Emails to customers following payment

  Last updated: 


You can request email notifications be sent to customers following transactions on the Payment Pages. These are sent to the email address specified in the billingemail field. They are configured to be sent to customers following payment, summarising the transaction and acting as a receipt of payment for their records. By default, they look like this:



Configuring customer email notification

It is simple to enable email notifications on a transaction-by-transaction basis. For requests where you would like to receive customer email notifications, you will need to add the following fields to your POST to the Payment Pages:

<!--Sends email confirmation to the customer, following successful transaction:-->
<input type=hidden name="ruleidentifier" value="STR-2">

<!--Sends email confirmation to the customer, following declined transaction:-->
<input type=hidden name="ruleidentifier" value="STR-3">
  Any rule identifiers submitted (e.g. “STR-2”) need to be included in the string used to generate your request site security hash. Failure to do so will result in the customer being shown an “Invalid details” error message.


Included fields

The following fields are included as default within email notifications.

  If these fields are not populated during the payment session, they will be omitted from the email notification.

  • Auth Code
  • Billing Country
  • Billing County
  • Billing Email
