Co-Branded User Interface (CBUI)

A customer who is ready to buy a product clicks a Buy Now button powered by Amazon FPS to authorize a payment. The button redirects the buyer from your web site to the Co-Branded User Interface (CBUI). You cannot issue an Amazon FPS Pay request until a buyer has successfully completed the CBUI web pages, and has authorized the purchase.

The CBUI is a series of web pages, as shown in the following figure.

For buyers, the CBUI is a series of web pages they use to authorize the payment. The CBUI web pages ask buyers to sign in, to specify a personal payment instrument, such as a credit card, and then to authorize the purchase. Anyone who has purchased something on Amazon.com is familiar with the final approval in the checkout process where you commit to spending your money.

For the merchant, the CBUI is a series of web pages in which the merchant registers with a caller for a marketplace storefront on the caller's web site. Merchant registration is only required in marketplace selling environments. You use the recipient token ID returned from that request to pay merchants in the purchase transaction.

The CBUI enables you to include your company's branding on the CBUI payment authorization web pages. This makes for a better buying experience. Clicking a Buy Now button powered by Amazon FPS redirects the buyer away from your web site to Amazon's. By including your branding on Amazon's CBUI web pages, buyers don't feel as if they've left the your web site to authorize a payment. The CBUI provides continuity between the checkout and payment authorization experience.

For merchant registration, co-branding provides a similar, improved customer experience.
