// See Global Unlock Sample for sample code.

Chilkat.Http http = new Chilkat.Http();
bool success;

// Implements the following CURL command:

// curl -G https://api.clickatell.com/http/sendmsg \
//   -d "api_id=xxxx" \
//   -d "user=yourUsername" \

// Convert a cURL Command to HTTP Source Code

Chilkat.JsonObject queryParams = new Chilkat.JsonObject();
queryParams.UpdateString("api_id","xxxx");
queryParams.UpdateString("user","yourUsername");
queryParams.UpdateString("password","yourPassword");
