Hi Nandini,
> This got integrated.
No, it is not.
What you got is you provided valid authorization info to the server and got the content of the index.php page. Note, that you got it as a plain html source that, most probably, requires additional processing before it can be displayed in a browser. Also note, that your code just executed basic web request and obtained response. This means that neither web browser will be opened nor obtained page html source will be rendered somewhere.
Follow https://community.smartbear.com/t5/TestComplete-General-Discussions/Integration-TestRail-and-TestComplete/td-p/120998 thread and the one referenced in it to get a better understanding of what and how can be done to get/set data in TestRail using its API.
