Collaborate in Postman
You can collaborate in Postman using the VS Code extension. You can share your collections, environments, and workspaces. You can also assign collection and environment roles to team members.
Share elements and manage access
You can share collections and environments directly with team members and groups. Team members with Admin access for the workspace or Editor access for the element can manage collection roles and environment roles assigned to team members.
When you share a collection or environment that's in a personal workspace, you can choose whether you want to move the element to a team workspace, or convert the personal workspace into a team workspace.
To share an element with a team member or group, do the following:
- Select a collection or environment you want to share, then select Share.
- Enter the name, email address, or group name for the people you want to share the element with.
- If you have the Editor role for the collection or environment you're sharing, you can give your new collaborators the Viewer or Editor role on the element. If you have the Viewer role for the element, you can share it, but you won't be able to assign roles.
- If you're sharing a collection, you can optionally select an environment to be the active environment. This will be the active environment for the team members and groups you want to share with. Select the Share with Environment dropdown list and choose the environment.
- Select Share.
You can also select Copy Link to copy the collection or environment's URL to the clipboard, and share the URL with team members.
To manage collection and environment roles assigned to team members, do the following:
- Select a collection or environment you want to manage roles for, then select Share.
- Select the role next to a team member or group's name, then select a different role. You can also select Remove to remove a team member or user group from the element.
Share workspaces
You can use the VS Code extension to invite team members and groups to collaborate in a workspace.
When you invite collaborators to a personal workspace, it's automatically converted into a team workspace.
- Select the invite to workspace icon to the right of the workspace dropdown menu.
- Enter the name, email address, or group name for the people you want to invite to the workspace.
- If you're a Workspace Admin, give your new collaborators the Admin, Editor, or Viewer role. Workspace Editors and Workspace Viewers can't assign workspace roles. Learn more about workspace roles.
- Select Send Invite.
You can also invite collaborators by selecting Copy Invite Link and sharing the link with them directly. Postman will prompt them to either sign in or sign up.
To learn more about sharing workspaces, see Postman's documentation.
Document APIs
Postman automatically generates basic documentation for any collection you create, including details about requests and sample code in various client languages.

To add a description to a collection or folder, do the following:
- Select the Collections tab, and then select a collection or folder.
- Enter a description in the Overview tab.
- Select outside of the editor to save your description.
To add a description to a request, do the following:
- Select the Collections tab, and then select a request.
- Select View Documentation in the top right.
- Enter a description in the right sidebar.
- Select outside of the editor to save your description.
To learn more about writing documentation, see Postman's documentation.
View documentation
You can view complete documentation for your collection that includes a description of each request and details such as the method and URL, the required authorization type, and any headers or parameters. For each request, you can view sample code in various client languages, and example response bodies and headers.
To view the complete documentation for a collection, do the following:
- Select the Collections tab, then select a collection.
- In the Overview tab under the Description, select View complete documentation. The VS Code extension will open the complete documentation in a new tab.
You can customize the appearance of the documentation by selecting a language to use for sample code.
Import data
You can import collections and environments that were exported from Postman. You can also import requests from a cURL command. Optionally, you can convert a Postman request to a cURL command, and import it using the cURL command.
Postman no longer supports the collection v1 format. You can convert your collection's format from v1 to v2 to import it using the VS Code extension.
To import data, do the following:
Select the import icon at the top of the sidebar.
Do one of the following:
- Select cURL, then enter your cURL command. The VS Code extension opens the request in a new tab. To import the request, save it to a collection.
- Select File, then select collection or environment files. If you're importing a single file, the VS Code extension imports it after you select it.
- Select Folder, then select a folder that has collection or environment files.
If you're importing multiple files or a folder, select the checkbox next to the files you want to import, then select Import.
Generate code snippets
You can convert an API request into a code snippet in the language of your choice. Available languages and frameworks include cURL, Node.js, Python, and more.
To generate a code snippet, open an HTTP request, then select Code (below Send). Select a language or framework from the dropdown list, then copy the code snippet to your clipboard.
Use cookies
You can view and edit cookies associated with different domains. You can then use the cookies stored in the cookie jar when sending HTTP requests in Postman.
To manage cookies in the VS Code extension, open an HTTP request, then select Cookies (below Send).
You can also open the cookie editor with the Postman: Open cookies editor
command in the Command Palette.
To learn more about using cookies, see Postman's documentation.
