Hi, sorry for bothering, I'm new to hubspot, I've searched in this forum, but I have not found the solution. I currently have a landing page (html / php) and I need to be able to send the form information directly to hubspot in order to manage them as prospects.
As @Mike_Eastwood said, the easiest way to implement a HubSpot form on your site is to embed it.
If you have already built a custom form, however, you can connect it to HubSpot with the v3 Forms API. To do this, you must first create a mirror of your form in HubSpot to receive the submissions.
