Update Marketo with Marketo no forms

Anonymous

We are using Marketo to do newsletter subscriptions.
For that we have developed a form and a thank you landing page in Marketo. These assets are embed in a page of our website.
Now we want to add more data to subscriptions database through other forms (not Marketo forms) that we have in our website. For example, every time someone register in a webinar, we want to collect more data (number employees, city, etc.) to the subscriber.
We thought to do the integration using Munchkin and also syncLead webservice. The problems is, this way we capture all the people who fill the form and not only from the subscribers.
We just want to capture data from subscribers.
Any suggestions of how is the best way to do this?
Best Regards,
Andreia

This sounds like a use case for a server-side post. This approach allows you to collect data using your own forms. You can then send the data you would like from your server to Marketo.

A hidden field such a checkbox could differentiate current subscribers from occasional visitors.

That field coould be pre-populated by an URL parameter.
