Overview

Back to top

KeyOne provides decentralized data and identity management solutions that empower users with lightning-fast checkout and therefore a very good checkout experience.

The KeyOne Fast Checkout extension for Magento is designed to streamline the checkout experience for their customers. With a single button click, users can quickly fill in their details, making the checkout process faster and more user-friendly. In addition, the addresses of the users are thoroughly validated, which reduces incorrect order placements. This plugin is ideal for stores looking to enhance user experience and reduce cart abandonment.

Account & Pricing:

A separate KeyOne business account is needed to use this plugin. The business account essentially provides API credentials to use this extension. An automatic account won't be created upon plugin installation. The account is free to create, just like the checkout functionality, but should be obtained by contacting info@keyone.me. 

Features:

Fast checkout solution

  • Adds a “KeyOne Fast Checkout” button on the checkout page.
  • Auto-fills user information for a seamless checkout experience.
  • Provides a hassle-free checkout experience to the customer, which reduces cart abandonment.

Reduce return rate

  • Users' addresses are thoroughly validated before they are stored in KeyOne which are then transmitted  during checkout.
  • This validation reduces the return rate because of incorrect customer addresses.

Lightweight and easy to configure

External Services

This plugin connects to KeyOne’s external API to fetch user details for checkout autofill functionality. This inclusion helps customers to quickly complete the checkout process.

  • Service Used: KeyOne Checkout API
  • Purpose: Automatically fill in billing and shipping details at checkout
  • Data Sent: The current website’s origin (URL) and Authentication tokens (JWT)
  • Data Received:
    – User checkout data from KeyOne account (billing/shipping address and personal details)

When is Data Sent?
– When a customer clicks the “KeyOne Fast Checkout” button, a new browser window opens and a request is made to https://checkout.keyone.me/shop-login with the website origin.
– Later, when user enters their login details, they are transmitted to the KeyOne login API.
– A JWT token is generated and sent to authenticate the future requests and checkout information is sent in subsequent requests.
