I use "API Request" tool. To set header dynamically, I added another property with same name. Anyway, it works. But is this genuine way ? For example: I need to send different "Authorization" Header value for each Assistant. For this, I set "Authorization" property in properties list. If I don't set this property, header does not get variable. Here also goes snapshot of system prompt. * For all tools prefixed with

hubspot_

, set the

Authorization

parameter as "Bearer {{API_key}}" https://cdn.discordapp.com/attachments/1211484481848873020/1392970540825841674/img_202507101.png?ex=68717869&is=687026e9&hm=d90da54e2907f08f59f86c8bfd3b780fd32eba1c7c80f5868c531d96c09235bc&
