Each funnel's merchant and product paths

You switch a checkout to a new merchant with a page event rule, then wonder whether the upsell after it still charges through the old one. The only way to find out used to be a test order on a live card.
The enemy is a funnel path you can only check by buying from it.
Which funnel runs? on the Funnels list already told you which funnel a URL resolves to and why. It now also shows what happens on that page. The Merchant row names the merchant the URL charges through, with its gateway, and says when a page event rule picked it. If the page's events or backend script send a visitor to that URL somewhere else, a warning names the address they land on.
After a purchase lists every product on the page and the page the buyer lands on next. Products that lead to the same page share one line, so a page with six buy buttons and two destinations reads as two lines. On an upsell, No thanks shows where a decline goes. A split test or a condition is named with its number of arms, a draft page is marked as a draft, and a product with no next step says the buyer gets the merchant's or the default thank-you page.
The test runs the page's backend script, page events and funnel nodes as a visit would, in a dry run. Tracking is switched off and split tests are read without being counted, so the test adds nothing to your numbers.
Try it: open Funnels, click Which funnel runs?, paste a page URL from one of your domains and click Run test.
