### API Announcement for March 4, 2021

##

On **April 30, 2021**, the Coupon API will limit the characters allowed in a coupon name.  An error will result if any special characters other than the following are used in the Coupon `code` field:

* Alphanumeric values

* White spaces

* Underscores ( \_ )

* Hyphens ( - )

To prevent a disruption in service, remove special characters from all coupon codes.
