My question is specific for iContact API. I have register an application and get API id. But I am not able to find accountId and clientFolderId.
Please see this below link :
http://developer.icontact.com/documentation/request-your-accountid-and-clientfolderid/ At above page "Perform a GET on the Accounts resource" How I can perform this to get account id and clientfolderid.
The only way to work with the iContact API, is to send correct headers to the server, then you will be able to make any of the requests and actions that appear in the documentation.
The best way that I found to do this is by setting up a PHP script with cUrl
Here you get your accountId and the rest is just calling the right url with this script!
Hope it gives you a hint.
"Keep up the good coding."
