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.
