Hi Jep, This is a great article, learned quickly to set this up. I've manged to POST successfully with Email, formid, munchkinId.
What I'm not understanding is the '_mkt_trk'. above in the article you state "if you have Munchkin on your form page" does this mean to place my marketo form onto a marketo landing page for the Munchkin to work? I thought by your article that I dont need a landing page just a blank form to POST to.
Also, "If no, read it from the cookie with the same name and pass it to Marketo in this field" How do I set up to read it from the cookie?
Since this method has become quite a bit more popular, I just wanted to add a little extra information to the method that Jep provided. There are three required parameters in the POST made to the Marketo Leadcapture URL. These are case sensitive: 'formid' the ID of the form you want to appear in the activity log, 'returnLPId' should equal -1, and 'munchkinId' which is your Munchkin ID.
We've been successfully using this method to post leads into Marketo for about 1 year and we noticed over the last couple of weeks, that we've been receiving a HTTP 429 response ( Too Many Requests) after ~10 consecutive form posts from some of our external vendors. Has something changed that would cause the server to timeout after multiple requests? Maybe something in a recent release? If there's a new timeout limit, how much time should we wait between posts? Thanks, Brian.
