@Michael_Soprano Yes. When the credit score is included in the profile, you can customize the offer to display the credit card interest rate by creating a decision rule. There are a few consideration, Interest rate information may come from various systems and relies on the data available in AEP to decide when to initiate the communication.
Check if you can break down the interest, credit card tier, and extra details into distinct schemas vs profile attributes.
