Thank you for reaching out to Constant Contact API Developer Support. My team is here to assist outside software developers with questions about building into Constant Contact’s API.
Usually an application developer will generate their own API Key that lets their app integrate with Constant Contact, however some developers require you to provide them with an API Key. Since this process was designed to be done by the app developers themselves, it can be confusing for end users to find or generate this information.
According to the Magic Touch Software integration page for Constant Contact, they ask that you contact their Customer Support team for assistance in requesting an Access Token for your account.

Here’s the Magic Touch Software contact page if you need further assistance with the integration.
