What Postman Interceptor does
Postman Interceptor is a browser extension associated with Postman. The official material describes it as: “Capture requests from any website and send them to Postman Client.” This guide uses the recorded store pages and official project material to explain installation, first use, documented functions, browser coverage, pricing signals, permissions, privacy checks and troubleshooting without treating promotional claims as independently tested results.
Postman Interceptor has verified store entries for Chrome, Microsoft Edge, Firefox. Use the browser icons on this page to reach those exact listings because similarly named extensions can belong to different publishers. The Chrome entry is the primary catalog reference for this batch; Edge and Firefox are included only where the corresponding product was matched and checked.
Postman Interceptor acts as a browser companion to the Postman desktop app.
Interceptor enables you to capture network requests and cookies directly from Edge.
Once Interceptor is running, you can start a debug session, which is a time-bound session of traffic capture.
You can start, pause, and stop an interceptor debug session, then later start another one.
How to install Postman Interceptor
Open the official store icon for the browser you currently use: in Chrome select Add to Chrome; in Microsoft Edge select Get; in Firefox select Add to Firefox. Confirm that the title is Postman Interceptor, compare the product icon and publisher with this page, and read the permission dialog before accepting the installation. This helps avoid a different extension with a similar name.
After installation, open the browser Extensions menu and confirm that Postman Interceptor is enabled. Pin its toolbar icon when the product uses a popup; if it changes a new-tab page or adds controls inside supported websites, open a fresh tab or reload the target page. Start on a non-sensitive page until you understand the interface and access it requests.
Use only the verified Chrome, Microsoft Edge, Firefox store links shown on this page.
Confirm the listed publisher: Postman.
Review optional site access before enabling it for every website.
First-use workflow for Postman Interceptor
Postman Interceptor acts as a browser companion to the Postman desktop app. Begin with the narrow task described in that official material. Open the toolbar popup, replacement page or supported website that the extension provides, complete one representative action, and compare the result with the original browser workflow before making it part of daily work.
Interceptor enables you to capture network requests and cookies directly from Edge. Controls can move between versions, so use the current interface and official help links as the final reference. If an account, API key, local companion app or website permission is requested, complete only the setup required by the specific feature you intend to use.

Documented features and practical controls
Once Interceptor is running, you can start a debug session, which is a time-bound session of traffic capture. The screenshots on this page come from an official browser store or the official project repository and show the interface or functions available when they were captured. A screenshot is useful for orientation but may not match a later release pixel for pixel.
Use the extension settings to review behavior that can be changed, disabled or limited by site when those controls are available. Test one change at a time, reload the affected page, and keep the original data or browser state when the tool edits, downloads, filters, converts, synchronizes or submits information.

Who Postman Interceptor is for and how to evaluate it
Postman Interceptor is most useful when the documented function removes a repeated browser step or exposes information that would otherwise require a separate page. Evaluate it with a real but low-risk task: record how many steps the normal workflow takes, repeat the same task with the extension, and keep it only when the benefit is clear enough to justify another browser permission and background component.
For security, finance, AI, translation, downloads, account management or content-processing tools, independently verify important output and destination details. An extension can shorten a workflow, but it does not replace backups, the original website, professional advice or review of a transaction before confirmation.
Test one representative task before enabling broad site access.
Verify generated, translated, filtered or financial output independently.
Remove the extension if its current behavior no longer matches the documented purpose.
Free use, paid features and account requirements
The captured official material does not present a required purchase for the core browser extension, so this directory records Postman Interceptor as free to install. That label is not a promise that every connected account, network transaction, optional service, donation feature or future release is free. Confirm current terms on the official product page before relying on the extension for a paid workflow.
Account requirements can differ by feature and browser. A local utility may work immediately, while synchronization, cloud processing, AI models, support, team functions or connected services may require sign-in or separate terms. Read the current checkout and account screens instead of relying on an old review, because plans and regional availability can change after this research date.
Check whether the exact feature you need requires an account.
Confirm current limits and regional prices on the developer website.
Review renewal and cancellation terms before starting a trial.
Permissions, privacy and current version
The captured product data reports Edge 3.2.1; Firefox 3.2.1. Where an Edge manifest was available, it declared or requested items including: webRequest, nativeMessaging, storage, cookies, scripting, tabs, *://*/**. A permission list describes technical access, not proof of how the publisher uses data. Read the browser prompt, restrict optional site access to the pages that need it, and review the current privacy information before entering confidential, financial or personal content.
No official source repository was required for this entry; the factual description comes from the captured official browser-store material. Store versions can change independently across Chrome, Edge and Firefox. Check the update date, release notes and ownership shown by the store before enabling an old installation again, especially when a workflow handles credentials, cookies, page content, downloads or account data.
Recorded versions: Edge 3.2.1; Firefox 3.2.1.
Manifest generation: 3.
The captured Edge listing includes a publisher privacy-policy link.
