title: Constant Contact V3 API add new contact
body: <p>I'm attempting to use the new Constant Contact V3 API to add a new email contact. I've been reading the docs: <a href="https://v3.developer.constantcontact.com/api_guide/client_flow.html" rel="nofollow noreferrer">https://v3.developer.constantcontact.com/api_guide/client_flow.html</a>, and trying it out and it seems like the only way to do this now is to make an authentication request, approve the request and then retrieve and access token that is valid for only 2 hours.</p>
  <p>I need to have access from my server only and just send an add contact request to Constant Contact. I don't understand why I require to have a redirect uri now and an access token to use the V3 api instead of just using the api key.</p>
  <p>With the V2 api I was able to make these types of requests directly from the server without hassle and that's exactly what I need now. The V2 documentation seems to be taken down so I can no longer do that so I'm stuck.</p>
  <p>Any help is appreciated.</p>
