The attached basic Windows program shows you how to add a Member to a MailChimp List. To use it you need the following:
1) A MailChimp account with at least one List. https://mailchimp.com/
2) An API key. In your Account under Extras, you will find info on creating an API key.
3) The ID number of your List. http://developer.mailchimp.com/docum...ilchimp-api-3/ The getting started doc is relatively short and easy to follow. After reading it, I used the playground to GET my List. The ID is in the JSON that's returned.
To create a new Member in your list, you need an MD5 hash of the lowercase value of the member's email address. Searching the forum, I found code contributed by Clive Richmond.
The code uses Basic Authorization, not oAuth. Read about it here: https://en.wikipedia.org/wiki/Basic_...authentication The Base64EncodeString function in my code was in the DAW doc.
Hopefully this will jump-start your use of this API.
ps: the List ID & API Key in the code are bogus, you will need your own to run the program successfully.
