HTTP Status 401 - Application data not found for key

[MichaelN243]

I am trying to write a script that will call the CTCT API to see if an email already exists in our contacts. For some reason, my username and/or my developer key aren't working -- how do I go about fixing this? 

<?php

//HERE'S WHERE THE DECLARATION OF VARIABLES WOULD BE. 

require('cc_api/ConstantContact.php');

$ConstantContact = new ConstantContact('oauth2', $cc_api_key, $cc_username, $cc_api_secret);

//Just trying to grab a list of the contactlists for now to make sure I can authenticate

$Contacts = $ConstantContact->getContacts();

?>

Any help would be appreciated.

Hello Nick,

Based on the code and error message you have posted, it appears that you are working with the V1 API wrapper, but are using a V2 API key. Unfortunately these two systems each have unique keys that cannot be used interchangeably.

If you generate a new V1 API key, you should be able to use your code immediately. You can create an API key for use with V1 API here : http://community.constantcontact.com/t5/Documentation/API-Keys/ba-p/25015

If you do experience any further difficulties, please reply to this post and I will be happy to assist you!

Sincerely,
