Hosted Payment Pages are no longer available
This page is for the classic Hosted Payment Pages (HPP) integration, which has reached end-of-life. We are no longer processing transactions though HPP.
If you have any questions, contact our Support Team.
Level 2 or Level 3 (L2/L3) data provides commercial shoppers with additional information about purchases on their card statements. It allows companies to track how much is spent on their corporate cards where a single card may have multiple users.
Companies can also track the amount of sales tax to pay or reconcile transactions using a unique customer code. Transactions submitted with L2/L3 data that meet requirements have lower interchange rates.
Code example
Below is a code example for submitting L2/L3 data in an authorisation using the Adyen Hosted Payment Pages (HPP):
