Hello..

We are trying to integrate Quickbooks APIs in our POS application. 

We have some doubts regarding below queries. Please go through these and let us know the solution.

1. Can we have 2 different line items for Discounts? when synching the pos data for integration with quickbooks,
is it possible to send multiple line item for sales (eg default income, sales services, sales retail, etc) and
also for discounts (eg default discount, discount 1, discount 2, etc) to same account or different? what APIs do we follow for this?
2. while synching the reconciliation to quickbooks we realised that products were created with the same name eg variance, default income etc. why is that and how is that happening

3. Can we store Quickbooks token for longer time?
In development mode tokens are expiring every half an hour. Is there any way that the token can have longer expiry?
4. What is the procedure to move from development mode to Production mode and if we move whether any of the API key name will change upon migrating to production mode? Previously when we integrated Quickbooks API, APIs key name was name and id. Now it is changed to nameField and idField.
