How to install my API key into an existing template

[EdV1]

I bought a Parallax responsive template I have edited and there is already a newsletter signup embedded.

I need to know now that I have signed up for my API key how do I make it work with my site so that the data in the form fields is sent to my constant contact database and I am notified when this happens.

My test site is here:

the form is just below Our Services

Is your website static or are you using a programming language like PHP, Ruby, Java, etc?

If you can let me know what language your site supports I can help you with the integration :)

Thanks,

Mike

The page is an index.html file itself but I think it's using java - here's the code now:

       <!-- Newsletter-->
        <div class="newsletter">
        
            <div class="container clearfix">
            
                <h3 class="white newsletter">Our newsletter:</h3>
            
                <form id="newsletter"  method="post">
                    <input type="text" onfocus="if(this.value == 'E-mail here') { this.value = ''; }" onblur="if(this.value == '') { this.value = 'E-mail here'; }" value="E-mail here" class="newsletter-email">
                    <input type="text" onfocus="if(this.value == 'Your name') { this.value = ''; }" onblur="if(this.value == '') { this.value = 'Your name'; }" value="Your name" class="newsletter-name">
                    <button type="submit" class="newsletter-sent">Submit</button>
                </form>
            
            </div>
        
        </div>
        <!--/Newsletter-->

Any update or further information on how to make the API work? Site launch is Monday and need to try to iron this out. Thanks for your help!
