Populating Zoho CRM Modules using C# SDK

Populating Zoho CRM Modules using C# SDK

All,

      We have a SQL database with data that we need to upload to Zoho. I have been experimenting with the C# SDK but the authentication step is not clear to me in this scenario.

      While I can manually use the Self-Client option to generate a grant token, it is not feasible to do that from a stand-alone app that run as a scheduled task at night. Since the App has no callback URL, it cannot receive grant tokens from Zoho. What are my options?

      Also, is there a way to use the SDK to connect to Zoho and get a new grant token pushed to the callback URL (which would be received and stored in a database for retrieval by the scheduled app)?

      Thanks,

Armando
