I'm a web develop but am new to api. I just obtained the api key. I just want to bypass the double sign up when somebody signs up fro mthe site. I only want an input box for their name and email and that's it. What's the first step here?
There are two options. First you could use our Contact Contact Signup Form Generate, this is a step based wizard flow that will build you a custom PHP signup form that you can embed directly into your website: http://community.constantcontact.com/t5/Documentation/Constant-Contact-Signup-Form-Generator-CCSFG/b...
If this doesn't fit your needs, you would be able to create your own custom form using our API. You would need to be able to Create a Contact and also would want to make sure that if a Contact already exists that you have an update flow.
