Announcing our brand new Campaign Builder!

Does anybody have an example of setting up Postman to do API calls to Constant Contact?

0 Votes

Hi there, I'm trying to do something simple...set up Postman to do simple API calls so that I can explore the Constant Contact API and prep our actual backend engineers to be able to build a cool integration. I'm personally not an Oauth2 expert, so I need some simple instructions to be able to make this work. I've done a bunch of searching but none of the solutions seem to work for me (or I just don't know enough to do it correctly).

Thanks, Neil

Hello Neil,


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.


Sorry for any difficulty getting started with authorization, I know the process can seem a little daunting when first getting started. While our expertise is with our API itself as opposed to its implementation within any particular programming language or software, we are happy to answer any questions pertaining to Constant Contact’s API endpoints, functionality, and documentation.


I'm going to follow up with you via email with some additional information at the address on file for the account you are posting from. If you do not receive me email, please feel free to reach out to us at and reference case #30547402 and let us know the best email address to reach you at.


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