For well-informed help, please read and follow the instructions in the "How to get the best out of the forum" linked at the head of every forum category.
I think you are supposed to pass the TCP/IP Client to the HTTPClient::begin() function, along with the URL. I don't see where you created a GSM Client.
thank for your reply sir ,
this was just a part of my code and I have created GSM client. I would like to share my full code with you. I have just deleted the google script id.

So compare your sketch to the example sketch to see if you are doing anything differently. Or start over with the HttpClient example and build your sketch on that. Make sure you test often so you can detect a failure early.
