Here's the basic idea of what I need to do. I'm going to create different email lists in my Constant Contact account that represent groups of experts in different categories of small business. When a visitor comes to my site, they can use the form I will devolop to select a category and ask a question. When they click "Submit" the question will be sent, via Constant Contact, to the emails in the chosen list.
Keep in mind, I am a complete newbie to API. Building the form is no problem. Connecting it to Constant Contact and allowing the user to choose which list it is send to is what I need help with.
Constant Contact is unfortunately unable to directly assist with coding and setting up API Integrations. What we can offer is sample code that you can use to start with and modify to meet your goals. You can find these samples, which are complete with instructions and documentation, here. These samples are available in C# ASP.NET and PHP.
