Knockout01 / Stored
Ready to repeat.
Save a password with an entry for convenient testing. Stored passwords are unencrypted in your local Chrome profile.
Knockout / Punchout test helper
One setup.
A round trip.
From supplier login to returned cart. Test your punchout integration and see exactly what comes back, right in Chrome.
Chrome Web Store release in preparation

A place for every
supplier setup.
Create reusable entries, choose the setup endpoint, and fill in the fields. Save when you want to keep a setup. Execute when you want to test, even before saving.
The response,
without the guesswork.
Inspect returned form fields and readable XML. Download JSON or the original XML for further investigation. Keep useful sessions and delete individual results when you are done.
Choose how you work
Three ways to supply a password.
02 / Ask on execute
Enter it each time.
Supply a password when you start a session. It is used for that request without being saved in the entry.
03 / 1Password
Keep it in your vault.
Save a secret reference and retrieve the password on Execute. Requires the optional helper and 1Password desktop app on macOS Apple Silicon.
Your data.
Your chosen supplier.
Execute sends your credentials and setup fields to the supplier you select. Entries and captured results stay in your Chrome profile until you delete them. Knockout has no analytics or publisher-operated collection server.
Site access is requested as needed. If the supplier redirects to another storefront, approve that site before checkout.
Read the privacy policy →Before your first round trip.
What do I need?
Chrome 119 or newer, an installed copy of Knockout, and an authorized supplier test endpoint with credentials. Remote setup endpoints must use HTTPS. The extension's local test mode accepts localhost or 127.0.0.1 with dummy data.
Do I need a local callback server?
No. Knockout captures the checkout postback for an active test session. It uses a fixed HTTPS localhost callback on port 13371; the fallback network observer may attempt a connection to that address.
Does 1Password need to be installed?
Only if you choose the 1Password password mode. Stored and Ask on execute work without the native helper.
Where can I get help?
Read the setup guide or email chrome-dev@mju.se. Remove credentials and private supplier data before sharing screenshots or payloads.
