Hey HubSpot Experts

easiest way to do this is with a webhook from your checkout platform. when someone completes a purchase, have your site send a POST request to a HubSpot workflow webhook trigger with the buyer info (email, name, report purchased). the workflow can then create the contact if they dont exist and create a deal set to closed won automatically. if your checkout is on shopify or woocommerce theres native hubspot integrations that handle this without any code.
