Payment keys are where a lot of WordPress store launches quietly go wrong. The beginner mistake is simple: people paste live credentials into a store they have not tested yet, or they leave test credentials in place after launch. This Hosted Payments guide walks through the clean path: create the test or sandbox keys first, put them into the WooCommerce payment plugin, run a safe test order, then switch to live credentials only when the checkout flow is confirmed.
