Today we have changed some of the previously announced backwards incompatible changes. All of them are related to extended brand field – formerly only the brand name was provided, now endpoints use an object containing both code and name of a brand. In particular:
data.brandExt object.data.brandExt and we also removed parameter ?brand (which had been replaced by brandName last year).data.couponsTemplates[].brands from a string to an object. Now both brands and brandExt are equivalent. We will remove the brandExt on April, 13th, 2021.
