HTTP Status 401 - Application data not found for key: Client

[DaveR50]

https://api.constantcontact.com/ws/customers/client/contacts?email=user@domain.com  give me a 401 error.

I also get prompted for user/password and the user/password for this forum does not work for the api.

What needs to be done to use the api?

Hello,

In order to use our API, you must have an API key.  The username for the api is "APIKEY%username", and then your password is your regular password.

If you have any questions please let me know.
