AI or define custom schemas manually.

To learn more, see Create a deployable flow with an MCP block.

What’s New

Visualize test assertion failures under load

Postman now supports the Tests vs VU view in performance test results, giving you a clear view of how your test assertions behave as load increases. This view includes a heatmap that highlights failure rates across virtual user levels, helping you quickly identify when and where your business logic starts to break under load.

To learn more, see View test assertions by virtual user load in performance tests.

Improvements

File watcher support in Postman Flows

When working in Native Git mode in Postman Flows, local file changes now automatically sync to the Postman app. This works whether you're editing in your IDE, terminal, or file explorer.

Folder support in Postman Flows

Create and organize Flows in folders locally. Folder structures automatically mirror in the app, and push/pull operations maintain your organization without dependency conflicts or rename issues.
