Amex Express Checkout

Christian Anderson on August 18, 2015

Starting today, you can add Amex Express Checkout to your site or app with a single code snippet.

American Express has partnered with Stripe to let over 20 million cardholders pay online and in apps using their existing American Express login, rather than entering their full credit card details.

When you integrate, American Express will also securely pass on useful customer information to you such as address, email, and phone number. They'll even automatically keep that info up to date. (You’ll get a customer.updated webhook.) You’ll have the latest information for your customers without having to prompt them to manually update their data on your site.

During our beta, we worked to make accepting Amex Express Checkout as straightforward as possible. To include the button, just configure the helper library with a client_id that you can generate in the Dashboard:

<amex:init client_id="30e73189-96f4-4797-83d4-6730bf6bed19"
  env="production" callback="aecCallbackHandler" />
<script src="https://icm.aexp-static.com/Internet/IMDC/US_en/
  RegisteredCard/AmexExpressCheckout/js/
  AmexExpressCheckout.js"></script>

As with other payment types, you’ll get a card token that you can use to create charges. You’ll also see these payments alongside other payment types in the Dashboard or via the API.
