Connecting your Quriobot to Hubspot will, unfortunately, have to go via a intermediary party like Zapier, The reason for this is due to technical restrictions that Hubspot enforces on non-hubspot submissions.
So what you need to make this work is the following:
Step 1: Connect your QB to Zapier. This is described in detail on this page.
Step 2: Connect your followup step in Zapier to your Hubspot account. For this the Hubspot Create or Update Contact solution in Zapier was chosen.
-Use the Test This Step (in the Catch a Hook step) to get sample data which is then easy addable to the Edit Template section in the HubSpot connection in the second step.
