Build an Online Store

Not an entire online store, just a portion of the checkout process for a few of our items that require samples to be sent to a separate company via mail. The process will yield a unique code, which the customer is to record and confirm that they have recorded. Then it will send the unique code to the separate company without storing the code on our servers, or sending the code to the customer via email. We\'re currently using wordpress / bigcommerce.\r\n\r\nOrder flow\r\n\r\n1. Customer arrives at confirmation page after purchase\r\n2. Unique code(s) are generated\r\n3. Customer must check the \"I agree\" box before the \"Submit\" button can be clicked\r\n4. Once \"I agree\" is checked and \"Submit\" button is pressed, A box below will begin going through the following steps:\r\n\r\na. Verify payment was processed. \r\nb. Email the code, and only the code (no order or customer information) to \"Secure Lab Server\" (email account for separate company to retrieve code)\r\nc. Login and check \"Secure Lab Server\" email account to verify email was sent.\r\nd. Verify order saved properly.\r\ne. Email order confirmation to customer. Do not email code.\r\nf. Display order complete message.\r\ng. Stay on this screen\r\n\r\nWe must ensure that no logs are kept anywhere on our servers that record the unique code(s.) It will be emailed to the \"Secure Lab Server\" email account, but we (as the order processor) will not possess the code in any way once it is generated and the customer clicks \"I agree\" and \"Submit.\"
