Amazon Simple Pay for WooCommerce sends your customers to Amazon’s secure payment website to enter their payment information. Customers can use their credit card or Amazon Payments balance to pay for their order. You’re just moments away from getting the gateway setup and accepting payments!
You must have an Amazon AWS account, and the Simple Pay feature 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.

There are two filters available to customize the transaction information that is sent to Amazon:
  • apply_filters( 'wc_amazon_simple_pay_button_parameters', $this->parameters, $order ) which passes in the button 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.
