Attach File to HubSpot Deal via Task — Show in Attachments Section

I’m building an integration and need to attach a file to a specific Deal record in the CRM. The file should be linked through a Task, and it should appear in the “Attachments” section in the Deal’s UI.

  • Upload a file via API
  • Create a Task associated with the Deal
  • Link the uploaded file to the Task
  • Ensure the file appears under the Attachments
