Simulate "Convert" option

Simulate "Convert" option

Greetings, zoho experts,

I had automated the "convert to account, contact" option in zoho crm, because i am copying the information in two additional custom modules. The thing is i want to simulate all the actions in the convert button. I am talking about the "convert" button in the Leads module. When you click it it convert it to account and contact but also the lead module is disabled. 
How can i disabled the Lead module after I had copied the information? It's Urgent please help me!

Best Regards, 
Vladimir
