adyen-node-api-library VS mollie-api-node

The first step is to install the Adyen API library, these examples will be in TypeScript so we’re going to use the Node.js library. These examples are built using version 15.1.0 of the api-library which utilizes the latest version of Checkout API (71).

Next, we need to iterate over the list of notification request items, and process them based on the type of event the notification item is associated with (i.e., its eventCode). As we iterate through the list, however, we’ll also want to verify its HMAC (hash-based message authentication code) signatures. This helps protect the application server from unauthorised notifications, such as any data that may have been modified during transmission. Since our application leverages the Adyen Node.js server-side library to interact with Adyen’s API, we can conveniently import and instantiate the built-in HMAC validator class to do just that:

Im not currently using it, but i had great experiences with mollie (https://www.mollie.com/).

It can make sense to think more modular when it comes to ecommerce, based on what you need. Shopify is an all integrated solution, like Apple is for computers. But there are also companies that cover a part of an ecommerce stack with their APIs, like Mollie. They cover many different payment providers and a checkout flow, similar to Shopify but integrated into your own site. They have a Node API.
