If you collect a user’s email address when they complete the Authorize.net payment form, you can opt to send them receipt via email. To do this:
1. Navigate to the “Settings” section as described in the previous section.
2. Click on “Email Receipt” which is located in the “Transaction Format Settings” section.
3. Check “Email transaction receipt to customer (if email address is provided)”
4. Add any text that you would like to be sent to your users in the email receipt.
Note: If you want your users to receive an email confirmation receipt from Authorize.Net after they successfully pay through Authorize.net, you must collect their email address. To ask for an email address, customize the form fields to ask for “Email” in the “Customer Billing Information” section. Smith Cart automatically sends an email confirmation receipt so configuring Authorize.Net to send a receipt is not required.
