Postman App Release Notes

What’s New

Invite Partners using invite links

You can now invite partners to partner workspaces using invite links. To learn more, see Invite collaborators to a Partner Workspace.

Improvements

Two-way synchronization support for collections and Spec Hub

Postman now supports a two-way synchronization between OpenAPI 3.0 specifications and collections. Whether you generate a collection from an OpenAPI 3.0 specification or a OpenAPI 3.0 specification from a collection, you can now make changes to either, then sync your changes to the other.

Improvements

Scheduled actions in Flows

• You can now run Flows actions automatically at custom intervals. With scheduled flows, you can set up recurring workflows directly on the Flows canvas and keep your automations running right on time.
• Schedule actions using natural language ("Run every day at 9 AM")
• Deploy scheduled workflows that trigger automatically
• Scheduled runs appear in analytics
• Try it out by adding a Schedule trigger to your next action in Flows, and watch it run automatically. To learn more, see Schedule an action to run automatically.

Postman Flows - Flow events in workspace activity

• Flow activities like creating, deploying, and taking snapshots of actions and modules now appear in your workspace activity feed, making it easier to track changes and collaborate with your team.

Postman Flows - New default AI model

• The default AI model for AI Agent blocks in flows has changed from GPT-4.1 to GPT-5.

Postman Flows - Easy navigation to module file from the AI Agent block

• You can now navigate directly to a module from the tool list in AI Agent blocks, making it easier to review and edit module configurations.

Bug Fixes

• Fixed an issue where user suggestions in the workspace invite modal were intermittently missing for very large teams.

Improvements

Run saved requests in scripts across workspaces

The pm.execution.runRequest method now supports sending requests in other workspaces. This method enables you to send requests stored in an HTTP collection from another request’s pre-request and post-response scripts, making it easier to reuse requests. With support across all workspace types, you can now build more powerful workflows that extend beyond a single workspace.

To learn more, see Use scripts to send requests stored in your collections.

What’s New

Run saved requests in scripts You can now send requests stored in HTTP collections from another request’s pre-request and post-response scripts, enabling you to easily reuse requests. Use the pm.execution.runRequest method to reference a request using its ID. The referenced request runs as it’s configured in its collection, including its parameters, variables, and test scripts. You can also use an options object as an argument to override variables used in the referenced request. To learn more, see Use scripts to send requests stored in your collections.

Improvements

Keyboard navigation in Collection Runner reports Quickly scroll and page through Collection Runner results using the arrow keys and keyboard shortcuts. This small tweak adds up when you’re skimming hundreds of requests. To learn more, see Troubleshoot large collection runs.

Improvements

Types enabled by default in collections

Types are now enabled by default in all collections, making it easier to design and test APIs with the Postman Collection format. Define types, such as data type and possible values, for your request parameters, headers, and body data. Types help your consumers understand your API and send valid requests. Postman also validates your requests using types you defined and identifies possible issues. To learn more, see Design your APIs with Postman Collections.

Minimum and maximum types in a collection only accept a range

Values for minimum and maximum types in a collection can now only be a range. Postman doesn’t allow you to enter values not in a range, such as a minimum value of 9 and maximum value of 5. To learn more, see Add types to parameters and headers with an API collection.

Enum types in a collection support entering a list

When adding possible enum types in a collection, you can now paste a comma-separated list, such as "red,green,blue". Postman adds each value in the list as its own possible value, enabling you to quickly add a large list of values. To learn more, see Add types to parameters and headers with an API collection.

Key-value shortcuts support types for parameters and headers

Postman now retains type information for each parameter or header row when you copy and paste, duplicate, or move a row. Learn about Postman shortcuts.

Note: Types are only available in the US region.

Bug fixes

• Fixed a bug where the Visualizer wasn’t working.
• Fixed a bug where the CSV file preview for Collection Runner wasn’t working.

What’s New

Introducing sampling support for MCP requests

Test and troubleshoot your MCP server's sampling capability. Sampling is when the server prompts an AI model to complete a task it can't complete itself. For example, if a server can access your calendar, but can't summarize your weekly schedule, it can prompt an AI model to summarize it for you. With Postman, you can use an intuitive UI to respond to such a request and see how your server behaves in real time. To learn more, see Use your MCP request to interact with an MCP server.

Introducing support for adding MCP servers

You can add an MCP server to Postman Agent Mode to give it further context and extend its capabilities. You can also export an MCP server configuration to set up an MCP host, such as Claude Desktop, VS Code, or Cursor. Once you set up your app, its AI models or agents can use the MCP server for the same added context and capabilities. To learn more, see Add an MCP server to your MCP host.
