Kinjal,

You are recommended to use data driven request system, not direct by upload

insert request to data & run loop

C#

httpWebRequest2.MaximumResponseHeadersLength = 100000;
                    httpWebRequest2.ReadWriteTimeout = 200000;

you get set your own value

plz refer below given bulksms's api sample

Good Luck

C#

* If you see of the error "'HttpUtility' is not declared", you are probably
