EA Protection & Licenses

Hi guys,

I need a code to carry out a web request to verify account number and password to secure my ea template. So when the ea is started a webrequest is done to check if account number and passwords is authorized to use the EA. API part is all set up

the list is in the following format 

so the steps are

1. login to api

2.check if account number and password are there.

3. if account number and password are there, run the EA. IF not shut down EA.

number of account number          password

12345....                                      example...........

I have attached some code if it helps.
