POST to another Marketo Instance

[Anonymous]

I am looking to submit form information to another marketo instance. I have the post url of the other marketo instance and the Munchkin id. I have added this in the webhook and added required fields I need to pass, but am returning a 404 error on the webhook. Is there anything I am missing?

Do I need to specify a form id on the third party end or should I specify the form ID of the form I am using?

You could use a tool like Firebug to inspect HTTP headers for a sample form post, and then do a diff to see what part of the request you are missing.
