Getting the Ownership, Relationship, and Industry

I'm a developer at a company who uses Zoho CRM and we are currently in the process of integrating via the API.

I'm looking to get the values "Ownership", "Relationship", and "Industry". On Modules and Fields, I found Ownership and Industry to be under the Account module. However I can't seem to find the Relationship field. Could you please point me in the direction as to where I could grab this value via the API?

Thanks and I really hope to get a reply soon as I currently have some backlog tasks with the Zoho API.
