API & Token

0 Votes



I am using an older wordpress plugin for a short campaign here and it is asking me for my API keys and Token from Constant Contact.

I purchased Constant Contact for this purpose just a while ago and contacted support and they sent me here.

Please help generate these for me. Thank you.

Hello user3451925,


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.


We have two different versions of our API, so the steps you take to get this information will depend on what version of our API the integration you are looking to connect with uses as they are created through different platforms and are not cross compatible.


If the app you are using is asking you for an API Key and Secret, 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:



If the app you are using is asking you to provide an “Access Token”, please follow the steps at the following link instead:

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