What is payload-payment-adyen?

This project is a payment connector that links Adyen, a payment processing company, to Payload Ecommerce, an online store platform. If you are building a shop with Payload Ecommerce and want to accept payments through Adyen instead of, or alongside, another provider like Stripe, this package handles the technical wiring for you. Once installed, the package sets up the parts a checkout needs: it talks to Adyen on the server to actually process payments, it provides the pieces needed to show Adyen's own payment form on the website, and it listens for messages Adyen sends back after a payment happens, such as confirming a charge went through, and checks that those messages are genuinely from Adyen using a shared secret key. It also includes admin only tools to capture a payment, issue a refund, or cancel a transaction. For people starting a brand new store with the standard Payload Ecommerce starter template, the package includes a command line tool that can automatically update the project's code to use Adyen. It can even remove the existing Stripe setup if the project has no past transactions that still need Stripe for things like refunds or record keeping, though the README recommends being cautious with that step on any project that already has real customer transaction history. Setting it up requires creating an account with Adyen and filling in several configuration values such as an API key, a merchant account name, and a security key used to verify webhook messages. The author describes the package as usable but still pre 1.0, meaning the way it works could still change as feedback comes in from the Payload Ecommerce community.
