Post Data from Form 2.0 to Marketo and Target Page

You can find ways to do this on the developer site:
http://developers.marketo.com/documentation/websites/forms-2-0/

Hi Justin,

That was the first place I referred my Dev team to review when they had asked this question.  However, they were not certain that the information found there would accomplish what we are looking to do.  Is there something on that page in particular that you think will be able to help us meet our requirements?

Dev has built a form that we have tested, but we ideally need this form to be a Marketo form so that Marketing has control over the form (in case changes are needed), Marketing can use this form in different places for various campaigns (Marketo pages and pages in our CMS), and to prevent needing to switch out forms again like we did switching to 2.0 (there are currently 100s of landing pages this is used on in Marketo).  

If the only option was for us to do this using a Marketo form, would it be possible?

You could send this data using the REST API. 

Hi Murtza,

Using the REST API, what calls would we need to use to post the data from the Marketo form to the target page and also bring the user to that target page upon submit?

@Val, using this approach you would pass form data to your server. Then use your server to send this data using Create/Update Lead REST API. 

Hi Murtza:
To be sure : the form that we will embed in our signup process will be custom built. We will submit the form and post the data directly to our target page and from there call in to Marketo using the rest API to handle lead related info.
This means that we will have to manually switch out the current Marketo singup form in 100s of landing pages with the new custom built form? I suspect this will be cumbersome to change manage. Is there a way to create and maintain it one place and then push it to all the landing pages without having it to do it 1 by 1 (sorry.. i am not very familiar with Marketo).
thanks!

You could also reverse the order in which you process the form data.  In other words, you could use standard Marketo form and then leverage a webhook that submits to your non-Marketo form.  A downside to this approach is that you would need to save all fields to Marketo.

Hi David:
So when the user presses the submit button, we capture it into marketo, then use the webhook to post data from my form (made availble as tokens?) to my target URL? 
When I looked at webhooks, it looked like you could cal an external APi and return the response back to the user.

In our case, the page I am posting to needs to be the page that the user  navigates to next.
Is this doable? if so, please tell me how.
much appreciated.
thanks!
