Hello. I'm working with integration Zoho with our application. Trying to use BULK write API. With accounts i have no problem, but I need to get contact assigned to company. So i can't find ability to assign Account .id by csv file. 

During single export i add {Account_Name: {id: account_id }} to request body aтd get my contact assigned. 

May I implement my requirements by sending only bulk write requests? or i have to send additional requests for each uploaded contact?

Thanks for your attention:-)
