Since the migration, there is no option to query items with “bonus_id” param. Is it something you’re planning to bring back ?
We were told over the Community Discord Server they are aware of this situation and they’ll discuss this internally. However there is no information on how or when this will be done.
I believe someone posted a workaround for this on the discord not long ago, I think it is worth checking it out.
Thanks for the answer and discord link that’s a really useful source of information, I will check it out !
