If you are using the optile's Hosted Payment Page and you would like to present your customers the interactions codes of a transaction, especially in the reason for denial for a failed transaction, then this will be automatically displayed. However, there are some limitations to this feature, for example:
1. If there is any redirect payment method or any 3D Secure process involved in the transaction, then no interaction codes or reasons will be displayed on the payment page.
2. If you are using Native integrations then you would have to build up and display the message yourself.
3. At the moment, the interaction reasons are available only in English and German. If other languages are required for the Hosted Payment Page integration, please let us know.
Here you can find the different lists of interaction codes and reason.
For any questions please do not hesitate to contact our support team.
