General #

The default URI is localhost:9450/api for all GET and POST requests.
You must pass an Authorization header supplying the password if it’s enabled in the SAMMI Settings.
For GET requests supply parameters in the URL query, for POST requests supply parameters in the request body.

Using C#? System.Net.ServicePointManager.Expect100Continue must be set to false to stop the header “Expect: 100-Continue” from being sent with the request as SAMMI will not handle it properly.
