The redeemable description is what is visible by the Guest within the app that gives a description of the specifics in regards to the redeemable the Guest has received.
In the description text visible within a redeemable you may want to use HTML to customize the description. Currently, within the redeemable description in the Punchh Platform, the ability to use HTML is not available.
Your CSM will need to submit Product Feedback to our development team to inquire if this feature can be added to the Platform in the future.
