I have a username and password that I use to login to Addthis. The username is my email address. When I try to access the API for analytics, I provided my email and password, however the API request does not authenticate.
Below is an example:
http://api.addthis.com/analytics/1.0/pub/shares.json?userid=me@domain.com&password=mypass
Where can I find the credentials I need to use to access analytics?
