I need to integrate a website with our Marketo. It is using Drupal 6.x that currently has a form filled out, calls Hubspot via an API call to pass the lead information and then calls their license generation server.
We are looking for the Marketo equivalent to the Hubspot API call so we can move them from Hubspot to our Marketo.
I found this but I don't know if it is the best approach https://www.drupal.org/node/2190655.
Any recommendations from you Marketo gurus?
