Hey Kevin, 401 means the credentials you are passing are not correct. You can read more about that here: 401 The file you are including is part of a larger project that auto generates a form for people to use to have a custom signup form added to their website. If you are not using this and are only using the file to create your own signup form, you may want to use another wrapper which is better suited for that type of usage. You can find this wrapper here: wrapper Because that file you are using is part of a bigger project, it also requires another file called config.php. Since you got a 401 error and not another error code, it appears this config.php file does exisit on your server but perhaps the credentials stored in that file are not correct and thus why you are getting a 401. Please double check that file. If all checks out, please either DM me that information so I may test using your credentials or you can email webservices AT constantcontact DOT com The above code has been tested and works with the mentioned files. I'm sure we can figure out a solution for you. Thanks,
