Hey @psjavi,

Files are associated to Contacts in the CRM using Engagements (Notes). When creating an engagement you can include the file ID by including it in the "hs_attachment_ids" attribute in your request. Once the engagement has been created you can then associate to the contact using to engagement using type "contact_to_note".
