Amazon FPS

This plugin has been retired, as Amazon no longer offers Amazon FPS payment processing services.


↑ Back to top
Amazon FPS (Flexible Payments Services) for WooCommerce sends your customers to Amazon’s secure payment website to enter their payment information. Customers can use their credit card, bank account or Amazon Payments balance to pay for their order. Amazon FPS includes full support for WooCommerce Subscriptions and Pre-Orders. You’re just moments away from getting the gateway setup and accepting payments!
You must have an Amazon AWS account, and the FPS product must be enabled for your account (add it here). This gateway does not require an SSL certificate. Not sure which Amazon gateway is right for you? Check out the Amazon Extension Comparison Guide.

Checkout Flow

↑ Back to top
After entering their information on the checkout page, the customer can select Amazon as a payment method: woocommerce-amazon-fps-checkout-experience After clicking “Place Order”, they are redirected to Amazon to sign into their account: woocommerce-amazon-fps-checkout-walkthrough-1 If they are shipping to a new address that is not listed in their Amazon account, they will be prompted to re-enter their payment information: woocommerce-amazon-fps-checkout-walkthrough-2 They can then choose the billing address associated with the payment method: woocommerce-amazon-fps-checkout-walkthrough-3 Finally, they will review and confirm their payment: woocommerce-amazon-fps-checkout-walkthrough-4 After clicking “Confirm”, the customer will be redirected back to the “Order Received” page on your store. At this point, their payment will be processed.

WooCommerce Subscriptions / Pre-Orders Usage

↑ Back to top
Amazon FPS is fully compatible with all features for the Subscriptions and Pre-Orders extensions. Because the recurring token provided by Amazon FPS limits your ability to change payment dates and amounts, the multi-use token is used to improve that flexibility. However, this results in a total lifetime billing amount being shown to customers when they are checking out: woocommerce-amazon-fps-payment-limits This is calculated based on the recurring total and length of the subscription. It is the maximum amount that may be billed to the customer during the lifetime of the authorization, it will never be charged all at once. After this limit is reached, the customer must renew the authorization by signing up for a new subscription. Most subscriptions should never reach this limit. For Pre-Orders, Amazon requires an expiration date for the payment token received. For your convenience, this is set to 6 months after the pre-ordered product is set to be released, so you may safely push your release date back a maximum of 6 months before the customer must cancel their pre-order and re-order.

IPN Issues

↑ Back to top
Amazon FPS relies on Instant Payment Notifications (IPN) sent from Amazon to your WooCommerce store to properly update the payment status for each order. Your store must receive these IPNs properly in order for orders to be processed correctly. Check the IPN status under WooCommerce > System Status to confirm that you can receive IPNs. If you continue to have issues with IPNs, please enabled debug mode to the log and submit a support request with the log file as an attachment.

For Developers

There are two filters available to customize the transaction information that is sent to Amazon:
  • apply_filters( 'wc_amazon_fps_cbui_pipeline_parameters', $this->parameters, $this->order ); which passes in the pipeline parameters and the WC_Order object. Use this filter to modify the payment description, add a co-branding logo, and more.
  • apply_filters( 'wc_amazon_fps_api_request_parameters', $this->parameters ); which passes in the request parameters. Use this filter to modify the charge description.
