How to create an attachment for a ticket by using the API
I am converting a ticket entity from another system to HubSpot.
How can I create an attachment to a ticket by using the API?
Can I update the 'hs_file_upload' property by using this link or this is a read only property?
If this is not possible, should I associate the attachment to a contact and then associate the ticket to this contact?
Is there any other way?
