How to submit data from one Marketo instance to another one?

We are having a hard time finding a way to send data from one Marketo instance to another Marketo instance. How would we send the data on form submit from one Marketo instance to another one?

We thought to use the form2.0 API, but couldn't find a way to send it since the current MktoForm2 variable is based on the account id, host url, and form id.

Scenario:

Marketo instance ABC is the destination.
Marketo instance 123 is what is loaded on the page using sample embed code below.
On form submit of form id testForm_123 (from 123 instance), it should send the data to ABC marketo instance.

What we tried that didn't work:

MktoForms2.loadForm("//app-123.marketo.com", "785-UHP-775", 1057, function(form) {
    form.onSuccess(function(values, followUpUrl) {
        var currentVals = form.vals();
        //send data to instance ABC
        MktoForms2.loadForm("//app-abc.marketo.com", "785-UHP-775", 1025, function(form) {
            form.vals({
                'email': currentVals.email,
                'phone': currentVals.phone,
            });

            form.submit();
        });
    });
});

Solution

Try the following with return false; to prevent redirection of outer form to allow for inner submit() to occur as well as a couple of semantic changes including using different names for the different forms within callbacks.

MktoForms2.loadForm("//app-123.marketo.com", "785-UHP-775", 1057, function(form123) {
    form123.onSuccess(function(values, followUpUrl) {
        var currentVals = form123.vals();
        //send data to instance ABC
        MktoForms2.loadForm("//app-abc.marketo.com", "785-UHP-775", 1025, function(formAbc) {
            formAbc.vals({
                'email': currentVals.email,
                'phone': currentVals.phone,
            });

            formAbc.submit();
        });

        // prevent redirection from happening of outer form
        return false;
    });
});

Hopefully that helps!
