I've scanned through the v3 API docs a number of times but the authentication flows don't really seem to fit my very simple use case. The docs reference a "redirect URI" and "granting access to an application", but in this case I am the user / application and I just want to insert an email into Constant Contact via API call. I have an email (received via form on my site) and I simply want to make a POST request to add this email to constant contact. I have my API key and a secret, so can anyone tell me (or better yet, post a code snippet) the way to format an HTTP call to post an email? The part I seem to be stuck on is generating the access token. Can I generate an access token once to be used at my server to authenticate calls to the CC API? Thank you.
