Hello user524453,


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.


It sounds like you are trying to use a 3rd-party app that is asking you for an API Key. 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.


If you are using an integration that is asking for an API Key and Access token, you will need a legacy V2 API key, which is different from the V3 API keys generated via the Developer Portal, and not cross compatible. We have two different versions of our API, so the steps you take to generate an API key will depend on what version of our API the integration you are looking to connect with uses, as they are created through different platforms.


If the app you are using is asking you to also provide an “Access Token” with your API key, then it most likely utilizes our legacy V2 API, and you'd want to follow the steps at the following link instead:

*You will need to create a Mashery login for V2, as it does not use the same UN/PW as your Constant Contact account


However, if the app you are using is asking you for an API Key and Secret, then it most likely utilizes our V3 API (the key that you generated). You can find the steps to create a new application by clicking to expand the section “How do I Get an API Key?” at this link:


Please have a look and let us know if you have any other questions!
