title: Sending Salesforce web-to-lead form data programmatically
body: <p>Salesforce has a feature that gives you the ability to insert a web-to-lead form on your site. It's just a form with the action set to a servlet url, that the form posts the data to.</p>
  
  <p>I have an existing contact form on my site. I can't modify the form at all, but I can capture the submit event of the form and add custom functionality when the form is submitted.</p>
  
  <p>Is there an API method or some other way that I can programatically post the form data the same way as the Salesforce web-to-lead form does?</p>
