Bad request 404 - Missing required field

[Ljubica_KRUNIC]

Am using munchkin.marketo.net/munchkin.js to post lead information to marketo. But for some reason munchkin script is refusing to post the data with the following error:

Missing required field 'Email'

But as you can see we already have the email in the posted url below:

http://{{My-account}}.mktoresp.com/webevents/associateLead?_mchNc=xxxxx_mchKy=xxxxxx&_mchAtsalutation=Ms&_mchAtfirstName=ddd&_mchAtlastName=dd&_mchAtemail=my-address@domain.com&.......

Is there a way to debug such scenario? Thanks.

are you actually calling the munchkin function as per the docs?

Munchkin.munchkinFunction('associateLead', {
        'Email': 'my-address@domain.com',
        'FirstName': 'ddd',
        'LastName': 'dd'
    },
    'hashedkey'
);

Use the SOAP field names as per the docs - 'Email' not 'email'
