Test key

Each widget has a test key, pk_test_…, beside its live key. It is a dry run on the rental's real cars and prices. You try the whole widget, Pay and the done page included, and nothing lands on the rental: no car is held, no booking is made and no money moves.

Where to find it

In Mellow, open Settings · Widget and the widget. The Test card below Install holds the code with the test key, and Copy code copies it. Rotate test key in the page's Show more makes a new one: the old test key stops at once, and the live key does not change.

Where it works

• Your own machine. The test key passes from http://localhost, http://127.0.0.1 and http://[::1], on any port, http or https. The live key never does.
• Your sites. The test key also passes from the widget's own sites, so you can try a page on the real site before you change to the live key.

What it does

• The reads give the live answers: the same locations, car types, products, availability and prices.
• Pay runs every check of a real hold, the bot check included, and prices it the same, with the same refusals, such as none_free. Then it keeps no car.
• The payment goes to the processor's sandbox. When the processor's sandbox is not set up in Mellow, Pay shows Open test payment, which opens Mellow's own test page in a new tab, with Pay and Refuse card. The widget moves to done by itself once you pay there.
• The done step shows "Test booking TEST-4F2A", with no links to manage the booking or to check in. mellow-booked gives reference 0.
• The bot check runs with Cloudflare's test sitekey, which always passes.
• A test key may call only the reads, the holds and their payments, the widget's settings and the currencies. Any other route answers 403 forbidden.

Change to the live key

1. Add the site to the widget's Sites in Mellow, as https://www.example.com.
2. Change auth="pk_test_…" to auth="pk_live_…". The rental stays the same.