Test your API
You can use the VS Code extension to test an API's functionality. You can add test scripts to your collection, folders, and requests. You can also run a collection's or folder's requests in a specific sequence.
Test your API using scripts
You can add API test scripts to collections, folders, and requests that run after a response is received. Add tests to confirm that your API is working as expected, and help you debug your API if something goes wrong. Postman supports test scripts written in JavaScript.
To add test scripts to collections, folders, and requests, do the following:
Select a collection, folder, or request you'd like to add tests to.
To learn more about testing collections and folders, see Postman's documentation.
Select the Tests tab, and add your API test scripts. You can add your own test scripts and snippets of commonly-used test code. For test script examples, see Postman's documentation.
Optionally, you can add log statements to your test scripts to help you debug your requests. Logged statements display in the Postman Console.
Select Send to run your request. The tests will execute after a response is received. In the Response section, select the Test Results tab to review the results of your tests.
To learn more about writing tests scripts and using snippets of commonly-used test code, see Postman's documentation.
Test your API using the Collection Runner
You can use the Collection Runner to manually run a collection's or folder's requests in a specific sequence, enabling you to test an API's functionality or performance. You can also automate collection runs in your CI/CD with the Postman CLI or Newman.
By default, your requests run in the sequence they're listed in the collection. If you need to change the order of execution, select and drag a request to its new location in the sequence. You can also remove an individual request from the run by clearing the checkbox next to its name. You can optionally use API test scripts to pass data between requests and alter the request workflow. Learn how to customize a collection run with test scripts.
To manually run requests in a collection or folder, do the following:
Select a collection or folder with requests you want to run in sequence.
Select Run to configure the collection run.
If you want your collection to run with an environment, select it using the environment selector at the top right. You can also select Create New to create a new environment. Learn how to manage environments in the VS Code extension.
Choose any configuration options:
Iterations - The number of iterations for your collection run. You can also run collections multiple times with different data sets to build workflows.
Delay - An interval delay in milliseconds between each request.
Data - You can import a data file and use its values in the collection run. The data file must be in CSV or JSON format. Learn more about running collections using imported data.
Persist responses for a session - Log the response headers and bodies so you can review them after running the collection. For large collections, persisting responses may affect performance.
Request and response details are persisted locally during your current Postman session and aren't saved permanently. Signing out of Postman, signing into another device with the same account, or refreshing your browser will end your session and remove the logged data.
Response and request details are available for the person who started the collection run. Other team members can't view details for collection runs that you start.
Advanced settings
- Stop run if an error occurs - By default, the collection run stops if an exception is encountered within a script or if there's a problem sending a request. Clear this checkbox if you want the collection run to continue after an error occurs.
- Keep variable values - Persist the variables used in the run, so any variables updated by the run will remain changed after it completes. If you don't persist variables, changes aren't saved after the run completes. Note that persisting variables in the collection run will update the current value only.
- Run collection without using stored cookies - If your requests use cookies, you can optionally deactivate them for a collection run.
- Save cookies after collection run - Save the cookies used in this session to the cookie manager. Any values changed by requests during the run will remain after it completes.
To run the collection with your completed configuration, select Run (collection name).
Your Postman plan gives you a limited number of collection runs you can use each month. This limit applies to collections you run manually. A collection run with multiple iterations counts as a single run.
When running collections manually, Postman displays the results of your request executions and test results in real time. To learn more about what happened during the collection run, you can:
- Select a request to view more details about it, including the response, headers, and request.
- Select the name of a request to open it in a new tab.
- Select the Passed, Failed, or Skipped tabs to filter the results by test status. To show all requests, select the All Tests tab. If any tests in a request script fail during a collection run, the whole request fails.
- Select View all runs to view the run history for your collection.
- Select Run Again to run the collection again using the same settings.
- Select + New Run to configure a new run for the collection. Make changes to any settings, and then select Run (collection name) to run the collection again.
You can also view the run history for your collection, including collections you ran using the Collection Runner and the Postman CLI. Select a collection or folder, then select the Runs tab. You can filter your run history by the number of collection runs to view, users who ran the collection, the test status of the collection runs, and the source of the collection run. To return to the results of the collection run, hover over a collection run and select the view report icon.
Troubleshoot with the Postman Console
You can use the Postman Console to troubleshoot your requests. You can also use the Console to debug pre-request scripts and tests scripts, logging output to the Console. To open the Postman Console, select the console icon at the top of the sidebar.
