What is Amazon Pay and Why Does it Matter? The Complete Technical Guide

Amazon Pay brings Amazon‘s familiar digital wallet and one-click checkout beyond Amazon.com. But how exactly does this technology work? What are the integration points and developer tools to support it?

This comprehensive guide dives deeper into the technical workings of Amazon Pay from an industry insider‘s perspective. We‘ll uncover usage stats, fees and pricing models, security practices, and overall positioning in the global payments landscape now and in the future.

Overview of Amazon Pay

Let‘s briefly recap what we know about Amazon Pay:

• Online and mobile payment service allowing consumers to use their Amazon account payment methods on third-party websites, apps, Alexa/voice services and in some physical stores
• For merchants, enables tapping into Amazon‘s embedded base of buyers and speedier, more trusted checkout flow

From a bird‘s eye view, Amazon Pay sits at the intersection between digital wallets, alternative payment platforms, and checkout optimization solutions.

As one of the world‘s largest e-commerce platforms, Amazon has the benefit of scale and continuous innovation. Based on current 20-30% annualized increases in usage, expect Amazon Pay‘s reach to expand significantly in the next 5 years.

Technical Integration and Developer Tools

The technical backend enabling Amazon Pay is quite complex. Let‘s explore some of the integration points and developer tools:

APIs and SDKs

Amazon Pay offers a robust set of application programming interfaces (APIs) and software development kits (SDKs) for incorporating it across platforms:

• Payments API – Primary API for transaction processing, authorizations, refunds, and account management.
• Login with Amazon API – Enables account verification and fast checkout.
• Alexa Payment API – Facilitates voice-initiated payments on Alexa devices.
• SDKs – Downloadable library modules for web, iOS, Android, Unity, .NET and Java developers.

These mature, full-featured developer tools make adding Amazon Pay straightforward yet customizable across various purchasing environments.

Tokens and Guest Checkout

Two advanced techniques supported by Amazon Pay‘s stack include:

• Tokenization – Enables merchants to only collect generic tokens instead of sensitive card data, improving compliance.
• Guest Checkout – Allows customers to pay without an Amazon account for more flexibility.

The guest option increases integration opportunities for retailers compared to mandatory account logins. And data tokens boost security.

Custom Payment Button

To initialize Amazon Pay, developers can easily generate and embed a Pay with Amazon custom button into their websites or apps:

<!-- Amazon Pay custom button code -->
<div id="AmazonPayButton"></div>
    <script>
      new OffAmazonPayments.Widgets.Button({
        sellerId: ‘SELLER_ID‘, 
        publicKeyId:  ‘PUBLIC_KEY_ID‘,  
        onSignIn: function(orderReference) {
          // Save orderRef and redirect as needed 
        },
        onError: function(error) {
         // Error handling 
        }
      }).bind("AmazonPayButton");  
    </script>

This renders a button tied to that seller‘s account credentials triggering the Amazon Pay workflow. Parameters like color, size and language can be configured.

While optional, personalized payment buttons matching a site‘s branding lead to higher conversion. They also offload PCI compliance to Amazon Pay.

For developers, Amazon Pay represents a payments platform investing heavily in tools accommodating varied technical needs – while keeping up with security best practices through techniques like tokenization.
