Authorize.net Relay URL Whitelisting For WooCommerce
What is Relay Response & why it is important?
Relay Response is applicable to merchants using Server Integration Method (SIM), Direct Post Method (DPM) and Simple Checkout. It instructs the payment gateway to return transaction results to the merchant using an HTTP POST to a specified URL on the merchant’s Web server. A script or program at the URL can be used to create a custom receipt page using the transaction information. The custom receipt page is then relayed back to the customer’s browser. Relay Response is important to send transaction response back to your woocommerce site, so it knows transaction status.
