About Knockout

Test OCI, cXML and PEPPOL punchout sessions, from supplier login to the returned cart. Create reusable supplier setups, launch them in a new tab, and inspect the form fields and XML returned at checkout. Save an entry or execute it without saving. Download returned JSON or original XML, view readable XML previews, and delete individual sessions from history. Choose Stored, Ask on execute, or optional 1Password for passwords. Stored-mode passwords are saved unencrypted in your local Chrome profile. The included 1Password helper requires a separate installation on macOS Apple Silicon and a signed-in 1Password desktop app. Stored and Ask on execute do not require a helper. You need an authorized supplier test endpoint and credentials. Select the protocol, configure the endpoint and fields, then choose Execute. Allow the requested setup site and localhost callback access. If redirected to another storefront, approve that site before returning the cart. Remote setup endpoints require HTTPS. Knockout sends the credentials and setup fields you supply directly to your chosen supplier. Entries and returned cart data are stored locally until you delete them; they are not sent to the Knockout publisher. The extension reads active punchout tab URLs to request storefront access and captures the returned forms for those sessions. There are no ads or analytics. Site access is requested when needed. Knockout is an independent testing tool and is not affiliated with or endorsed by supplier platforms or 1Password.
