  ## Bookmarking Offerings [/api/v2/store/{store_name}/description/{description_name}/offering/{offering_name}/bookmark]
  
  Users can bookmark offerings so they can access their favourite ones in a very easy way. This endpoint can be used to both
  bookmark and unbookmark a specific offering depending on its previous state: if the offering is already bookmarked, it will be 
  unbookmarked; if the offerings is not bookmarked, it will be bookmarked.
