I would like to add an API Key to my client's website so that new e-mail subscribers are being automatically added to the constant contact account.
Could someone please walk me through this?
You have several options. You can use our Formstack integration to make a new signup form for the website without requiring any real coding on your end. You could also use the Constant Contact Signup Form Generator, which involves installing files on your server to generate a working signup form.
Lastly, you could use our API to write your own code to have new contacts added to your account. We have code samples available here, and you can generate an API Key here.
