When creating forms in hubspot we used to be able to navigate to the options tab and select a Salesforce campagin so that we could push all the leads that downloaded that form into salesforce. That is no longer an option for us. Did Hubspot remove or move this functionality?
I’m not aware of it being removed. Are you using a custom forms module with your landing page or CMS page that is not showing this option? Also, if you are embeded the form yourself, you could customize the embed code and add in a value for “sfdcCampaignId”. https://legacydocs.hubspot.com/docs/methods/forms/forms_overview
