I'm using the api to Mailchimp and have been able to get data, but now need to put it. As part of the url I need to include the hash of the email address I'm updating in Mailchimp. One of the fields is Email Address, how do I get the hash (I assume md5) and use that in a variable in the url in the post back to Mailchimp.
I'm guessing I need to use javascript, but an example would help.
Thanks
