Hubspot Integration- Trapping Leads

I am trying to have leads from a short form in Unbounce integrate with Hubspot. However, the leads will not integrate. I’ve followed the steps of integration, but still no progress. I’ve created a form in HubSpot to match the form fields on the Unbounce landing page. I’ve also mapped the fields. Has anyone else had this problem or know a solution? Would is be easier to just embed a HS form into the Unbounce landing page?
