Tracking leads and accounts

Tracking leads and accounts

We have a substantial amount of integration between our site (and our proprietary database) and Zoho CRM.  One problem we run into is that we would like to be able to track both Leads and Accounts.  The problem we run into is the following scenario:

1. A user signs up on our site.  Our application uses the Zoho APIs to create a lead in Zoho CRM and notes down the resulting Lead ID.  

2. A sales person at our company converts the lead to an Account and at the same time realizes that the company name that was input has some errors in it.  They correct these errors.

3. Our application needs to sync some data between Zoho and our own database.  It searches for the lead in Zoho and does not find it - indicating that the lead has been converted (or deleted).  It then searches for the account, but since the account name has been changed it does not find it, leading our application to believe that the lead was deleted or never created (due to a possible failure in the initial API call).  

When using the normal Zoho GUI, if i click on a converted lead, it will tell me which Contact, Account, and Potential that lead was converted to.  Is this information recoverable in any way from the Zoho API?  Essentially, I need a way of using the lead ID to find the new Account ID.

thanks,
