So I'm in need to check to see if an attribute group contains a specific attribute_id. However using the API, there doesn't appear to be a specific endpoint which lists all attributes associated to a group, only to an attribute set.
What I was hoping to achieve was to use the endpoint:
searchCriteria[filterGroups] to search for a group_id field which doesn't appear to exist.
Does anyone know if this is even possible to do?
