Hello Rinkul,
Thank you for reaching out to the API Support team here at Constant Contact.
I was not able to locate an email from your address within our email queue at all. I did find a couple of calls to our main support team. It looks like you are in need of an API Key to connect a 3rd party plugin to your Constant Contact account.
Since this process was designed for developers, it can be confusing for non-developers to find this information. To help de-mystify the process for everyone, we have a blog post which walks through step-by-step instructions on how to get that information.
How to generate an API Key and Access Token:

Please have a look and let me know if you have any other questions!
Sincerely,
David B.
