Client Alerts API not working

Question
When trying to make calls to Client Alerts API's, you will often get "Invalid" data error, or you will get a successful response with no data in the response.

The reason you may be getting the "Invalid" data error, is you MUST URL-encode the ClientAlertsAuthToken for the Login call and both the SessionData and SessionID when making a GetUserAlerts call (when making the call via URL).

For more details on the steps to take in order to make a GetUserAlerts call, refer to article https://ebaydts.com/eBayKBDetails?KBid=1973
